Issue matches JQL
Overview
The Issue matches JQL validator allows you to block a workflow transition if the issue doesn’t match the JQL query.
Configuration
Define the JQL query that has to be met by the issue in the JQL field (e.g. “type = Bug and Priority = Blocker”)
Define the text of the error message in the Error message text field (e.g. “The issue doesn’t contain any comments”)
Use cases
Escalation is available only for bugs with Blocker and Critical priority
