title: Setting up a TeamCity VCS Root to pull using a Mercurial tag
body: <p>I am trying to setup a TeamCity build configuration to pull from a Mercurial repository using a Mercurial tag. I have the "Default branch" field of the VCS root set to 'tag name'. Initially I had the "Default branch" field of the VCS root set to 'default' which worked fine but pulls only the tip revision. Here is the TeamCity error that I get:</p>
  
  <pre><code>Failed for the root 'mercurial: http://MyRepository/' #46: Cannot find revision 
  of the default branch 'tag name' of vcs root mercurial: http://MyRepository 
  </code></pre>
  
  <p>What am I doing wrong?</p>
  
  <p>Thanks in advance for any replies!</p>
