Can a postfunction create a task and then also subtasks to the task using scriptrunner

[Gregory Bowe]

I would like to create an Issue in a workflow postfunction, very simple.  However, I also want to create sub-tasks in the created Issue. Can that be done with scriptrunner or some other tool?

Create your subtask(s) like any other issue (setting the necessary attributes, such as issue type [a type that is a subtask]), and then use the following bit of coding to link it to its parent. I'm not sure that both are necessary; I used them both when I scripted subtask creation a while back.

While setting the subtask attributes, use the setParentObject() or setParentId() method: https://docs.atlassian.com/software/jira/docs/api/7.6.1/com/atlassian/jira/issue/MutableIssue.html#setParentObject-com.atlassian.jira.issue.Issue-

After creating the subtask issue, link it to its parent with the createSubTaskIssueLink() method in the SubTaskManger class: https://docs.atlassian.com/software/jira/docs/api/7.6.1/com/atlassian/jira/config/SubTaskManager.html

Yes, there are a number of tools you can add to Jira that can do this sort of thing.

A starter for Scriptrunner is probably https://library.adaptavist.com/entity/create-sub-tasks-when-an-issue-is-created - I usually steal that and extend it.  

If you do decide to do this with SR, then remember that you'll need to create the main issue first, then add sub-tasks to it later.  The parent issue needs to exist for the sub-tasks to be attached.

I mean, if you have a script that does this:

• Work out what issue to create and add it to a list
• Work out a list of sub-tasks and add them to the list
• Iterate through list creating them all

It is likely to fail.  Your script should be more:

• Work out what issue to create and create it
• Work out a list of sub-tasks and add them to the list to create in the next section, or just create them as you work each one out
