How do I add a due date to a ticket that wasn't created with one?

[Sam]

I'm trying to add a due date to a ticket in Script Runner via a listener and absolutely none of the documentation has been helpful. This all I have so far:

import java.sql.Timestamp;

def issue = event.getIssue();
def dueDate = new Date(System.currentTimeMillis() + 7*24*60*60*1000);
//issue.dueDate.setDate(new Date(System.currentTimeMillis() + 7*24*60*60*1000))
issue.dueDate.setTime(System.currentTimeMillis() + 7*24*60*60*1000)

The goal is to add a due date that is exactly one week after the ticket was created. Can someone please help?

Edit: Also, is there an online textbook or manual where it's explained how to create a custom field? I'm new at this, and I can't find anything like that yet.

Hi @Sam ,

In your Listener make sure the Event to listen to is Issue Created

Here's the working script:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption

def issueManager = ComponentAccessor.getIssueManager();
def issue = event.getIssue();
issue.setDueDate(new Timestamp((new Date() + 7).time))
def currentUserObj = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
issueManager.updateIssue(currentUserObj, issue, EventDispatchOption.ISSUE_UPDATED, false)

Hi Bryan,

Thank you for the quick response! However, when I copy and paste the code into the listener, I get the error "unable to resolve class Timestamp" at the line 

issue.setDueDate(new Timestamp((new Date() + 7).time))

 Do you know why this might be happening?

Hi @Sam ,

Oh right try to import the class at the top.

import java.sql.Timestamp

If there are errors, just ignore it and let the script run, i just tested it earlier.

Thanks, Bryan! I just tried it, and it worked!
