title: Maven cobertura plugin - one report for multimodule project
body: <p>I'm using maven cobertura plugin to report code coverage in my multimodule project.</p>
  
  <p>The problem is that I don't know how to generate one report for all modules in project.</p>
  
  <p>So far I have generated separate reports for every module, but it would be nice to have one report for whole project.</p>
  
  <p>My parent pom configuration:</p>
  
  <pre><code>   &lt;plugin&gt;
          &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt;
          &lt;artifactId&gt;cobertura-maven-plugin&lt;/artifactId&gt;
          &lt;version&gt;2.4&lt;/version&gt;
          &lt;inherited&gt;true&lt;/inherited&gt;
          &lt;executions&gt;
              &lt;execution&gt;
                  &lt;phase&gt;test-compile&lt;/phase&gt;
                  &lt;goals&gt;
                      &lt;goal&gt;clean&lt;/goal&gt;
                      &lt;goal&gt;cobertura&lt;/goal&gt;
                  &lt;/goals&gt;
              &lt;/execution&gt;
          &lt;/executions&gt;
      &lt;/plugin&gt;
  </code></pre>
