The crux of the problem is the hudson-war project that depends on bundled plugins - while this is ok when there are releases it can depend on, it doesn't work with snapshots due to the circularity issue. Separating the WAR assembly project out into a different git repository from the core should avoid this. A related issue is the CVS plugin depends on hudson-plugin-parent, which in turn depends on hudson-war, which depends on the CVS plugin... So bundled plugins should either have a different parent to hudson-plugin-parent, or perhaps hudson-plugin-parent should not depend on the WAR file but instead depend on the core?

I don't see any pmd errors locally - what errors do you see?

maven-hpi-plugin.version in core is set to 3.0.0-SNAPSHOT, so afaict it shouldn't be looking for 3.0.1-SNAPSHOT:
