Stuck with Gradle Build Running

Question

While trying to build my Application on Android Studio 2.1 (On Ubuntu 16.04), it gets stuck on the below note:

Executing tasks: [:app:generateDebugSources,          


        

Answer 1

The issue is that the project isn't synced with the gradle files. The resolution I did was go to File > Sync Project with Gradle Files and it was able to sync.
