title: Ant create filesets, dirsets from (absolute) properties
body: <p>In ant, I have defined some properties that define some paths (<strong>absolute</strong>) needed in my build system.</p>
  
  <p>Most of ant tasks need filesets, so to build a fileset from a property I would have to do:</p>
  
  <pre><code>&lt;fileset dir="" includes="${myprop}"/&gt;
  </code></pre>
  
  <p>The problem is that <code>myprop</code> is absolute and I should omit the dir attribute (<em>which is not possible</em>), so <strong>is there a way to define (absolute) properties and efficiently use them to create filesets, dirsets, etc..</strong> or in ant <strong>is this a bad practice (only relative paths should be used)</strong>?</p>
  
  <p>Thanks.</p>
