App won't execute on new Android Studio 2.2 with gradle 2.14.1 with Instant Run enabled

Question

I just installed the newer Android Studio 2.2 and I'm in trouble while building my project:

Error:Execution failed for task ':app:processDebugAndroidTestResources'.
  java.io.FileNotFoundException: [path_to_project]/app/build/intermediates/symbols/androidTest/debug/R.txt (No such file or directory)

I'm using gradle version 2.14.1 (because this version of the IDE force me to use it).

If I disable instant run everything works ok, but it is a shame to lose all of a sudden this feature.

Any help?

EDIT:

I tried the following but the error still happen:

• Clean the project.
• Re-imported the project as an external source into Android Studio.

Answer 1

Finally I found the problem, I had one dependency added two times (one in the normal build plus the same in the test environment). I managed this and instant run worked again.
