Project mention: Unchecked Java: Say Goodbye to Checked Exceptions Forever | news.ycombinator.com | 2023-07-13

This is every Lombok lover's favorite strawman argument I've run into.
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.

Project mention: Flow Updater JSON Creator | dev.to | 2023-12-09
