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);
}
}
