is there a way to provide a command argument to only a specific annotation processor? not entirely certain if javac distinguishes at all here either...

annotation processors don't declare which options they'll process, and javac doesn't have a mechanism to pass options specifically to one processor (and not the others), it only has

-A

. Gradle doesn't implement any such mechanism either on top of javac. So no you can't target a given option to a specific processor. Options should follow naming rules to avoid name clashes (similarly to system properties)

Yeah... I think the joker on the left and the joker on the right aren't really handling things so wisely. Not a big deal just a warning from one of the jokers.
