Since the `build-helper-maven-plugin` configuration is identical in both
the gremlin-server/gremlin-console pom.xml files and the "SNAPSHOT detection"
would be generally useful (i think it has value to the GLVs) i think that you
should be able to move that entire configuration to the root pom.xml (where the
`build-helper-maven-plugin` is already being used). I'm pretty sure that doing
that will make that `only.when.is.snapshot.used` to all sub-modules. I think
you can then remove the definition for `build-helper-maven-plugin` from the
`<pluginManagement>` element.
