JIRA failing to start, NoClassDefFound com/atlassian/jira/health/checks/database/MySqlJdbcUrlHealthC

[Paul_Hildebrandt]

I recently started having issues with JIRA redirecting all requests to '/secure/errors.jsp.' I'm not entirely certain what may have changed on the server that led to the issue because there are several things I use the server for. 

On investigation of the logs, I see that the below error and stack trace show up on startup. The strange thing is that my JIRA instance is configured to use postgres rather than mysql, so I'm not certain why it's trying to do a Mysql health check. 

I've tried deleting the '.bundled-plugins' and '.osgi-plugins' directories as recommended in other topics, but no luck. 

Can anyone point me in a direction of something to try next?

I ended up fixing it by backing up everything and then running the JIRA installer again as an upgrade. I had to reconfigure a few things, but now all is well.

Hi Paul,

Can you also try to manually rebuild the Jira index as per the resolution in the article below?

• Unable to Rebuild Jira Applications Indexes

Please let me know how that goes.

Regards,

Shannon

Thanks for the advice. Unfortunately, no dice. After the index rebuild I still saw the same error in the log and JIRA is still redirecting to /secure/errors.jsp.
