DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of the present application.
[0022] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second" are usually a category, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents a "or" relationship between the front and rear associated objects.
[0023] The application packaging method provided by the embodiments of the present application will be described in detail below in combination with the drawings and specific embodiments and their application scenarios.
[0024] Referring to Figure 1 An implementation flowchart of an application packaging method provided by an embodiment of the present application is shown, and the method can include the following steps: S110: determining a target resource set suitable for a target channel according to the identification of the target channel and the resource declaration file of the application development framework project.
[0025] The resource declaration file includes path declaration of each resource in the resource directory stored in a modularized manner according to channels, each path declaration is associated with one or more applicable channel identifiers, and the resource directory includes a main channel resource directory for storing common resources and other channel resource directories for respectively storing differentiated resources of each other channel.
[0026] In the embodiment of the application, the official release channel of the developer is regarded as the main channel, and other channels such as application markets are regarded as other channels. The target channel can be the main channel or any one of the other channels. In the case of application packaging demand for the target channel, the technical solution provided in the embodiment of the application can be executed to generate an application package for the target channel.
[0027] The embodiment of the application differentiates and standardizes the management of resources to ensure that only the resources used by a channel are packaged into an application program for the channel, so that the uncontrollable risk caused by manual copying of resources can be avoided. The resources can include at least one of a picture file, an audio file, a video file, a font file or a text file.
[0028] The resources can be stored in a modularized manner according to channels in advance. For example, the resources are not directly stored in the main project, but are stored in a separate module project, such as a module named component_asset. In the module, a structured resource directory is established: a main channel resource directory (such as assets) for storing common resources, and a plurality of other channel resource directories (such as assets_channel1 and assets_channel2) for respectively storing differentiated resources of each other channel (such as channel1 and channel2). It can be understood that the resources are divided into two categories: one is common resources, i.e. resources used by the main channel, and other channels can also use the resources of this category, which are stored in the main channel resource directory, such as component_asset / assets; the other is differentiated resources used in some other channels, which are stored in other channel resource directories with the identifiers of the other channels as suffixes, such as component_asset / assets_channel1 for the differentiated resources of the other channel channel1 and component_asset / assets_channel2 for the differentiated resources of the other channel channel2.
[0029] It should be noted that in the embodiment of the application, the resources used by a channel can be understood as the resources used by the application program of the channel.
[0030] In the embodiments of the present application, the application development framework can be Flutter (an open source cross-platform application development framework). In Flutter, referencing resources requires writing the paths of these resources into a resource declaration file (such as pubspec.yaml), and only in this way will these resources be packaged at build time. It can be understood that the resource declaration file is used to manage resources that need to be packaged. Alternatively, a script can be used to automatically read resources, add path declarations of each resource in the resource declaration file, and associate one or more applicable channel identifiers, such as flavor identifiers, with each path declaration. This can improve efficiency and accuracy compared to manual addition.
[0031] Each resource in the main channel resource directory has at least one channel identifier. For example, all resources under component_asset / assets have at least one default-flavor identifier, indicating that the resources in the main channel resource directory will be used by the main channel, and may also be used by other channels. The default-flavor identifier can be understood as the flavor identifier of the main channel, which can be agreed as main.
[0032] For example, the path declaration of a resource is associated with [main, channel2], indicating that the resource is referenced when building the application of the main channel main and other channels channel2; and the path declaration of a resource is associated with [channel1], indicating that the resource is referenced when building the application of other channels channel1.
[0033] The resource declaration file can explicitly show the ownership relationship between resources and channels.
[0034] When there is a need to package an application for a target channel, the identifier of the target channel can be determined first. For example, when building the application of the target channel, a flavor parameter can be passed in to determine the identifier of the target channel. Then, according to the identifier of the target channel and the resource declaration file, a target resource set applicable to the target channel is determined, and the resources in the target resource set are the resources that need to be actually packaged, achieving on-demand introduction.
[0035] S120: According to the identifier of the target channel and the resource access constant file, determine the access path of each resource in the target resource set.
[0036] The resource access constant file includes static constants for accessing resources.
