Picking a specific build type in a dependency

Question

Suppose I have an Android app with three build types:

buildTypes {
    release {
        ....
    }
    optRelease {
        ....
    }
    debug {
        ....
         


        

Answer 1

If you want to add a dependency for a variant that combines a product flavor and a build type, then you must initialize the configuration name in the configurations block.（如果想为自定义的buildTypes来添加dependencies，需要配置configurations {}）

android {
    buildTypes {
        release {
            ....
        }
        optRelease {
            ....
        }
        debug {
            ....
        }
    }
}

configurations {
    // Initializes a placeholder for the optReleaseImplementation dependency configuration
    optReleaseImplementation {}
}

dependencies {
        debugImplementation xxx
        // Then it can work
        optReleaseImplementation xxx
        releaseImplementation xxx
    }
