Finding package imports with javac

[alt-romes]

Hello everyone, I've been struggling with this for a while so I decided to finally post it here.

I'm trying to lint a java file with javac, but it get's stuck in import errors. I've troubleshooted a bit so I'll say all I think could help fix it.

Project structure (some folders omitted for clarity)

The problem would seem to be that javac is running from /Users/romes/fct/dn-rm-collab/SD/sd2021-tp1/src/tp1/server instead of /Users/romes/fct/dn-rm-collab/SD/sd2021-tp1/src/tp1/, but then again, the mvn project is located in /Users/romes/fct/dn-rm-collab/SD/sd2021-tp1/, so again I don't know.

I've tried changing the source path to both directories, the class path to the class dir created by maven, but all without success.

Everything else needed by maven works, just my own package and imports aren't.

Thank you for your help

I was able to fix this by editing let l:src_dir = ale#path#FindNearestDirectory(a:buffer, 'src/main/java') to let l:src_dir = ale#path#FindNearestDirectory(a:buffer, 'src') in ale_linters/java/javac.vim.
It would be better to be able to specify the source directories to find.
I could try doing this but I don't know vim script at all, and this shouldn't be too hard for anyone else who knows this - to add an config option that changes the source path(s) to find.
