Building JIRA from source
One of the best things about JIRA, if you have a valid license, is that you get to see the source code. You can see it, modify it, break it… err? In this recipe we will modify it, because you have the license to do it!
Getting ready
Following are some of the prerequisites prior to building JIRA from the source:
A valid JIRA license to get access to the source code.
An environment with JDK 1.5 or higher for JIRA 4.2 and lower versions. JDK 1.6.x is required for JIRA 4.3 and above versions.
You will need both Maven 1 and Maven 2 if you are building versions prior to JIRA 4.3. Download Maven version 1.0.x and 2.1.x from http://maven.apache.org/. JIRA 4.3 and above versions only need Maven 2.1.0.
Note
You need both Maven 1 and Maven 2 for versions prior to JIRA 4.3, because Maven 1 is required to build the JIRA source and Maven 2 is required to build plugins for JIRA. JIRA has bundled plugins that need to be built along with JIRA, and so Maven 2 is also a must.
Maven 2.1.0...
