Jira transition script to create multiple subtasks

[Khanh Nguyen]

Fairly new to Jira and looking for guidance and samples on how to accomplish the following:

In the 'parent' issue, I have a multiuser picker custom field. . .

Parent Issue = ISSUE1

Assisting participants = partuser1, partuser2, partuser3

In a transition step (post function) in the workflow, I would like to call a script that would iterate through the Assisting participants field and create a subtask for every Assisting participant identified in that custome field.

Subtask = ISSUE2

Assignee = partuser1

Subtask = ISSUE3

Assignee = partuser2

Subtask = ISSUE4

Assignee = partuser3

These subtasks will also carry forward some other fields from the parent issues as well.

We know that this can be done in an external process but it would be much cleaner if this can be done as part of the transition process in the workflow.

Any sample scripts or advice will be appreciated. Thanks!

There is a similar question that Jamie has already answered at https://answers.atlassian.com/questions/29809/workflow-post-function-creating-subtask-for-each-user-of-group

That question has every step of the exact question! Good one

Thanks a ton! This will definitely put us on the right track.

There is a new add-on Create Multiple Issues on Transition. It helps creating issues and assign them simultaneously https://marketplace.atlassian.com/plugins/com.sentinel.jira.plugin.jira-create-tasks-on-transition-plugin

Hi,

You could use the Script Runner plugin to achieve this easily. With this you only have to specify the fields for the new Sub-Task. But I'm not aware of what code you could use. In this I think @Jamie (the plugin owner) would be very helpful. People contact him here (If he doesn't appear on this question)