[0037] In Flutter, the access path of a resource can be automatically read by a script, and the resource access constant file is automatically written as a static constant for external use. Compared with manually passing in the access path of the resource, this method can improve efficiency and accuracy. The resource access constant file can be a dart file.
[0038] The resource access constant file includes a series of static constants for accessing resources, and each static constant corresponds to a resource.
[0039] After determining the target resource set suitable for the target channel, the access path of each resource in the target resource set can be determined according to the identifier of the target channel and the resource access constant file.
[0040] S130: Obtain the configuration parameter name corresponding to the target channel based on the preset parameter configuration file.
[0041] The configuration parameters of the same function in the parameter configuration files corresponding to different channels use the same name. Optionally, the parameter configuration files corresponding to each channel are stored in a subdirectory named by the channel identifier under the project root directory.
[0042] It can be understood that the application programs of different channels usually need different configuration parameters, such as server addresses, keys required by third-party software development kits (Software Development Kit, SDK), etc. The embodiments of the present application standardize the management of these configuration parameters. An independent parameter configuration file is created for each channel, and is stored in a standardized path in the project. For example, some configuration parameters required by the application programs of different channels are written in JavaScript (a programming language) object notation (JavaScript Object Notation, json) format into different parameter configuration files, which are stored under the channel folder in the project root directory, such as channel / config_channel1, channel / config_channel2, etc.
[0043] When there is a need to package the application for the target channel, the configuration parameter name corresponding to the target channel can be passed in based on the preset parameter configuration file, such as by --dart-define-from-file. It is necessary to ensure that the configuration parameters of the same function use the same name, and when reading these configuration parameters, the corresponding configuration parameter name is passed in by String.fromEnvironment. In this way, when constructing the application programs of different channels, the required configuration parameters can be read. The configuration parameters and the channels are decoupled and managed centrally.
[0044] S140: Based on the access path of each resource in the target resource set and the configuration parameter name corresponding to the target channel, execute the build command of the application development framework to generate an application package for the target channel.
[0045] After determining the access path of each resource in the target resource set suitable for the target channel and obtaining the configuration parameter name corresponding to the target channel, the build command of the application development framework can be executed to generate an application package for the target channel. The application package is adapted to the target channel, the resource configuration is accurate, and the configuration parameter is correct.
[0046] Take the flutter as an example to illustrate the construction process.
[0047] Developing a Flutter application can use Android Studio (an Android integrated development tool) or VSCode (a software developer tool). When the run button is clicked directly, it cannot be distinguished which channel application is currently being built, so the running parameters need to be configured for the developer to choose which application needs to be debugged and run: If Android Studio is used, a channel package configuration file is added under the.run folder in the project root directory, and the identification and configuration parameters of the corresponding channel are added to the parameter list, such as --flavor=channel1 and --dart-define-from-file=channel / config_channel1. If VSCode is used, some channel package configuration files are added under the configurations field in the.vscode / launch.json in the project root directory, and the identification and configuration parameters of the corresponding channel are added to the parameter list, such as --flavor=channel1 and --dart-define-from-file=channel / config_channel1.
[0048] According to the method provided in the embodiments of the present application, resources are modularly stored according to channels, and a resource declaration file and a resource access constant file of an application development framework project are generated. According to the identifier of a target channel, the access path of each resource in a target resource set applicable to the target channel can be obtained by using the resource declaration file and the resource access constant file. Based on the access path of each resource in the target resource set and the parameter configuration file corresponding to the target channel, a build command of the application development framework is executed to generate an application package for the target channel. The target channel is any one channel, and the scheme can be applied to each channel for application packaging. The scheme can realize standardized and efficient multi-channel packaging, and is helpful to improve the application development efficiency.
[0049] In some embodiments of the present application, the file name of the resource in the main channel resource directory is consistent with the file name of the corresponding differentiated resource in the other channel resource directory. The resource declaration file is generated by the following steps: scanning all resources in the main channel resource directory; for each resource scanned, determining whether there is a resource with the same file name as the current resource in the other channel resource directory; if there is a resource with the same file name as the current resource in the first other channel resource directory in the other channel resource directory, creating a first path declaration for the current resource, the first path declaration pointing to the path of the current resource in the main channel resource directory, and associating the identifier of the main channel and the identifiers of the other channels except the first other channel; if there is no resource with the same file name as the current resource in any other channel resource directory, creating a second path declaration for the current resource, the second path declaration pointing to the path of the current resource in the main channel resource directory; scanning all resources in each other channel resource directory respectively; for each resource scanned, creating a third path declaration for the current resource, the third path declaration pointing to the path of the current resource in the other channel resource directory, and associating the identifier of the corresponding other channel.
