See http://maven.apache.org/guides/mini/guide-ibiblio-upload.html

I modified the root build.xml to also generate the bundle in the correct format.

To facilitate the maven process, the bundle needs to be hosted on a public URL (new process), therefore if you could post it up together with the other artifacts, that would be great. After this, the only thing left to do is to go on http://jira.codehaus.org/browse/MAVENUPLOAD and request the upload.
