Android studio 2.0 gradle transformClassesWithDexForDebug fails when using button “run”

Question

I have a problem after migration from android studio 1.5 to 2.0

In one of my project (only one) i can\'t use android studio run button,

because then, build

Answer 1

I have the same problem, on linux. For some reason, some files and dirs inside /build can not be deleted, not even with 'sudo -rf', and this is the origin of the problem for me. I built the project in a MacBookPro and no problem.
