Gui pom fails to launch in some projects

[laim2003]

Actual behavior

This is a weird bug, but it seems like the gui in some project fails to launch due to the parent tag in the pom.xml file. In my case however, this only seems to fail in certain situations:

No CVEs found for version 3.9.15 of tool mvn.
No CVEs found for version 8u412b08 of tool java.
Version 8u412b08 of tool java is already installed

Please use (git-)bash (integrated in Windows Terminal) for full IDEasy support:

Weirdly, when running in a different project, it suddenly works (example here, the ideasy development project):

It seems to be failing in newly set up projects.

[laim2003]

even after removing the parent tag, it still fails to resolve the dependencies in certain projects. However, when replacing the version in the gui pom with a stable release, it suddenly works.
