  <p>Here is how i generate the files for one folder:</p>
  
  <pre><code>&lt;plugin&gt;
              &lt;groupId&gt;org.jvnet.jaxb2.maven2&lt;/groupId&gt;
              &lt;artifactId&gt;maven-jaxb2-plugin&lt;/artifactId&gt;
              &lt;executions&gt;
                  &lt;execution&gt;
                      &lt;goals&gt;
                          &lt;goal&gt;generate&lt;/goal&gt;
                      &lt;/goals&gt;
                  &lt;/execution&gt;
              &lt;/executions&gt;
              &lt;configuration&gt;
                  &lt;schemaDirectory&gt;src/main/resources/xsd&lt;/schemaDirectory&gt;
              &lt;/configuration&gt;
          &lt;/plugin&gt;
  </code></pre>
