title: How in Ant output values of properties?
body: <p>In Ant exits task Echo:</p>
  
  <pre><code>&lt;echo message="Hello, world"/&gt;
  </code></pre>
  
  <p>But it seems useless. I need to check values in ant file.
  E.g. </p>
  
  <pre><code> &lt;property file="${user.home}/build.properties"/&gt;
   &lt;echo message="${file}" /&gt;
  </code></pre>
  
  <p>but I receive only:</p>
  
  <pre><code> [echo] ${file}
  </code></pre>
  
  <p>How I can have Ant display value of file?</p>
