Commercial users receive access to JIRA's source code. This topic explains how to build this source code back into a deployable JIRA application.
Building JIRA from source is only necessary if need to make modifications to JIRA's source code. You should not need to rebuild JIRA if:
- You need to change JSP files.
- Create a JIRA plugin that adds functionality to JIRA. For more information, read the JIRA Plugin Guide.
(Often, changes and enhancements to JIRA's functionality can be made via a JIRA plugin without requiring core JIRA source code modifications.)
