Who publishes this
Something concrete is wrong: the id claims a namespace this repository does not own, or the build does things a build should not. Flatsonar warns twice.
- org.gnome.gDiagram claims the org.gnome namespace but is hosted by github.com/packerlschupfer and does not build the owner's code
