Regarding IDE support - I was once on a project using Lombok where some developers used Eclipse and others used IntelliJ. The Eclipse devs wanted to use this new @Builder annotation, which didn't work on IntelliJ but worked fine on Eclipse - for interesting reasons.
I attempted to patch the IntelliJ Lombok plugin to support @Builder - but gave up on it for reasons of time, priority and the fact that I wasn't certain it would work as Lombok continued to change. Also this was an experimental feature at the time that wasn't even certain to become mainline. I learnt a bit in the process.
Lombok works by passing certain switches as arguments to javac, which alters the class files that it writes out based on the annotations. It "confused the hell out of IntelliJ", because IntelliJ's intellisense/auto-complete plugin ecosystem works as so: IntelliJ exposes AST _from source_ to plugins, like the Lombok plugin, which hook in and let IntelliJ know, for instance, there's another method here due to this annotation. So it's constant effort to ensure the plugin's injections line up with what the compiler is actually spitting out.
Eclipse on the other hand is always aligned. I can only infer that it generates its autocompletion etc from the _compiler's output_. So whatever version of Lombok you're using, the autocompletion features will always be aligned.
