I somewhat agree with you and reluctant to use Lombok. But it's easy to say "use better language". Kotlin is too different. Java is actually pretty good right now and the only thing I really need is property declaration.

Actually I was thinking about different approach last year, didn't get to implement it. Something like declare abstract class with getX() setX() methods and let library to implement missing methods. Now it's one line per method, no trivial code and able to generate other nice things, e.g. I really want to have fast initializeable properties (like getX throws exceptions until I call setX).
