How to remove mockable-android-23.jar automatically?

Question

I just upgraded to Android Studio 2.0. I usually back up my project weekly and do a clean project before backup, after the backup I noticed that my backup is growing by about 12 MB.

I drew a large size, it comes from the "generated" folder in the "build" folder. My previous backup to Android Studio 2.0 does not have this folder.

Inside the folder there is a file called mockable-android-23.jar about 22 MB in size.

Is this generated automatically? How to automatically delete it when cleaning up a project?

Answer 1

I have the same problem after upgrading to Android Studio 2.x. You have no such problem in 1.5.x (Build -> Clean project) done automatically for me.
