Android 构建变体：为除一个变体之外的所有变体声明依赖项

问题描述

我有 5 个构建变体。 4 个不同的构建变体（“内部”）需要一组给定的 gradle 依赖项，而 1 个构建变体（“外部”）则不需要。引用这些依赖项的代码仅位于内部构建变体的 /src 文件夹中。

我能否更简洁地声明“除此变体之外的所有”都需要给定的依赖项列表？

这就是我们现在的应用级 build.gradle 文件的处理方式：

internalDevelopmentImplementation(name:'MyGreatDependency-1.1.0',ext:'jar')
internalDevelopmentImplementation(name:"MyGreatDependency-logger-1.1.0",ext:'aar')
internalDevelopmentImplementation(name:"MyGreatDependency-android-2.0.0",ext:'aar')
internalDevelopmentImplementation(name:"MyGreatDependency-extension-android-1.1",ext:'aar')

internalReleaseImplementation(name:'MyGreatDependency-1.1.0',ext:'jar')
internalReleaseImplementation(name:"MyGreatDependency-logger-1.1.0",ext:'aar')
internalReleaseImplementation(name:"MyGreatDependency-android-2.0.0",ext:'aar')
internalReleaseImplementation(name:"MyGreatDependency-extension-android-1.1",ext:'aar')

internalStageImplementation(name:'MyGreatDependency-1.1.0',ext:'jar')
internalStageImplementation(name:"MyGreatDependency-logger-1.1.0",ext:'aar')
internalStageImplementation(name:"MyGreatDependency-android-2.0.0",ext:'aar')
internalStageImplementation(name:"MyGreatDependency-extension-android-1.1",ext:'aar')

internalProdImplementation(name:'MyGreatDependency-1.1.0',ext:'jar')
internalProdImplementation(name:"MyGreatDependency-logger-1.1.0",ext:'aar')
internalProdImplementation(name:"MyGreatDependency-android-2.0.0",ext:'aar')
internalProdImplementation(name:"MyGreatDependency-extension-android-1.1",ext:'aar')

然后，externalProd 变体根本不声明依赖项。

有什么办法可以改进吗？

解决方法

这里有一个想法：使用配置继承。使用大多数配置共享的依赖项创建配置，在那里设置公共依赖项。让其他人从这个延伸。类似的东西：

configurations {
    // Add the bulk of dependencies to this one:
    commonImplementation {}

internalDevelopmentImplementation.extendsFrom(commonImplementation)
    internalReleaseImplementation.extendsFrom(commonImplementation)
    // And so on
