How to populate END date automatically

[Musku Nagaraju]

Hi Team,

I am trying to populate a Date field by Adding days to another date field value.

Consider, there are two date fields "Start Date" & "End Date" and a numeric field "Number Field" for days.

Required Output : End Date = Start Date+NumberField

 How can I achieve this with the groovy script?

I used the below code but getting below error, Please help me on this.

Issue issue = issue
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def daysToAddCF = customFieldManager.getCustomFieldObjectByName("Duration")
def dateACF = customFieldManager.getCustomFieldObjectByName("StartDate")

def dateAValue = issue.getCustomFieldValue(dateACF) as Date
def daysToAdd = issue.getCustomFieldValue(daysToAddCF) as int
def EndDate = Calendar.getInstance()

EndDate.setTime(dateAValue)
EndDate.add(Calendar.DATE, daysToAdd)
return EndDate.getTime()

Hi Musku,

I am not familiar with Groovy, but it can easily be done with an Automation For Jira rule.

Hi John,

Thanks for you quick respond, yes, but I am looking to get this fields should be populate automatically in create screen like End Date = Startdate=Duration .

With help of automation we can get that field create automatically once issue has been created.

Thanks
