java.lang.IllegalArgumentException: Parameter 'directory' is not a directory in android

Question

I rebuilt my project and got this error. I'm unable to find where it's coming from. The full log is:

I've had the same problem. All I did was:

1. Delete the .gradle directory
2. Invalidate Caches and restart Android Studio.
