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

What I did is :

Created product flavors:

    android {
        flavorDimensions 'tier'
        compileSdkVersion 27
        defaultConfig {
            applicationId "com.example.sample"
            minSdkVersion 15
            targetSdkVersion 27
        }

        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
                --------------
            }
            debug {
                debuggable true
            }
        }
        productFlavors {
            qc {
                applicationIdSuffix ".qc"
                dimension "tier"

            }
            production {
                applicationIdSuffix ".production"
                dimension "tier"
            }
        }
    }

Allow dependencies to choose the build types like below

dependencies { 
    qcDebugCompile project(path: ':libName', configuration: "debug") 
    qcReleaseCompile project(path: ':libName', configuration: "release") 
    productionDebugCompile project(path: ':libName', configuration: "debug") 
    productionReleaseCompile project(path: ':libName', configuration: "release") 
... 
}
