<h1 id="feedback">Feedback and Troubleshooting</h1>
<p>If things do not work, especially simple things like <code>ant -version</code>,
  then something is wrong with your configuration. Before filing bug reports and
  emailing all the Apache Ant mailing lists</p>
<ol>
  <li>Check your environment variables. Are <code>ANT_HOME</code> and <code>JAVA_HOME</code> correct? If
    they have quotes or trailing slashes, remove them.</li>
  <li>Unset <code>CLASSPATH</code>; if that is wrong things go horribly wrong. Ant does not
    need the <code>CLASSPATH</code> variable defined to anything to work.</li>
  <li>Make sure there are no versions of <samp>crimson.jar</samp> or other XML parsers in <samp>JAVA_HOME/jre/lib/ext</samp></li>
  <li>Is your path correct? is Ant on it? What about <samp>JAVA_HOME/bin</samp>? have you tested
    this? If you are using Jikes, is it on the path? A CreateProcess error (especially
    with <code>error=2</code>) on Windows usually means executable not found on the path.</li>
  <li>Which version of ant are you running? Other applications distribute a copy
    -it may be being picked up by accident.</li>
  <li>If a task failing to run is from <samp>optional.jar</samp> in <samp>ANT_HOME/lib</samp>? Are there any
    libraries which it depends on missing?</li>
  <li>If a task doesn't do what you expect, run <code>ant -verbose</code> or <code>ant
    -debug</code> to see what is happening</li>
</ol>
<p>If you can't fix your problem, start with the <a href="https://ant.apache.org/mail.html" target="_top">Ant
  User Mailing List</a>. These are other ant users who will help you learn to
  use ant. If they cannot fix it then someone may suggest filing a bug report,
  which will escalate the issue. Remember of course, that support, like all open
  source development tasks, is voluntary. If you haven't invested time in helping
  yourself by following the steps above, it is unlikely that anyone will invest
  the time in helping you.</p>
<p>Also, if you don't understand something, the <a href="https://ant.apache.org/mail.html" target="_top">Ant
  User Mailing List</a> is the place to ask questions. Not the developer list,
  nor the individuals whose names appears in the source and documentation. If
  they answered all such emails, nobody would have any time to improve Ant.</p>
