Different code-server port with gwt-maven-plugin

Hello, for a project we're using the fantastic gwt-maven-plugin, but now we need to migrate a legacy feature of the app to a new version, and we like to run both version of the app (old and new) to compare the results.

We have a difficult, we can't force the code-server to use a port different than the default one (9876) with that maven plugin.

Any idea or hint? Looking the documentation there isn't any option to do that:

Thanks in advance!
