Versions prior to 3.5 require JDK 1.4+ ### Install Apache Ant The POI build system requires Apache Ant Specifically the build has been tested to work with Ant version 1.7.1. To install the product download the distribution and follow the instructions. Remember to set the ANT_HOME environment variable and add ANT_HOME/bin to your shell's PATH. ### Install JUnit Running unit tests and building a distribution requires JUnit.
