Hi! When setting the whole project SDK to Java 21, the core/non-nms module (first module it attempts) fails with this Maven error: "Class com.sun.tools.javac.tree.JCTree$JCImport does not have member field 'com.sun.tools.javac.tree.JCTree qualid'"

Okay I fixed that by upgrading Lombok to 1.18.30. Now I get "Unsupported class file major version 65", even though the whole project is set to SDK 21

are you using lombok?

If so, upgrade lombok to 1.18.32

oh nvm you already did that haha

Fixed it!

Turns out I was using an ancient version of SpecialSource as well, which obviously couldn't read Java 21

Thanks so much for helping! Will credit you in the Spigot post I made about this:)

ah yeah, you'll need version 2.something for java 21

also on macOS btw haha. outdated lombok, outdated java-compiler-plugin, and outdated specialsource plugin lmao
