<faq id="emacs-mode">
<question>Why doesn't (X)Emacs parse the error messages generated
by Ant correctly?</question>
<answer>

<p>Ant adds a &quot;banner&quot; with the name of the current
task in front of all messages - and there are no built-in
regular expressions in Emacs that would account for this.</p>

<p>You can disable this banner by invoking Ant with the
<code>-emacs</code> switch. Alternatively you can add the
following snippet to your <code>.emacs</code> to make Emacs
understand Ant&apos;s output.</p>

<question>How do I send an email with the result of my build

<answer>

<p>You can use a custom BuildListener, that sends out an email
in the buildFinished() method. Will Glozer
&lt;will.glozer@jda.com&gt; has written such a listener based
on JavaMail, the source is</p>

invoke Ant like</p>

<p>The <code>antRun</code> script in <code>ANT_HOME/bin</code>
has DOS instead of Unix line endings, you must remove the
carriage return characters from this file. This can be done by
using Ant&apos;s &lt;fixcrlf&gt; task or something like:</p>
