title: Relative paths in Ant Property are not working
body: <p>I'm trying to store a relative path to a file in my ant build.xml like this:</p>
  
  <pre><code>&lt;property name="foo" location="somedir/myfile" relative="true"/&gt;
  </code></pre>
  
  <p>According to the Ant <a href="http://ant.apache.org/manual/Tasks/property.html" rel="nofollow noreferrer">manual for Property</a> this is ok syntax, but when running it Ant says: </p>
  
  <blockquote>
    <p>property doesn't support the
    "relative" attribute</p>
  </blockquote>
  
  <p>I'm using Apache Ant version 1.7.1 compiled on August 13 2009</p>