[0050] For convenience of description, the above steps are combined for description.
[0051] In the embodiment of the present application, the file name of the resource in the main channel resource directory is consistent with the file name of the corresponding differentiated resource in the other channel resource directory. For example, the first resource is stored in the main channel resource directory, and the first resource will be replaced by the first target resource in the application program of a certain other channel. The first target resource is stored in the other channel resource directory corresponding to the other channel, and the first target resource is a differentiated resource. The file name of the first resource stored in the main channel resource directory is consistent with the file name of the first target resource stored in the other channel resource directory.
[0052] In the process of generating the resource declaration file, all resources in the main channel resource directory can be scanned first. For each scanned resource, it is determined whether there is a resource with the same file name as the current resource in the other channel resource directory. The current resource refers to the resource to which the current operation is directed.
[0053] For example, all resources in component_asset / assets are scanned to determine whether the file name of each resource exists in each other channel resource directory.
[0054] If there is a resource with the same file name as the current resource in the first other channel resource directory in the other channel resource directory, the current resource is considered to be a differentiated resource of the first other channel corresponding to the first other channel resource directory. In this case, a first path declaration is created for the current resource, the first path declaration points to the path of the current resource in the main channel resource directory, and is associated with the identifier of the main channel and the identifiers of the other channels except the first other channel. That is, the channel identifier associated with the current resource excludes the first other channel to ensure that the main channel resource directory of the differentiated resource is not mistakenly packaged when building the application program of the first other channel.
[0055] For example, the resource with the same file name as the resource center_bg.webp in the main channel resource directory component_asset / assets exists in the other channel resource directory component_asset / assets_channel2. The path of center_bg.webp in the main channel resource directory can be added under the flutter:assets: node of pubspec.yaml, and is associated with the identifiers (flavor) of all other channels except channel2, such as main and channel1, and the format is as follows: / / pubspec.yaml flutter: assets: - path: assets / images / center_bg.webp / / This is a differentiated resource, which will be packaged into the application only when the application corresponding to the main channel main and the application of other channels channel1 are built; flavors: - main - channel1 If any other channel resource directory does not have a resource with the same file name as the current resource, the current resource can be considered a general resource, which can be used by all channels. In this case, a second path declaration can be created for the current resource, which points to the path of the current resource in the main channel resource directory. The identifier of all channels can be associated, or no channel identifier can be associated.
[0056] For example, if there is no resource in any other channel resource directory with the same file name as the resource ic_home.webp in the main channel resource directory component_asset / assets, the path of ic_home.webp in the main channel resource directory can be directly added to the flutter:assets: node of pubspec.yaml, as follows: / / pubspec.yaml flutter: assets: - assets / images / ic_home.webp / / This is a general resource, which is used in the application of the main channel and the application of other channels.
[0057] After all the resources in the main channel resource directory are scanned, all the resources in each other channel resource directory can be further scanned. For each resource scanned, a third path declaration is created for the current resource, which points to the path of the current resource in the other channel resource directory corresponding to the other channel resource directory where the current resource is located. The identifier of the other channel corresponding to the other channel resource directory where the current resource is located is associated. The path declaration corresponding to each resource scanned in the other channel resource directory only associates a single channel to which it belongs.
[0058] For example, all resources in component_asset / assets_channel1 and component_asset / assets_channel2 are scanned, and the paths of these resources are added to the flutter:assets: node of pubspec.yaml with the corresponding channel flavor, as follows: / / pubspec.yaml flutter: assets: - path: assets_channel2 / images / center_bg.webp / / This is a differentiated resource, which will be packaged into the application only when building the application of other channel channel2; flavors: - channel2 The application embodiment can automatically and accurately pre-generate or update the resource declaration file through scanning and comparison, can reduce resource coverage errors, omissions or redundant packaging problems caused by manual maintenance, and ensure the accuracy of resource distribution.
