maven multi module not working

### Apache NetBeans version

Apache NetBeans 19

### What happened

- when I do change in one module and clean & build project, things not reflected in another module
- javac is working, but not IDE(cannot find symbol, error bulb)

### How to reproduce

1. use maven multi module project
2. do some changes in one module
3. go to second module and change is not reflected

### Did this work correctly in an earlier version?

Apache NetBeans 17

### Operating System

win 11

### JDK

jdk 8-21

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

- every time
- and from second module it jump to javac decompiled code not actual module

### Are you willing to submit a pull request?

Yes

Reproduce the problem with a Maven multi-module project in Apache NetBeans 19 on Windows, changing one module and checking the other module's errors and navigation. Compare the behavior with NetBeans 17 and verify that changes are reflected and navigation reaches the actual module source rather than decompiled javac code.
