Hello. I'm experimenting with modularizing an existing plugin (japicmp [0]) and am running into hundreds of errors of the form:

org.apache.maven.artifact.factory from both maven.artifact and maven.core This looks to be a case of split packages amongst all of the various Maven artifacts. I'm adding dependency exclusions to try to work around the issues, but I'm not confident that'll actually work. Are there efforts underway to clean this stuff up? The reason I'm modularizing the plugin is due to this: "To build and run japicmp under Java 1.9, you must add the following module: java.xml.bind. This can be done for the maven plugin for example by: export MAVEN_OPTS="--add-modules java.xml.bind" I'd rather not have to do this as I'm committed to having all of my project builds run without needing extra Maven flags: "mvn clean install" *must* just work on every system, no exceptions. Am I undertaking a fool's errand trying to get this stuff to work cleanly? If not, is there any documentation on modularizing existing plugins?
