Gradle 中基于多风味库的单风味模块

我正在研究多种口味app。 （下面的gradle文件）

它使用一个名为的库tracker遵循相同的口味internal and external

现在对于棘手的部分来说，有一个名为的新模块feature，这个没有味道，但需要tracker作为依赖

应用程序.gradle：

android {

    buildTypes {
        debug {
        }
        release {
        }
    }

    flavorDimensions "target"

    productFlavors {
        internal {
            dimension "target"
        }

        external {
            dimension "target"
        }
    }
}

跟踪器.gradle：

android {

    publishNonDefault true

    buildTypes {
        release {
        }
        debug {
        }
    }

    flavorDimensions 'target'

     productFlavors {
        internal {
            dimension "target"
        }

        external {
            dimension "target"
        }
    }
}

功能.gradle：

android {
    compileSdkVersion rootProject.ext.compileSdkVersion

    defaultConfig {
        compileSdkVersion rootProject.ext.compileSdkVersion
        buildToolsVersion rootProject.ext.buildToolsVersion

        defaultConfig {
            minSdkVersion rootProject.ext.minSdkVersion
            targetSdkVersion rootProject.ext.targetSdkVersion
            versionCode 1
            versionName "1.0"
            javaCompileOptions {
                annotationProcessorOptions {
                    includeCompileClasspath false
                }
            }
        }
    }

}

dependencies {
    implementation(
            [...]
            project(':tracker')
    )
}

这里有errors当我尝试梯度同步:

Unable to resolve dependency for ':feature@debug/compileClasspath': Could not resolve project :tracker.

Could not resolve project :tracker.
Required by:
    project :feature
 > Project :feature declares a dependency from configuration 'implementation' to configuration 'externalRelease' which is not declared in the descriptor for project :tracker.

Unable to resolve dependency for ':feature@debugAndroidTest/compileClasspath': Could not resolve project :tracker.

Could not resolve project :tracker.
[...]

我的gradle版本是4.4。

在文档中，安卓开发者 and Android 插件 DSL 参考表明，应该添加以下代码。

missingDimensionStrategy 'external'
missingDimensionStrategy 'target'

但这对我不起作用。最后我在feature.gradle中添加以下代码。

flavorDimensions 'target'

 productFlavors {
    internal {
        dimension "target"
    }
}
