title: Ant svn revisiondiff
body: <p>Please, help me. I need to find the difference between previous version and the current version in SVN with Ant.</p>
  
  <pre><code>&lt;revisiondiff
      destfile="diff.xml"
      package="ant"
      start="PREV"
      end="HEAD"
  /&gt;
  </code></pre>
  
  <p>But it doesn't work. <code>&lt;svn:revisiondiff&gt;</code> and <code>&lt;svn revisiondiff&gt;</code> do not work too. I added <code>svn</code> in path. Libraries are also connected.</p>
