Android Studio - Building library aar file doesn't append flavor or buildType to output

Question

I am running assemble for my library module , I see from logs that it should generate two files myLib-release.aar and myLib-debug.aar inside the myLib/build/outputs/ folder.

However, I always only find one lib there that is myLib.aar, it doesn't matter if I run assemble for both, assembleDbug or assembleRelease.

Why is this happening?

According to this discussion it is an error (or planned feature) in gradle, up to date it is still the same.

https://github.com/gradle/gradle/issues/8328

Workaround can be to implement this:

// in library/library.gradle
afterEvaluate {
    def debugFile = file("$buildDir/outputs/aar/library.aar")
    tasks.named("assembleDebug").configure {
        doLast {
            debugFile.renameTo("$buildDir/outputs/aar/library-debug.aar")
        }
    }
    tasks.named("assembleRelease").configure {
        doLast {
            debugFile.renameTo("$buildDir/outputs/aar/library-release.aar")
        }
    }
}

You may then implement copy tasks as desired.
