add (calender days) to date using script runner

I am trying to create custom scripted field using script runner to calculate the end dates

But got stuck here.

below is my code

import com.atlassian.jira.issue.MutableIssue
import java.sql.Timestamp;
MutableIssue myIssue = issue;
def dateField = getCustomfieldValue("Date")
Calendar dateField = Calendar.getInstance()
def numberfield = getcustomFieldValue("Days")
def number = numberfield?.intValue()

if number (!number || !dateField)
dateField.add(Calendar.DATE, number)
while ([Calendar.SATURDAY, Calendar.SUNDAY].contains(dateField.get(Calendar.DAY_OF_WEEK))) {
    def dateField.add(Calendar.DATE,number)
def result =  new Timestamp(dateField.gettime())
return new Date(result.gettime())

Hey Amar,

I thought that what you wanted was related to your last question here (, if not please let me know in order to delete it. You can try this part of code (I left in purpose the variable types). Of course there is room for optimisation.

import java.sql.Timestamp

Timestamp dateField = (Timestamp) getCustomFieldValue("DateCF")
long numberField = (long) getCustomFieldValue("NumberCF")

if (numberField == null)

int number = numberField.intValue()

if (dateField) {
    Date result = dateField;
    Date newDate = new Date(result.getTime())
    int i = 0 ;
    while (i < number) {

        result = result + 1
        newDate = new Date(result.getTime())
        if (newDate[Calendar.DAY_OF_WEEK] == Calendar.SATURDAY || 		 newDate[Calendar.DAY_OF_WEEK] == Calendar.SUNDAY) {
            number ++;

        i ++;
    return newDate




Is there a manual.. or a reference guide where i can learn this... Because every time getting stuck with new problem

Amar, I suppose what you mean is to learn how to write scripts. There is plenty of documentation in the web. Especially for the script runner there are a lot of examples in the documentation What I can advise you is to keep practicing. Regards, Thanos

Thanks a ton..for the code and prompt response
