ScriptRunner Post-function add 1 month to date field and update date field

[Chris Ghazanchian]

I would like to add 1 month to a custom date field (Next Cycle Date) and then update that date field upon a workflow transition (post-function).

I have the current script but it's not doing anything, not sure what I am doing wrong.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.UpdateIssueRequest
import java.text.SimpleDateFormat

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()

SimpleDateFormat dateFormatter = new SimpleDateFormat("dd/MMM/yy");
java.sql.Timestamp nextCycleDate = (java.sql.Timestamp)issue.getCustomFieldValue(customFieldManager.getCustomFieldObject("customfield_10603")) //get current "next cycle date"

nextCycleDate.setMonth(nextCycleDate.getMonth() + 1) //add 1 month to current cycle date to get next cycle date

issue.setCustomFieldValue(customFieldManager.getCustomFieldObject("customfield_10603"), nextCycleDate) //update next cycle date

Shoot, I thought I had commented out "<?xml version="1.0" encoding="ISO-8859-1"?>" in the other templates, but I hadn't of course... :-p

It's working like a charm now!

Yes, that was the problem. (Your XML was not well formatted.)

I've found a couple of differences in some of the other templates.
I think

$issues.get(0).project.key

could be the cause of the error - anye ideas? If anyone have a different method, that will of course do... :)
