NullPointerException in compiler, Java files with red error badges can't be run

Open bernard01 opened this issue 3 years ago • 0 comments

Apache NetBeans version

Apache NetBeans 15

What happened

At NetBeans startup with a project group containing a single project, after the cache was deleted. The problem occurred before. That is why I deleted the cache.

The project where the exception occurs worked before for a long time just a few weeks ago. Now it is broken and I cannot work with it.

The project compiles without errors when compiled from the Projects window context menu.

The "broken" java files are in the unit test hierarchy of a Maven project.

I cannot navigate to the "broken" java files highlighted in red. But when I copy the name of such a file and use "Go to Type" to navigate to it then that works, and the file it navigates to is good.

I may be able to provide more info, but this will require some work. So I wait and see whether something obvious can be discovered from the log.

How to reproduce

I may be able to provide a reproducible test case. But perhaps I may not be able to because from experience, after simplifying projects to a test case, the problem often disappears. messages.log
