I got a lastest Release version : Version: 2022-12 (4.26.0) Build id: 20221201-1913 ，My Web project is kind of gradle builder , When debug in web runtime ,sources of web module work well but api module can't lookup the source ,and appears "edit source lookup " view , however adding source directories or project type ,still unfound it , Never met before version，that can work it well on the main application or junit s test debug environment ，other I tried it in the Version: 2022-09 (4.25.0) Build id: 20220908-1902 still same as before . 。

Anything in the error log that looks relevant? Just to confirm I got it correctly, you are only seeing this in 4.26 and not in 4.25?

Thanks! Looks this warrants a bug. At this point, I am not sure whether this belongs in JDT or M2E, but since the exception has root in M2E, we can start with a bug there:
