title: Update Manifest Version From Pom
body: <p>After releasing (and I know Tycho does not support that, but we made it work somehow) I want to change the version of the <em>Manifest.MF</em> automatically from the <em>pom.xml</em> - in the future even in the same build process. </p>
  
  <p>While researching for how to implement a custom Maven plug-in I found the <code>tycho-versions-plugin</code>, which almost seems to do what I want, so I added it to the build:</p>
  
  <pre><code>&lt;plugin&gt;
      &lt;groupId&gt;org.eclipse.tycho&lt;/groupId&gt;
      &lt;artifactId&gt;tycho-versions-plugin&lt;/artifactId&gt;
      &lt;version&gt;${tycho-version}&lt;/version&gt;
      &lt;executions&gt;
          &lt;execution&gt;
              &lt;id&gt;versions&lt;/id&gt;
              &lt;phase&gt;validate&lt;/phase&gt;
              &lt;goals&gt;
                  &lt;goal&gt;set-version&lt;/goal&gt;
              &lt;/goals&gt;
          &lt;/execution&gt;
      &lt;/executions&gt;
      &lt;configuration&gt;
              &lt;newVersion&gt;${project.version}&lt;/newVersion&gt;
      &lt;/configuration&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p>Now this only works if the <em>Manifest.MF</em> and the <em>pom.xml</em> already have the same version, which is useless in my case. Is there some obscure parameter I'm missing or do I really have to develop my own plug-in for the exotic use-case of incrementing the version?</p>
