This document explains how to set up a development environment, including how to make a connection to the Pentaho Github repository, check out the Pentaho server platform projects, build them, and debug them using a standalone Java application server and an IDE. This document also describes the Pentaho repository structure and a number of build targets important to developing with Pentaho.
You are expected to have a fair amount of knowledge of your IDE (Eclipse or Intellij) and the Java programming language. If you intend to deploy the platform as a J2EE application, you will also need some experience with J2EE and application servers in general (though this guide only covers Tomcat). Apache Ant knowledge is a plus, but not required to complete these instructions.
If following these instructions fails to result in a working development environment, ask for help on the Pentaho forum. If you discover any errors or omissions in this guide, please email them to jmatzan at pentaho.com.
If you are new to the BI Platform, please take a moment to review the Pentaho coding standards guidelines before continuing.
