Maddening error when trying to add Google Leaderboards

So my project was working just fine until I added the Google Play Services so I could use the leaderboards. Now, I can't build my project with the error "Failed to repackage sources, see console for details". Here are the details:

 Error building Player: CommandInvokationFailure: Failed to re-package resources. See the Console for details.

If someone could PLEASE help I'd be so grateful as Google provides no support and this is something I really need in my game. THANK YOU!
