For me, switchting to a different project groups fixes this error (at least 
most of the time)

Yes, usually that helps for me too, but here neither Clean&Build, restarting 
the IDE or just reloading the projects helped.

After playing around a bit more, I had some findings:

a) cleaning the cache in user dir brings some improvements
So to say, almost all imports are resolved now (and due to that most of the 
other stuff works), except those from the other project in the container. And 
this issue disappears after another clean build (maybe or not).
But of course, this is not a valid option for less experienced users.

b) the issue seems to appear only, if I load the project for the very first 
time, so the gradle supports detects problems, which are to be resolved by a 
primer build

c) as soon as any issue appears with the build files, the import statement 
issues are back
Only restarting the IDE helps.

d) between various restarts of the IDE the issues mentioned in the first mail 
might appear or not

Hmm, very mysterious that.

Anyway, it's hard to provide reliable steps to reproduce, as with another 
project container it didn't happen at all :(

Thanks

    This usually goes away for me if I reload the project after building to 
ensure the classes being imported have been compiled.  It would certainly be 
better if that wasn’t required.

    Hi,

    I have a gradle container project consisting of two sub projects.
    Clean, Build, Run, Debug, etc.works properly as it should from NetBeans.

    But... every single import statement is marked as "package does not exist". 
This applies to

      * imports from external libraries
      * imports from the other project
      * imports from the same project, but a different package


    This causes a lot of follow-up problems (e.g. not working code completion, 
tons of markers in the side bar about issues), which are quite inconvenient to 
work with. It feels like working with a simple text editor, that has a bit of 
code coloring and formatting capabilities.
    There is also another nasty side effect: When creating a new class in a 
project, the file is created, but misses the package declaration. (But even 
after adding it manually, the class is still unknown to other classes)


    So, my question is:
    Might it be, that a gradle project in NB, that is depending on other gradle 
projects is not able to use the classpaths given in the project settings (which 
are all shown)? Or is it just ignoring those?

    Further information:
    Windows 10, Gradle 7, OpenJdk 16

    --- Thanks in advance
    C.
