Android gradle：在产品口味之间共享依赖项 [英] Android gradle: Sharing dependencies between product flavors

问题描述

我的应用程序中有3种产品口味（flavor1，flavor2，flavor3）。 flavour1和flavour2共享一些与广告相关的依赖项。

I have 3 product flavors (flavor1, flavor2, flavor3) in my app. flavor1 and flavor2 share some of the dependencies related to ads.

是否可以将与广告相关的依赖项捆绑到gradle维度或配置中，并将其添加到flavor1和flavor2中，而无需在build.gradle中复制compileFlavor1和compileFlavor2行？

Is there a way to bundle the ad related dependencies to a gradle dimension or configuration and add that to flavor1 and flavor2 without duplicating the compileFlavor1 and compileFlavor2 lines in my build.gradle?

这是我目前的主要目标。这可行。但是，我想知道是否有更好的方法可以做到这一点？因此，我不必为每种口味重复广告依赖性。

This is part of my current gradle. This works. But, I'm wondering if there is a better way to do this? So, I don't have to repeat the ad dependencies for each flavor.

android {
    productFlavors {
        flavor1 {}
        flavor2 {}
        flavor3 {}
    }

    sourceSets {
       main {}
       flavor1.java.srcDir 'common/ads/java'     <--- shared sourceSet
       flavor2.java.srcDir 'common/ads/java'
       flavor3.java.srcDir 'common/no_ads/java'
    }
}

dependencies {
    compile 'dependency1'
    compile 'dependency2'

    compileFlavor1 'dependency3'   <----- Same list
    compileFlavor1 'dependency4'
    compileFlavor1 'dependency5'

    compileFlavor2 'dependency3'   <------ Same list
    compileFlavor2 'dependency4'
    compileFlavor2 'dependency5
}

推荐答案

共享风味之间的依赖关系的解决方案（已针对实现更新，没有w替换了 compile ）：

Solution for sharing dependencies between flavors (updated for implementation which has now replaced compile):

由于实现， flavor1Implementation ， flavor2Implementation 等实际上都是配置，您实际上可以在构建过程中的这些步骤之间应用继承关系。

Since implementation, flavor1Implementation, flavor2Implementation, etc. are all in fact themselves Configurations you can actually apply an inheritance relationship between these steps in the build process.

因此，在这种情况下，您可以指定共享的依存关系，以及仅对 flavor1 的依存关系：

Therefore in this case you can specify your shared dependencies, and dependencies for flavor1 only:

dependencies {
    implementation 'dependency1'
    implementation 'dependency2'

    flavor1Implementation 'dependency3'
    flavor1Implementation 'dependency4'
    flavor1Implementation 'dependency5'
}

...然后简单地允许 flavor2Implementation 从 flavor1Implementation 继承：

...And then simply allow flavor2Implementation to inherit from flavor1Implementation:

configurations.flavor2Implementation.extendsFrom(flavor1Implementation)

这也可以用来定义口味之间更复杂的关系，并且支持多重继承，例如：

This can also be used to define more complex relationships between flavors, and multiple inheritance is supported, e.g:

configurations {
    flavor3Implementation.extendsFrom(
            flavor1Implementation,
            flavor2Implementation
    )
}

（最后，请注意，共享按照原始问题，应继续使用 sourceSets 处理风味之间的 code 。）

(Finally, just a note that sharing code between flavors should be continued to be handled with sourceSets as per the original question.)
