org.codehaus.plexus.util.xml.Xpp3DomBuilder$InputLocationBuilder is found in libplexus-utils2-java version 3.2.1, but not in 3.1.1 shipped in stable. I haven't tried the build of CDK locally yet, but I suspect that we're missing a versioned dependency on this library in the maven package. I think your next step (for CDK) is to try installing the newer libplexus-utils2-java [1]. Thank you for taking the time to report this bug. Cheers, tony [1] https://tracker.debian.org/pkg/plexus-utils2
