title: Jenkins how to use AnchorChain plugin to add external URL to Jenkins pipeline
body: <p>I want to link an external URL to Jenkins pipeline. This should be accessible while the build is running. AnchorChain had been suggested in several pages and so trying to use it but the <a href="https://wiki.jenkins.io/display/JENKINS/AnchorChain+plugin" rel="nofollow noreferrer">documentation</a> is less explanatory for a newbie. I installed the AnchorChain Plugin and added the following in the pipeline script.</p>
  
  <pre><code>sh "echo 'File1 http://localhost:8080/api' &gt; anchorChain.tsv"
  </code></pre>
  
  <p>When I start the build, the console output shows </p>
  
  <blockquote>
    <p>+ echo webAppUrlFile  <a href="http://localhost:8181/api" rel="nofollow noreferrer">http://localhost:8181/api</a></p>
  </blockquote>
  
  <p>Now I want to add this link to the sidebar of the build job similar to an HTML Publisher report link. What are the next steps?</p>
