<p>The Velocity stylesheets used to process the XML files can
be found in the <code>xdocs/stylesheets</code> subdirectory of
Ant's CVS repository - the build file <code>docs.xml</code> is
used to drive Anakia. This file assumes that you have the
<code>jakarta-site2</code> module checked out from CVS as
well, but if you follow the instruction from Anakia's
homepage, you should get it to work without that. Just make
sure all required jars are in the task's classpath.</p>

<blockquote>
<p>Initially Ant was part of the Tomcat code base when it was
donated to the Apache Software Foundation - it has been
created by James Duncan Davidson, who also is the original
author of Tomcat. Ant was there to build Tomcat, nothing
else.</p>
<p>Soon thereafter several open source Java projects realized
that Ant could solve the problems they had with makefiles.
Starting with the projects hosted at Jakarta and the old Java
Apache project, Ant spread like a virus and now is the build
tool of choice for a lot of projects.</p>
<p>In January 2000 Ant was moved to a separate CVS module and
was promoted to a project of its own, independent of
Tomcat. Ant became Apache Ant.</p>
<p>The first version of Ant that was exposed a lager audience
was the one that shipped with Tomcat's 3.1 release on 19 April
2000. This version has later been referenced to as Ant
0.3.1.</p>
<p>The first official release of Ant as a stand alone product was
Ant 1.1 released on 19 July 2000. The complete release
history:</p>

<blockquote>
<p>Ant's distribution contains file names that are longer
than 100 characters, which is not supported by the standard
tar file format. Several different implementations of tar use
different and incompatible ways to work around this
restriction.</p>
<p>Ant's <tar> task can create tar archives that use
the GNU tar extension, and this has been used when putting
together the distribution. If you are using a different
version of tar (for example, the one shipping with Solaris),
you cannot use it to extract the archive.</p>
<p>The solution is to either install GNU tar, which can be
found <a href="http://www.gnu.org/software/tar/tar.html">here</a>
or use the zip archive instead (you can extract it using
<code>jar xf</code>).</p>

Why does Ant always recompile all my Java files?

<blockquote>
<p>In order to find out which files should be compiled, Ant
compares the timestamps of the source files to those of the
resulting <code>.class</code> files. Opening all source files
to find out which package they belong to would be very
inefficient - instead of this, Ant expects you to place your
source files in a directory hierarchy that mirrors your
package hierarchy and to point Ant to the root of this
directory tree with the <code>srcdir</code> attribute.</p>
<p>Say you have <code><javac srcdir="src"
destdir="dest" /></code>. If Ant finds a file
<code>src/a/b/C.java</code> it expects it to be in package
<code>a.b</code> so that the resulting <code>.class</code>
file is going to be <code>dest/a/b/C.class</code>.</p>
<p>If your setup is different, Ant's heuristic won't work and
it will recompile classes that are up to date. Ant is not the
only tool, that expects a source tree layout like this.</p>

<p>The last option is to use a scripting language to set the
properties. This can be particularly handy when you need much
better control than the simple conditions shown here, but of
course comes with the overhead of adding JAR files to support
the language, to say nothing of the added maintenance in requiring
two languages to implement a single system.</p>

<li>It is not complete - if you add new tasks via

<a href="http://www.sdv.fr/pages/casa/html/ant-dtd.en.html">this

is based on Ant 0.3.1.</li>
<li>It may even be an invalid DTD. As Ant allows tasks
writers to define arbitrary elements, name collisions will
happen quite frequently - if your version of Ant contains
the optional <code><test></code> and
<code><junit></code> tasks, there are two XML
elements named test (the task and the nested child element
of <code><junit></code>) with different attribute
lists. This problem cannot be solved, DTDs don't give a
syntax rich enough to support this.</li>

<p>There is a bug in the Solaris reference implementation of
the JDK, see <a href="http://developer.java.sun.com/developer/bugParade/bugs/4230399.html">http://developer.java.sun.com/developer/bugParade/bugs/4230399.html</a>.
This also appears to be true under Linux, moving the JDK to
the front of the PATH fixes the problem.</p>
