title: cxf-codegen-plugin doesn't generate sources
body: <p>I'm trying to get the <em>cxf-codegen-plugin</em> to generate sources from my wsdl file. When calling wsdl2java manual the desired classes are generated but when using <strong>mvn generate-sources</strong> nothing happens and I get the message "No goals needed for project". Calling the plugin directly doesn't helps.</p>
  
  <p>The extract from my poms follows:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;plugin&gt;
      &lt;groupId&gt;org.apache.cxf&lt;/groupId&gt;
      &lt;artifactId&gt;cxf-codegen-plugin&lt;/artifactId&gt;
      &lt;version&gt;2.5.2&lt;/version&gt;
      &lt;executions&gt;
          &lt;execution&gt;
              &lt;id&gt;generate-sources&lt;/id&gt;
              &lt;phase&gt;generate-sources&lt;/phase&gt;
              &lt;configuration&gt;
                  &lt;sourceRoot&gt;${project.build.directory}/generated/cxf&lt;/sourceRoot&gt;
                  &lt;wsdlOptions&gt;
                      &lt;wsdlOption&gt;
                          &lt;wsdl&gt;${basedir}/src/main/MyServiceInterface.wsdl&lt;/wsdl&gt;
                      &lt;/wsdlOption&gt;
                  &lt;/wsdlOptions&gt;
              &lt;/configuration&gt;
              &lt;goals&gt;
                  &lt;goal&gt;wsdl2java&lt;/goal&gt;
              &lt;/goals&gt;
          &lt;/execution&gt;
      &lt;/executions&gt;
  &lt;/plugin&gt;
