I don't actually know. Both trees http://developer.onebusaway.org/apidocs/modules/X/version and http://developer.onebusaway.org/modules/X/version/apidocs exist, but it looks like the former has not been updated since early 2011. It looks like <link> elements help resolve @see com.mycompany.plugin.myplugin.MyMojo or {@link com.mycompany.myplugin.MyMojo} links, using the package-list in Javadoc. http://developer.onebusaway.org/modules/onebusaway-gtfs-modules/1.3.2/apidocs/package-list does exist so I suppose it will do the job.
