title: How to pass Maven settings via environment vars
body: <p>In our setting.xml file we have the following:</p>
  
  <pre><code>&lt;servers&gt;
      &lt;server&gt;
        &lt;id&gt;deploymentRepo&lt;/id&gt;
        &lt;username&gt;repouser&lt;/username&gt;
        &lt;password&gt;repopwd&lt;/password&gt;
      &lt;/server&gt;
  &lt;/servers&gt;
  </code></pre>
  
  <p>Would it be possible to pass those settings (or their equivalent) via environmental variables instead of the settings.xml?</p>
