title: Tag a Repo from a Jenkins Workflow Script
body: <p>I'm currently trying to tag a repo from a Jenkins Workflow script. I've tried using a <code>sh</code> step but this runs into problems because of credentials not being set.</p>
  
  <pre><code>fatal: could not read Username for 'https://&lt;repo&gt;': Device not configured
  </code></pre>
  
  <p>Is there an existing step that can be used either to tag a repo or to get round the credentials problem? </p>
