When I see some one complaining code generation being design smell I gag a little at this hackneyed Fowler expression. I'm curios what do you think lambok does?
It does code generation. What id does not is _source_ code generation. That is, you never see the code Lombok generates, never have to maintain it, and never have a chance to break it by editing. You can see it as a macro substitution.
OTOH IDE-generated code is "normal" source code, adding boilerplate to your "real" code, not tracking changes in it automatically, and perfectly breakable.
