Use case
A handy option in Jira is to use issue keys in comments to reference them whenever needed. But as the amount of comments grow, it can get hard to keep track of all mentioned issues in the comments. Therefore, the following rule checks for issue keys being added to comments and automatically links them to the current issue.
Issue Commented event
Create a new rule and name it appropriately.
Providing a description will help you to identify what the rule does but this step is optional.
Add a trigger → Issue event → Issue Commented
No further configuration needed. The automation rule is triggered every time an issue is being commented.
Boolean condition
Add a Condition → Boolean Condition
Expression*
Use the following Parser Expression:
findPattern(%{trigger.issue.lastComment},"([A-Z][A-Z0-9]+)-\\d+") !~ null
Create issue link action
Next to the Boolean Condition click on Add → Action → Create issue link
Issue link type*
Choose relates to (Relates)
Issue selection*
Choose Issue List Expression
Use the following Parser Expression*:
issueKeysToIssueList(toString(findPattern(%{trigger.issue.lastComment},"([A-Z][A-Z0-9]+)-\\d+")))
