Hudson can visualize the results of the FindBugs analysis of your class files. When this option is configured and your build runs the maven goal findbugs:findbugs then Hudson provides useful information about analysis results, such as historical result trend, module and package statistics, web UI for viewing analysis reports and warnings, and so on.

You will achieve the best results with the findbugs-maven-plugin version 1.2 or newer. Version 1.1.1 produces an old file format that contains insufficient warning information. So if possible, upgrade to this version. If your pom.xml contains the following configuration then this plug-in will automatically pick up the correct results file:

<plugin>
   <groupId>org.codehaus.mojo</groupId>
   <artifactId>findbugs-maven-plugin</artifactId>
   <version>1.2</version>
   <configuration>
      <findbugsXmlOutput>true</findbugsXmlOutput>
      <findbugsXmlWithMessages>true</findbugsXmlWithMessages>
      <xmlOutput>true</xmlOutput>
      [...]
   </configuration>
</plugin>
