How To Build POI

Installing Ant

The POI build system requires two components to perform a build. Ant and forrest.

Specifically the build has been tested to work with Ant version 1.5.3 and Forrest 0.4. To install these products download the distributions and follow the instructions in their documentation. Make sure you don't forget to set the environment variables FORREST_HOME and ANT_HOME. The ANT_HOME/bin directory should be in the path.

One these products are installed you will also need to download some extra jar files required by the build.

Library Location

Just pick the latest versions of these jars and place them in ANT_HOME/lib

Running the Build

On the first run the ant build system will download all the jars required by the project to build ant. If you're behind a firewall this may cause some problems. Should you need to it's possible to manually put the jars in the correct directories. These can be obtained from here:

JAR Location
/commons-logging/jars/commons-logging-1.0.1.jar lib
/log4j/jars/log4j-1.2.8.jar lib
/commons-beanutils/jars/commons-beanutils-1.6.jar src/contrib/lib
/commons-collections/jars/commons-collections-2.1.jar src/contrib/lib
/commons-lang/jars/commons-lang-1.0-b1.jar src/contrib/lib
/junit/jars/junit-3.8.1.jar lib
