Atlassian does not support customisations to Velocity templates or other JIRA files. For more information about Atlassian support, see Atlassian Support Offerings.

Deploying Velocity Templates without a Restart

In a development instance, you can play with picking up velocity file changes without a restart.
From <jira-install>/atlassian-jira/WEB-INF/classes/velocity.properties:

  1. Change class.resource.loader.cache from true to false
  2. Uncomment (remove the # sign from) #velocimacro.library.autoreload=true

Keep in mind that the next time you upgrade JIRA – or need a new installation for any reason – you will have to manually copy any changes you have made to the JSPs or tempates into the new installation of JIRA. If the JSPs or templates have changed in the newer version, you will have to port your customization into them.
