body: <p>Every time I try to launch a target in my <code>build.xml</code>, I receive an error. This is the relevant part of my <code>build.xml</code>.</p>

  <p>This is the error in the Eclipse console:</p>
  
  <pre class="lang-none prettyprint-override"><code>BUILD FAILED

  </code></pre>
  
  <p>I use java JDK 131.06. How do I fix my <code>build.xml</code>?</p>
