The Maven team is pleased to announce the Dashboard plugin 1.1 release!

http://maven.apache.org/reference/plugins/dashboard

This plugin generates a dashboard HTML report containing information 
gathered from other Maven reports (Checkstyle, Clover, JUnit, Simian, 
etc). The dashboard aggregate this information for all subprojects, 
presenting them in a single tabular format.

Changes over version 1.0:

o Ensure that the Clover plugin will generate the XML report (and only 
  the XML report) when the Dashboard plugin is run. The Clover XML 
  report is required by the Clover aggregators as they extract 
  information from it.
o Do not exclude project.xml in the default  maven.dashboard.excludes
  list as it is already excluded by the default maven.dashboard.includes 
  list.

Note that this plugin has been tested with Maven 1.0 rc2 from CVS HEAD. 
Using it with another version of Maven is at your own risks! :-)

An example of the Dashboard plugin in action is available here:
