This is a feature request. I'm a maintainer at detekt. On our gradle plugin we want that if our users execute check we just check the "default variant". We want to mimic the behavior of lint:

If your project includes build variants, lint checks only the default variant. If you want to run lint on a different variant, you must capitalize the variant name and prefix it with lint.

Our problem is that there is not way from gradle-api to get the "default variant". The point where we read the active variants is:

androidComponents.onVariants { variant ->
}

I would expect that variant should have a default property so we can identify which is the "default variant" but nothing like that exists.

Android Studio also uses this concept of "default variant" on the "Build Variant" panel. AS displays all the possible variants of each module adding "(default)" to the default one.

So what we would like is an API at the com.android.tools.build:gradle-api level to know which is the default variant so we can create better integrations with the AGP.

There are some workarounds for this but it forces you to depend on com.android.tools.build:gradle instead of com.android.tools.build:gradle-api I have it implemented on other project. It works but probably it's not bullet proof. At detekt we don't want to depend on com.android.tools.build:gradle. We want just to depend on com.android.tools.build:gradle-api.
