How to automate task creation under an epic using scriptrunner, when a custom field is updated ?

The scenario I'm trying to achieve is as given below : 

Step 1 : Create epic.

Step 2 : using the multi-select custom field "task creator", select the applicable values [can be Backend, andriod, web, QA, etc].

Step 3 : Tasks for the values selected/checked must get created under the epic.

Note 1 : The value selected might be of different project than that of the epic. Ex : Epic might be of Development project, task might be of backend project.

Note 2 : The above mentioned scenario is to be acheived using script runner for JIRA cloud.

Any help is welcome.

Thanks in advance.

I think that this would be easier to accomplish using Automation for Jira. That said, it should be pretty straightforward. 

You can find example code for creating a sub-task here: Example Custom Scripts (

All you need to do is to start by getting the value of the "task creator" field and then loop through the create sub-task code for each selected value. 

I can't provide the code for you since this is a service that we provide to our clients. If you have groovy and REST experience, you should be able to figure it out from the example.
