What do you mean by 'not present in the source code'? Annotation processors generate code before the whole codebase is compiled, any tool can analyse the generated lombok source code, the same as with any other code-generating annotation processor.
You do have a point, but if a tool is able to parse Java them I believe it is trivial to extend it to support Lombok, which by now is a quasi standard and fundamental component of a lot of java projects.
Edit: why anyone in their right mind would downvote this comment?
Probably because there is enough people that also value being able to always trace the code written by less experienced team members?
Hint: it is in bad manner to discuss voting on HN. Voting is a popularity contest. If you want your comments to be popular try to be pleasing to everybody and if you don't, don't get upset by downvotes.
