For some reasons you may want to ignore your build variants. For example: you have ‘mock’ product flavour and you use it only for debug purposes, such as unit/instrumentation tests.

Let’s ignore mockRelease variant from our project. Open build.gradle file and write:

// Remove mockRelease as it's not needed.
android.variantFilter { variant ->
    if (variant.buildType.name.equals('release') && variant.getFlavors().get(0).name.equals('mock')) {
        variant.setIgnore(true);
    }
}
