It’s a very simple plugin, all it does well at this point is create (somewhat) compliant DEB packages from Maven projects that have JAR packaging. If you are interested in creating DEB packages for Java libraries, take a look a “Generating Packages”. I recently paid some attention to the code, and wrote some documentation for this plugin. It was sitting in the Mojo Sandbox for a while, and it didn’t look like it was on any sort of release trajectory.
There’s definitely more work to be done on this plugin, but it is, at the very least, a start. As a part of this effort, I’m also looking into creating a brute-force DEB repository based off of the Maven 2 repository.
