Existing Jenkins sites can no longer be synchronized or deleted after upgrading to version 2.3.4 of the add-on.
- When attempting to synchronize a site, a warning message is displayed "Unable to update the synchronization status for 'site name'."
- When trying to delete the site an error message is displayed "Unable to delete site 'site name'."
New sites added are not effected.
The root cause lies in the a bug in the way the cache is used to hold synchronization status of different Jenkins sites and jobs. - JJI-393Getting issue details... STATUS has been filed to address the root cause.
A workaround to this problem is to restart Jira, in case of a cluster it may require all nodes are restarted, to clear the cache. After the restart problems detailed above should be resolved.
