Building the plugin from sources: I used and built the sources linked from Geertjan's Blog:

http://hg.netbeans.org/community-ruby

When building the plugin NetBeans (it took a very long time), I got the following error:

Could not load definitions from resource net/sf/antcontrib/antlib.xml. It could not be found

This can be fixed by installing ant-contrib on your system, e.g.:

yum -y install ant-contrib

Find the JAR file (in my case it was located at /usr/share/java/ant/ant-contrib.jar) and add it to Ant's classpath in NetBeans through Tools -> Options -> Java -> Ant -> Add JAR/ZIP.

After that it should build. If you want to use the plugins, right-click the NB Ruby project and click on Package As -> NBMs. This will create an Update Center. You can add this update update center to your NetBeans via Tools -> Plugins -> Settings -> Add where the URL should be:

file:/PathToTheRepository/build/updates/updates.xml

After that you can install the Ruby and Rails plugin.

Happy coding!
