Failed to resolve variable '${project.groupId}'

After migrating to androidx, the Android Studio can't resolve dagger-android and dagger-android-support classes, like DaggerAppCompatActivity. Issue link

What I did to solve this is File - Invalidate Caches/Restart.

I have all the time the same Problem, just add something in the Gradle an Sync Again, and the problem was solved, i think is a bug from Android Studio
