If you are using the Gradle Wrapper (the recommended option in Android Studio), you enable stacktrace by running gradlew compileDebug --stacktrace from the command line in the root folder of your project (where the gradlew file is).
If you are not using the gradle wrapper, you use gradle compileDebug --stacktrace instead (presumably).
You don’t really need to run with --stacktrace though, running gradlew compileDebug by itself, from the command line, should tell you where the error is.
I based this information on this comment:
