Neat. Reminds me of lombok in that it really only affects compile-time and makes for cleaner code in a way that many (but not all) developers would want.
There was maybe a time Lombok made sense. It does not anymore. Death to Lombok.
I've been coding in Java professionally for ~20 years. I can count with zero hands the number of times I've been burned by a getter or setter getting changed into something surprising.
If you really need auto-generated getters/setters/builders - Immutables [1] is a library that does it using bog standard annotation processing rules that don't require hacking your build process.
