Error Building Apk : com.android.build.api.transform.TransformException: Error while generating the main dex list

Question

After project into two libraries module and one app module Android Studio is unable to build Apk but when I build project into real device into or emulator it work perfectly

this is the full stack error which I've got in Messages Tab

FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.
 com.android.build.api.transform.TransformException: Error while generating the main dex list.

Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Answer 1

I got the error and this was because of having two same classes in two modules. while building Apk all classes should be written to main dex list file and if there is a duplicate class name in it, it fails.

The way I found the duplicate class name was by using --stacktrace in command line options which could be reached by

file > setting > build,execution,deployment > compiler
