Stash comes with case insenitivity on jira matching. Very annoying if you’re lazy ;). Luckily there is a way to change this… however there was an undocumented change in Stash 2.8 that caused things to stop working.
Previously if you had wanted case insensativity:
JVM_SUPPORT_RECOMMENDED_ARGS="-Dstash.jira.key.pattern=\"((?<!([A-Za-z]{1,10})-?)[A-Za-z]+-\d+)\""
Stash 2.8+
JVM_SUPPORT_RECOMMENDED_ARGS="-Dintegration.jira.key.pattern=\"((?<!([A-Za-z]{1,10})-?)[A-Za-z]+-\d+)\""
Seems like Atlassian updated their documentation after we contacted them. Cheers guys!
