Symptoms

 |  |
Environment
Jira Data Center on any version
Cause
This problem is caused due to customization in the velocity.properties file, for example, to use custom velocity templates. In the latest Jira releases, the velocity.properties file has changed in comparison with older ones. Hence, when bringing over the configuration from the older version to the new install Jira breaks due to the difference between the versions.
Resolution
In order to fix this issue, please follow the steps below:
- Shutdown Jira
Replace the
velocity.propertiesfile inside the$JIRA-INSTALL/atlassian-jira/WEB-INF/classes/directory with the original file
If you are running a different version of JIRA you will need to manually extract this file from a newly downloaded installation ZIP.Restart Jira
If needed, it is still possible to customize the file, just be sure to customize the one bundled with the application.
