Using ScriptRunner Post Function to set issue custom date based on other custom date field

JIRA Version: v6.3.15 (JIRA Server)

Script Runner Version: 3.0.16

My Objective -

Add 1278 days (30 months) to a datepicker custom field "DateCF1" and store it to another custom date field, "DateCF2" with a post function. I don't want to change DateCF1, it is just the starting date for DateCF2.


I've "found" multiple solutions to this problem, none of which have worked. I don't know what I'm doing wrong.

I don't want to use a scripted field, as I'd like the project administrators to have the ability to edit DateCF2 after the transition, as needed.

My current approach has been "Add post function" -> "Script Post-Function" -> "Custom script post-function" -> "Inline script" ->

def dateField = getCustomFieldValue("DateCF1")
def number = 1278

result = dateField + number
setCustomFieldValue("DateCF2",new Date(result.getTime()))

Any help at all would be sincerely appreciated.

I don't have access to the log as I'm not a server admin, so my trial and error has been publishing the workflow and moving through the transition. 

Thank you in advance,

Another option I ended up to set date +N working days:

import com.atlassian.jira.component.ComponentAccessor
import java.sql.Timestamp
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.CustomFieldManager
import java.time.LocalDateTime
import com.atlassian.jira.timezone.TimeZoneManager
import com.atlassian.jira.util.DateFieldFormat
import java.time.DayOfWeek;
int businessDayToSkip = 5

def cfm = ComponentAccessor.getCustomFieldManager()

def currentDueDate = cfm.getCustomFieldObjectsByName("Current Due Date").getAt(0)

def timeZoneManager = ComponentAccessor.getComponent(TimeZoneManager)
def dateFieldFormat = ComponentAccessor.getComponent(DateFieldFormat)
def loggedUserZoneId = timeZoneManager.loggedInUserTimeZone.toZoneId()

LocalDateTime localDateTimeToSet = addWorkingDays(, businessDayToSkip)

issue.setCustomFieldValue(currentDueDate, Timestamp.valueOf(localDateTimeToSet))

LocalDateTime addWorkingDays(LocalDateTime date, int workdays) {
if (workdays < 1) {
return date;

LocalDateTime result = date;
int addedDays = 0;
while (addedDays < workdays) {
result = result.plusDays(1);
if (!(result.getDayOfWeek() == DayOfWeek.SATURDAY ||
result.getDayOfWeek() == DayOfWeek.SUNDAY)) {

return result;

If anyone runs into a similar issue... I ended up just using the due date and not a custom field. I don't know what the syntax problem was but I gave up and just went a different direction.

This is something that finally works and relatively meets my needs:

import com.atlassian.jira.component.ComponentAccessor

def customFieldManager = ComponentAccessor.customFieldManager
def cfSD = customFieldManager.getCustomFieldObjectByName("Start Date")
def cfCT = customFieldManager.getCustomFieldObjectByName("Cycle Time")
def vCT = issue.getCustomFieldValue(cfCT) as Integer
def dateField = issue.getDueDate()

if (vCT != 0) {
if (dateField) {

result = dateField + 1
Calendar c1 = GregorianCalendar.getInstance();

while (vCT != 0) {
result = result - 1
while (c1.get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY || c1.get(Calendar.DAY_OF_WEEK) == Calendar.SUNDAY) {
result = result - 1
vCT = vCT - 1

issue.setCustomFieldValue(cfSD, result)

I suspect it's working, but adding 1278 milliseconds to the date is not changing it enough for Jira to display any difference.

I still have found no solution to this.

I know there has to be some easy answer, but I can't seem to take a custom date field, add/subtract days to it, and then store that in another custom field.

Any help would be appreciated