[0059] In some embodiments of the application, the resource access constant file can be generated by the following steps: scan all resources in the resource directory; According to the file name of the scanned resource, generate a static constant corresponding to each resource according to the preset naming rule; Based on the storage distribution of each resource in the resource directory, assign a value to the static constant corresponding to each resource; Based on the static constant and its value corresponding to each resource, generate a resource access constant file according to the syntax rules of the target programming language.
[0060] For convenience of description, the above steps are combined for description.
[0061] In the embodiments of the application, all resources in the main channel resource directory and each other channel resource directory can be automatically scanned by a script, and according to the file name of the scanned resource, a static constant corresponding to each resource can be generated according to the preset naming rule. Alternatively, the static constant can be named using the camel case naming method.
[0062] Based on the storage distribution of each resource in the resource directory, the value of the static constant corresponding to each resource can be determined.
[0063] Optionally, for each resource in the resource directory, if the file name of the current resource only exists in the main channel resource directory, the value of the static constant corresponding to the current resource is determined as the path of the main channel resource directory; If the file name of the current resource exists in the main channel resource directory and at least one other channel resource directory, the value of the static constant corresponding to the current resource is determined as a conditional expression, and the conditional expression is used to dynamically analyze the path according to the channel identifier; If the file name of the current resource only exists in the second other channel resource directory, it can be considered that the current resource is only in the second other channel resource directory, and is a differentiated resource. The value of the static constant corresponding to the current resource can be determined as the path of the second other channel resource directory.
[0064] For each resource in the resource directory, there are three storage distribution situations of the current resource in the resource directory. One is that the file name of the current resource only exists in the main channel resource directory. Another is that the file name of the current resource exists in the main channel resource directory and in one or more other channel resource directories. The third is that the file name of the current resource only exists in one other channel resource directory.
[0065] If the file name of the current resource only exists in the main channel resource directory, it can be considered that the current resource is only in the main channel resource directory, and is a general resource. The value of the static constant corresponding to the current resource can be determined as the path of the main channel resource directory.
[0066] If the file name of the current resource exists in the main channel resource directory and at least one other channel resource directory, it can be considered that the current resource is a differentiated resource. The path corresponding to the main channel resource directory and the path corresponding to the other channel resource directory can be determined as a conditional expression for dynamically resolving the path according to the channel identifier. For example, for a same-name picture resource existing in the main channel resource directory and the other channel resource directory channel1, the value of the static constant corresponding to the resource is a conditional expression for determining whether to use the path under assets or assets_channel1 according to the channel identifier (such as the value of appFlavor) at the time of compilation.
[0067] If the file name of the current resource only exists in the second other channel resource directory, it can be considered that the current resource is only in the second other channel resource directory, and is a differentiated resource. The value of the static constant corresponding to the current resource can be determined as the path of the second other channel resource directory.
[0068] For example, all resources under the main channel resource directory component_asset / assets are scanned first. For each resource, it is determined whether a resource with the same file name as the resource exists in other channel resource directories (such as component_asset / assets_channel1 and component_asset / assets_channel2).
[0069] If none exists, the resource is a general resource. The static constant corresponding to the resource is named in small camel case according to the file name of the resource. The static constant and its value format are as follows: static const String icHomeWebp = 'packages / component_asset / assets / images / ic_home.webp'.
[0070] If exists, such as center_bg.webp exists in component_asset / assets_channel1, but does not exist in component_asset / assets_channel2, the static constant corresponding to the resource and its value format reference as follows: static const String centerBgWebp = 'packages / component_asset / ${(appFlavor == channel1)? 'assets_$appFlavor' : 'assets'} / images / center_bg.webp'.
[0071] If center_bg.webp exists in component_asset / assets_channel1 and component_asset / assets_channel2, the static constant corresponding to the resource and its value format reference as follows: static const String centerBgWebp = 'packages / component_asset / ${(appFlavor == channel1 || appFlavor == channel2)? 'assets_$appFlavor' : 'assets'} / images / center_bg.webp'.
