<p>
Velocity runs on a variety of platforms that have installed the Java 2
Virtual Machine. The J2SDK is required for users who want to compile
Velocity from its source code.
</p>
<p>
Everything required to build Velocity comes with the distribution, which
can be obtained from <a href="http://jakarta.apache.org/getinvolved/cvsindex.html">CVS</a> or
from the <a href="http://jakarta.apache.org/builds/jakarta-velocity/nightly/">nightly
builds</a>. However, you will need to install Ant, an excellent
Java-based build tool. Ant is also a Jakarta project, and can be
found <a href="http://jakarta.apache.org/ant/">here</a>.
</p>
<p>
The directory tree of the distribution looks like :
</p>
<div align="left">
<table cellspacing="4" cellpadding="0" border="0">

<p>
To make building Velocity easy and consistant, we require a Jakarta project
called <a href="http://jakarta.apache.org/ant/">Ant</a> version 1.3 or
higher to perform the build process. We assume that you have followed
Ant's installation instructions and have it properly installed. It's not
difficult, and I think that you will find it an excellent addition to
your programmer's toolbox.
</p>
<p>
In each case below, it is assumed that you were successful in getting
the distribution from CVS or as a nightly build, and with the latter,
were successful in unpacking. Also, it is assumed that you are starting
in the 'jakarta-velocity' directory, the root of the distribution tree.
All directory references will be relative to 'jakarta-velocity'.
</p>
<p>
Change to the <filename>build</filename> directory (<code>cd
build</code>). Then, to build the jar file, simply type:
</p>
<div align="left">
<table cellspacing="4" cellpadding="0" border="0">

</table>
</div>
<p>
Executing this script will create a <filename>bin</filename> directory
within the Velocity distribution directory. The <filename>bin</filename>
directory will contain the compiled class files (inside a
<filename>classes</filename> directory) as well as a
<filename>velocity-XX.jar</filename> file, where XX is the current
version number. Be sure to update your classpath to include Velocity's
<filename>.jar</filename> file.
</p>
<p>
Note that to build any of the specific build targets, as detailed in
the <a href="developer-guide.html">developers guide</a>, simply add
the target name to the command line. For example, to build the Javadoc
API documentation :

<div align="left">

</div>
<p>
Velocity should build 'out of the box', independent of your classpath.
If you get an error building Velocity, try a different nightly build (as
sometimes we make a mistake and the CVS at the time of the nightly
snapshot isn't complete) or refresh from CVS (you might have gotten a
CVS snapshot while a developer was checking things in.)
</p>
<p>
If the problems persist, do not hesitate to ask the Velocity community
via our mail lists. They can be found <a href="http://jakarta.apache.org/site/mail.html">here</a>. Please read
and understand the the guidelines for participating in any Jakarta mail
list.
