Easiest way to do this is to use the script-runner add-on to provide a "scripted field".

Or you'll have to write a small plugin to provide a field that does this.

I solved the issue by using IssueEvent api .

@EventListener
public void onIssueEvent(IssueEvent issueEvent) {
Long eventTypeId = issueEvent.getEventTypeId();
Issue issue = issueEvent.getIssue();
System.out.println("Issue object is : "+issue);
Collection<Version> versionCollection = issue.getFixVersions();
Date date = null ;
for(Version version : versionCollection){
date = version.getReleaseDate();
break;
}
System.out.println("Issue Realease date is : "+date);
// if it's an event we're interested in, log it
if (eventTypeId.equals(EventType.ISSUE_CREATED_ID)) {
log.info("Issue {} has been created at {}.", issue.getKey(), issue.getCreated());
System.out.println("Issue is created , issue key is :"+issue.getKey());
IssueManager issueManager = com.atlassian.jira.ComponentManager.getInstance().getIssueManager();
System.out.println("issueManager :"+issueManager);
CustomFieldManager cfManager = com.atlassian.jira.ComponentManager.getInstance().getCustomFieldManager();
System.out.println("cfManager :"+cfManager);
MutableIssue missue = issueManager.getIssueObject(issue.getKey());
System.out.println("MutableIssue :"+missue);
CustomField cf = cfManager.getCustomFieldObjectByName("MyMapDate");
System.out.println("CustomField :"+cf);
IssueChangeHolder changeHolder = new DefaultIssueChangeHolder();
System.out.println("IssueChangeHolder :"+changeHolder);

Calendar c = Calendar.getInstance();
c.setTime(date);
c.add(Calendar.DAY_OF_YEAR, 2);
Date dates = c.getTime();
cf.updateValue(null, missue, new ModifiedValue(missue.getCustomFieldValue(cf), ""+dates),changeHolder);
System.out.println("Updated date is :"+changeHolder.getChangeItems().get(0));
} else if (eventTypeId.equals(EventType.ISSUE_RESOLVED_ID)) {
log.info("Issue {} has been resolved at {}.", issue.getKey(), issue.getResolutionDate());
} else if (eventTypeId.equals(EventType.ISSUE_CLOSED_ID)) {
log.info("Issue {} has been closed at {}.", issue.getKey(), issue.getUpdated());
}
}
