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

Question

I just upgraded to Android Studio 2.0. I usually backup my project weekly and do clean project before backing up, after backup I noticed that my backup go up around 12mb in size.

I traced the big size, it comes from 'generated' folder in 'build' folder. My previous backup before Android Studio 2.0 does not have that folder.

Inside the folder, there's a file called mockable-android-23.jar with around 22mb size.

Is this auto generated now? How to auto delete it when cleaning up project?

Answer 1

i have the same issue after upgraded to Android Studio 2.x. Don't have such issue under 1.5.x (Build -> Clean project) done automatically nicely for me.
