title: git jenkins and tags all together
body: <p>Is there any way to make jenkins checkout and build a certain tag (<code>parameterized builds</code>?) 
  I'm currently building the development (master branch) and right after tag a version (using <code>maven:release</code>) </p>
  
  <p>some information (as suggested by Vonc)<br>
  Env is win7, latest git, latest jenkins (updated yesterday) .
  I've tried placing the tag name in the <code>Branch Specifier</code> but without luck (either it fails or checking out the <code>master</code> branch). 
  from jenkins log:</p>
  
  <blockquote>
    <p>Fetching changes from 1 remote Git repository Fetching upstream changes from git@github.com:${myorgname}/${myorgname}.git</p>
  </blockquote>
  
  <p>I'm guessing the question is really - where (if any) do I tell jenkins - "hi, don't checkout master branch, just checkout the tag".
  Is there a place I can configure the git command myself? (e.g - <code>git fetch my_tag</code>)</p>
