Maven2 Dashboard Plugin
The Maven 1.x dashboard is such a tool. The Maven site is integrated into our continuous integration process, and the dashboard that is generated provides a birds-eye view of a lot of our quality metrics. This is especially useful when dealing with multi-module projects. For the Maven2 build system a similar plugin is currently available on Codehaus. However this plugin is not final yet and in the past we had some trouble to get it to work. Therefore we decided to try and build our own plugin.
