Jira Groovy how to substract days from given date

Question

Hi,

I have a target date, which I needs to reduce 2 days during the transition. How I can do it using postfunction.

My target date 10/1/2019 so I would like to set 9/29/2019.

I am getting the value of target date by

def TD = customFieldManager.getCustomFieldObjectByName("Target Date")
def TDV = issue.getCustomFieldValue(TD)

but unable to subtract it. How I can do that? Any advise.

Thanks,

Om

I made a typo, should be

issueManager.updateIssue(...

not unpdateIssue, but anyway, if this postfunction is first in list (before the one that stores issue to db) you don't need to manually update it

@Ilya TurovIt doesn't work but I did by converting to date and string as below.

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

def currentUser = ComponentAccessor.jiraAuthenticationContext.loggedInUser

def TD = customFieldManager.getCustomFieldObjectByName("Target Date")
def TDV = issue.getCustomFieldValue(TD)

Date newTDV = (Date)TDV
def newDateformat = newTDV.format('MM/dd/yyyy')
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");

cal.setTime(sdf.parse(newDateformat));
cal.add(Calendar.DATE, -2);

Timestamp DefTDD = new Timestamp(cal.getTimeInMillis())

issue.setCustomFieldValue(TD, DefTDD)
issueManager.updateIssue(user, issue, EventDispatchOption.ISSUE_UPDATED ,false)

try something like this, iirc you can just subtract a number from timestamp and groovy will understand

last piece is for updating issue, though if it's a postfunction last line is not necessary

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

def currentUser = ComponentAccessor.jiraAuthenticationContext.loggedInUser
def TD = ComponentAccessor.customFieldManager.getCustomFieldObjectByName("Target Date")
def TDV = issue.getCustomFieldValue(TD)
TDV -= 2
issue.setCustomFieldValue(TD, TDV)
ComponentAccessor.issueManager.unpdateIssue(currentUser, issue, EventDispatchOption.ISSUE_UPDATED, false)
