Gamepad errors

I'm trying to add controller compatibility to my project but everything downloadable fromthe greenfoot gamepads section seems to be outdated. I'm prompted to update the code and either way I get a ton of errors all similar to this. Is there a more up to date version out there or is there another way to add controllers to Greenfoot? I've been considering doing something with getKey() but I'd rather not if there's a better way to do things.
