I got the same error message as @anonymous_user_f00cc662 except I also had this message:
Distributing 47 actions to XGE (TaskId:15)
Maximum number of concurrent builds reached. (TaskId:15)
This might look like a red herring (it did to me at first), but if you get this error, open up Task Manager and check if there are any orphaned ShaderCompileWorker threads. I had 2 of them. After ending those tasks my project starting building again 
P.S. The quote after -Quiet is supposed to be there. In Visual Studio’s error message it just looks wrong
