title: FindBugs not showing the bugs found
body: <p>I've used FindBugs before and I didn't have problems, however this time on Eclipse Helios on Ubuntu Natty Narval bugs are found but not shown.</p>
  
  <p>Here's what I tried:</p>
  
  <ul>
  <li>Right Click on the project > Find Bugs > Find Bugs</li>
  <li>Looking at the progress I saw 3 bugs were found</li>
  <li>In the Problems view they are not listed</li>
  </ul>
  
  <p>I tried to go to its own perspective with: Open Perspective > Other > FindBugs but Bug Explorer is empty.</p>
  
  <p>Any ideas to view those bugs? </p>
  
  <p><strong>UPDATE:</strong> In Eclipse error log I see:</p>
  
  <pre><code>!ENTRY edu.umd.cs.findbugs.plugin.eclipse 2 2 2011-06-18 21:13:24.968
  !MESSAGE The following classes needed for FindBugs analysis on project **

  <p><strong>UPDATE 2:</strong> I don't know how to fix Eclipse, but I found a workaround. I added the findbugs report to maven's pom.xml</p>
  
  <pre><code>&lt;reporting&gt;
      &lt;plugins&gt;
          [...]
          &lt;plugin&gt;
              &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt;
              &lt;artifactId&gt;findbugs-maven-plugin&lt;/artifactId&gt;
              &lt;version&gt;2.3.3-SNAPSHOT&lt;/version&gt;
              &lt;configuration&gt;
                  &lt;xmlOutput&gt;true&lt;/xmlOutput&gt;
                  &lt;!-- Optional derectory to put findbugs xdoc xml report --&gt;
                  &lt;xmlOutputDirectory&gt;target/site&lt;/xmlOutputDirectory&gt;
              &lt;/configuration&gt;
          &lt;/plugin&gt;
      &lt;/plugins&gt;
  &lt;/reporting&gt;
  </code></pre>
  
  <p>The following configuration generates an HTML report in target/site/findbugs.html</p>
