The plugin-report:report Goal

To generate the documentation of your plugin, execute the following on the command line:

mvn plugin-report:report

The xdoc files, one per goal, are generated by default in ${project.build.directory}/generated-site/xdoc, and an overview is generated in the site output.

If you add the plugin to the reporting section of your pom, you'll get the full report as html with mvn site.
