DESCRIBE THE ISSUE IN DETAIL:

We're seeing some issues where developers are not able to build the project after moving classes around. Although there are multiple cases where this seems to happen the easiest repro we found was starting off with a project that defines two library projects with the same packageName, then building, then changing the package name and then trying to build again. In this case the BuildConfig class of the original package name as well as the new package exist in the final apk located in app/build/intermediates/apk/debug/app-debug.apk

Software/Hardware

Android Studio Bumblebee 2021.1.1 Android Gradle Plugin 7.1.1 Gradle 7.4 OS: Mac OS 10.15.7

STEPS TO REPRODUCE:

Import the attached project in Android Studio
Connect an Android device of API 29
Click the run button
Check the APK in app/build/intermediates/apk/debug/app-debug.apk to see that it contains just 4 classes com.example.app.BuildConfig, com.example.app.R, com.example.lib.BuildConfig and com.example.lib.R
Change the packageName value in lib/src/main/AndroidManifest.xml to com.example.lib.a.
Click run button again.
Check app/build/intermediates/apk/debug/app-debug.apk again it now contain 6 class files, a BuildConfig in each of the packages com.example.app, com.example.lib and com.example.lib.a

You'll also see that a dex file exists for both BuildConfig classes in lib/build/.transforms as in the attached screenshot
