Maven 'HOT' plugins

Here is the list of my favorite plugins for Maven:

FindBugs: This plugin help find a lot of bug in a Java code.

      <excludeFilterFile>findbugs-excludes.xml</excludeFilterFile>
      <relaxed>false</relaxed>
   </configuration>
 </plugin>
...

Cobertura: This plugin is very useful for checking the code coverage of the unit tests.

     </configuration>
   </plugin>

Source XRef: HTML based, cross-reference version of Java source code.

TagList: Report on various tags found in the code.

Simply do: mvn clean site and look into the target/site directory for the reports generated by these plugins.

In a other blog, I will talk about Hudson integration.