[0072] For the case that the file name of the resource exists in the main channel resource directory and at least one other channel resource directory, it is necessary to determine whether to take the path of the resource under the main channel resource directory or the path under the other channel resource directory according to the channel identification parameter (such as --flavor parameter) passed in during construction and the resource directory where the resource is located.
[0073] Then scan the resources under each other channel resource directory, such as component_asset / assets_channel1 and component_asset / assets_channel2, and write the resources that do not exist in the main channel resource directory (i.e., the resources under component_asset / assets) into the resource access constant file in the form of a small camel case named static constant, and the format of the static constant and its value is as follows: static const String centerBgWebp = 'packages / component_asset / assets_$appFlavor / images / center_bg.webp'.
[0074] The resource access constant file can accurately obtain the access path of each resource in the target resource set applicable to the target channel. The resource access constant file is automatically generated or updated by a script in advance, and the developer does not need to manually write and maintain a large number of resource path strings, which can effectively solve the problems caused by spelling errors and update delays, improve the development efficiency, and improve the maintainability of the code.
[0075] In some embodiments of the present application, the method can further include the following steps: In the case where the resource directory is changed and / or the resources in the resource directory are changed, the resource declaration file and the resource access constant file are regenerated.
[0076] In the embodiments of the present application, the resource declaration file and the resource access constant file can be generated based on the resources in the resource directory. After the resource declaration file and the resource access constant file are generated, the resource directory can be changed, and / or the resources in the resource directory can be changed, such as adding a certain other channel resource directory, deleting a certain other channel resource directory, adding a certain resource, or deleting a certain resource. In this case, the resource declaration file and the resource access constant file need to be regenerated so that when there is a packaging requirement for an application facing a target channel, the accurate resource access path can be obtained based on the updated resource declaration file and the resource access constant file.
[0077] In some embodiments of the present application, the method can further include the following steps: Based on the configuration parameter name corresponding to the target channel, the configuration parameter corresponding to the target channel is obtained; The configuration parameter corresponding to the target channel is encoded to generate an encoded configuration string; The encoding configuration string is transmitted to the native platform through a build command of the application development framework, so that the native platform decodes the encoding configuration string to obtain an original configuration parameter string, and then splits the original configuration parameter string into key-value pairs for use by the native code.
[0078] For convenience of description, the above steps are combined for description.
[0079] In cross-platform development, configuration parameters on the side of an application development framework (such as flutter) need to be synchronized to the side of a native platform (such as Android or iOS). During building, the configuration parameters corresponding to a target channel can be obtained based on the configuration parameter name corresponding to the target channel, the configuration parameters corresponding to the target channel are encoded (such as base64 encoding), and an encoding configuration string is generated. The encoding configuration string is transmitted to the native platform through a build command of the application development framework, such as --dart-define-from-file of flutter. During the building stage of the native platform, the encoding configuration string can be read by a building tool of the native platform, and then the encoding configuration string is decoded to obtain an original configuration parameter string. The original configuration parameter string is split into key-value pairs, so that the native code can use the same configuration parameters as the application development framework by accessing the key-value pairs.
[0080] In this way, the parameter barrier between the application development framework (such as flutter) and the native platform is broken down, so that the native code can use the same set of configuration parameters as the application development framework, ensuring the unity and correctness of the entire application configuration.
[0081] In some embodiments of the present application, the method can further include the following steps: According to the identification of the target channel, the business logic code corresponding to the target channel is obtained; The build command of the application development framework is executed based on the access path of each resource in the target resource set and the parameter configuration file corresponding to the target channel, and an application package facing the target channel is generated, which can include the following steps: The build command of the application development framework is executed based on the access path of each resource in the target resource set, the parameter configuration file corresponding to the target channel, and the business logic code corresponding to the target channel, and an application package facing the target channel is generated.
[0082] It can be understood that in addition to resources and configuration parameters, certain channels can require specific business logic. In the embodiments of the present application, business logic code can be written separately for each channel, and the business logic code corresponding to different channels is distinguished by channel identification (such as through the appFlavor constant).
[0083] When there is an application packaging requirement for a target channel, the business logic code preset for the target channel can be obtained according to the identifier of the target channel. During construction, the business logic code corresponding to the target channel and the main project code are compiled together.
[0084] In this way, the clarity of the core business logic is ensured, the channel customization logic is easy to manage and remove, and the maintainability and readability of the code are improved.
[0085] The above detailed description of the technical solutions provided by the embodiments of the present application shows that the embodiments of the present application abandon the various inconveniences and potential risks that may be caused by manual writing of resource indexes, realize automatic construction of resource indexes through standardized management of resources and script processing, and realize the ability that related resources are packaged into an application only when needed by a channel package to be constructed, thereby effectively avoiding the problem of expansion of the package size caused by support for multi-channel packaging. In addition, by configuring each difference parameter in a file and standardizing the naming of the parameters, a set of parameter reading code can be used on the Flutter side and the native side to adapt different channel packages. Furthermore, in combination with the ability of multi-variant packaging of a native platform (such as Android, iOS, and HarmonyOS), a set of projects can be used to construct multi-channel applications.
[0086] The embodiments of the present application have at least the following advantages: Easy to maintain: the main channel application and other channel applications completely share a set of projects, and different channel applications can be constructed directly using the construction command of the application development framework, without interfering with each other when constructing multi-channel applications, thereby reducing the difficulty of maintenance; Cross-platform: supporting construction of channel packages for multiple system platforms such as Android, iOS, and HarmonyOS based on an application development framework (such as Flutter); High efficiency: resource management is completely handled by scripts, avoiding repetitive manual work and improving development efficiency; Extensible: for subsequent possible addition of channels, only simple configuration is required to support, and good extensibility is achieved.
[0087] It should be noted that in the embodiments of the present application, in resource differentiation management, the resources are not limited to separate local modular management, but can also be stored in the main project or as an independent module and then published online to realize remote dependency; the specific script implementation is not limited to Dart implementation, but also includes other arbitrary script implementations such as python and shell; In parameter and code differentiation management, it is not limited to using --dart-define-from-file to pass parameters. --dart-define can also be used. These parameters can be read in the code through String.fromEnvironment, or int.fromEnvironment or bool.fromEnvironment can be used depending on the actual type of the parameter.
[0088] It should be noted that the application packaging method provided in this application embodiment can be executed by an application packaging device, or by a control module within the application packaging device for executing the application packaging method. This application embodiment uses the execution of the application packaging method by an application packaging device as an example to illustrate the application packaging method provided in this application embodiment.
[0089] See Figure 2 The diagram shown is a structural schematic of an application packaging device provided in an embodiment of this application, comprising the following modules: The resource determination module 210 is used to determine the set of target resources applicable to the target channel based on the identifier of the target channel and the resource declaration file of the application development framework project. The resource declaration file includes the path declaration of each resource in the resource catalog that is modularly stored by channel, and each path declaration is associated with one or more applicable channel identifiers. The access path determination module 220 is used to determine the access path of each resource in the target resource set based on the identifier of the target channel and the resource access constant file. The resource access constant file includes static constants used to access resources. The parameter name acquisition module 230 is used to obtain the configuration parameter name corresponding to the target channel based on the preset parameter configuration file. Parameters with the same function in the parameter configuration files corresponding to different channels use the same name. The application package generation module 240 is used to execute the application development framework's build command to generate an application package for the target channel based on the access path of each resource in the target resource set and the configuration parameter name corresponding to the target channel.
[0090] The apparatus provided in this application provides modular storage of resources by channel and generates resource declaration files and resource access constant files for the application development framework project.

The first path declaration points to the path of the current resource in the main channel resource directory and is associated with the identifier of the main channel and the identifiers of other channels other than the first other channel. If no resource with the same filename as the current resource does not exist in any other channel resource directory, a second path declaration is created for the current resource, which points to the path of the current resource in the main channel resource directory; Scan all resources in each of the other channel's resource catalogs; For each scanned resource, a third path declaration is created for the current resource. The third path declaration points to the path in the resource directory of another channel where the current resource is located, and is associated with the corresponding identifier of the other channel.

[0094] In some embodiments of the present application, the application packaging device 200 further includes a file updating module, configured to: In the case that the resource directory is changed and / or the resource in the resource directory is changed, the resource declaration file and the resource access constant file are regenerated.
