Cause
The error indicates that the Lucene index is for a version that is not compatible with the current version of JIRA. This can happen during an upgrade or downgrade as the index files within $JIRA_HOME/caches/indexes/ are for a different version.
Resolution
Here are the following steps on how to fix this problem:
- Stop JIRA.
- Remove all the contents from under the JIRA index directory, which is typically
$JIRA_HOME/caches/indexes/. - Restart JIRA.
- Perform a full re-index via
Administration >> System >> Indexing.
The indexing process will require downtime, so it is advisable to run this after operation/office hours or during the weekends.
