Automating link creation between subtasks by linking to next subtask each time upon creation

VVC

Would it be possible to automate the linking of subtasks upon creation regardless of tickets created in out of order within one Jira project?

 

The expectation on the automation or scripting is to retrieve all the subtasks then sort by either creation date/time or issue key or any parameter that fits best under the parent issue and then looping through the results to link one subtask ticket to the immediate next one.

One possible solution is to create the link as the subtasks are created, using an Automation rule.

Trigger: issue created

Condition: Issue type is sub-task

Action: Lookup Issues
Use a JQL to find all the subtasks under the same parent, excluding the current subtask, and order by the parameter you choose so that "last" one to which you would want to link the new subtask would be at the top of the list

key != {{triggerIssue.key}} and parent={{triggerIssue.parent.key}} order by created desc

Action: Edit Issue
Edit the newly created subtask. Add the Linked Issues field. Choose your link type (i.e. depends on). To link to the issue that appears first in the list of issues returned by the Lookup enter the smart value {{lookupIssues.first.key}}
