> Annotation processors must be explicitly declared now.  The following dependencies on          


        

Answer 1

You should explicitly add annotation processors in gradle. Putting the following in your gradle dependencies should fix it:

annotationProcessor 'com.google.auto.value:auto-value:1.1'

However, as others have already mentioned, you should probably figure out which of your existing dependencies was using auto-value to assert whether or not you really need it. Annotation processors ultimately slow down your build time so don't include it if it's unnecessary.
