Maven Repository Server Plugin
This plugin exposes Hudson builds as Maven repositories. Unlike the Jenkins variant my plugin supports the new Maven 3 Integration in Hudson 2.1
Display Name Plugin
This plugin adds a display name property to Hudson jobs, and provides a column to display it. The use case is that the normal name property needs to be unique and valid for a file system.
Dependency Viewer Plugin
This plugin is a fork of the original dependency graph view plugin. I have forked the plugin since its pom only states Jenkins compatibility, and because I wanted to add some features to show how individual builds was connected instead of just job level.
