To make building Velocity easy and consistant, we have provided scripts
to build Velocity for both Unix and Windows. We use a Jakarta project
called Ant to perform the
build process and provide Ant with the distribution, so no external
build utilities are required.
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'.
On Unix, change to the build directory (
build). Then, build the Velocity jar via the build.sh
On Windows, change to the build directory
cd build). Then, build the Velocity jar via the
build.bat script :
Executing this script will create a bin directory
within the Velocity distribution directory. The bin
directory will contain the compiled class files (inside a
classes directory) as well as a
velocity-XX.jar file, where XX is the current
version number. Be sure to update your classpath to include Velocity's
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.)
If the problems persist, do not hesitate to ask the Velocity community
via our mail lists. They can be found here. Please read
