I think the decision to not export plexus-utils was taken some time ago. Unfortunately, the xml bits still have to be provided by the maven core class loader. I think in this case, Maven 3.9.x should also expose the builder class
<exportedPackage>org.codehaus.plexus.util.xml.Xpp3DomBuilder</exportedPackage> I think this should work, but this would only solve the problem for the latest 3.9.x maven, not older versions.
