HelpMojo seems to be something to do with Maven Plugin Plugin. It 
doesn't seem to be present in nar-maven-plugin 3.3.0 or 3.5.0

$ java --module-path nar-maven-plugin-3.5.0.jar --list-modules 
nar.maven.plugin at 3.5.0 (file:///d/nar-maven-plugin-3.5.0.jar)
   requires mandated java.base
   exports com.github.maven_nar
   exports com.github.maven_nar.cpptasks
   exports com.github.maven_nar.cpptasks.arm

We have tried out hundreds of libraries as automatic modules (to test 
the derivation comes up with sensible module names etc.) and haven't 
seen too many issues. I did come across javacc, not the others you mention.

The summary is that if you have libraries with types in the unnamed 
package then they will need to remain on the class path. This means that 
nobody will be able to use `requires` to name them as a dependence in 
their module declaration.
