Manifest Merge Problem

Hello, I faced the problem with manifest merging. I use custom manifest. And i got error when i am adding permission.C2D_MESSAGE permissions. Without it there no errors. How to understand the problem? I checked libraries and there no thoose permissions. I'm using Unity 5.6.1f1 Uncaught translation error: java.lang.IllegalArgumentException: already added: Lcom.mylib.test/Manifest; Uncaught translation error: java.lang.IllegalArgumentException: already added: Lcom.mylib.test/Manifest$permission; Manifest Code: Update: I just tried build via gradle and there no errors, seems internal builder is bugy
