title: Example '.hgignore' file for a Vaadin 8 project under Mercurial using IntelliJ
body: <p>I am seeking guidance as to what files and folders I might consider ignoring when placing a <a href="https://vaadin.com/framework" rel="nofollow noreferrer"><em>Vaadin Framework</em></a> 8 project into version control using <a href="https://en.wikipedia.org/wiki/Mercurial" rel="nofollow noreferrer"><em>Mercurial</em></a> with IntelliJ 2017 IDE. I am looking for examples of <a href="https://www.mercurial-scm.org/wiki/.hgignore" rel="nofollow noreferrer"><code>.hgignore</code></a> files to use.</p>
  
  <p>I want to avoid the unpleasantness of later wrestling with the version control system to get it to forget files which never should have been included in the repository. </p>
  
  <p>I create my Vaadin projects via the <a href="https://vaadin.com/docs/framework/v8/getting-started/getting-started-archetypes.html" rel="nofollow noreferrer">Maven archetypes provided</a> by the Vaadin.com team.</p>
