How to add watchers after creating an issue using groovy

[Vineela Durbha]

I am creating an issue using listener from one of the workflow transitions.

Now can one help with adding watchers to this newly created issue because we will not be having the issue key to be passed.

I want to add reporter from the parent issue to be copied to newly copied issue under watchers.

Hi,

May you try this code ?

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.user.ApplicationUser

def watcherManager = ComponentAccessor.getWatcherManager()
def issueManager = ComponentAccessor.getIssueManager()
def watchers = issueManager.getWatchersFor(issue.getParentObject())

for (ApplicationUser watcher:watchers){
watcherManager.startWatching(watcher, issue)
}

 Also make sure you are working on a sub-task to not get an error.

Actually I am trying to create a new ticket in different project from one of the transitions using Listener

So in your code issue refers to current issue rite?

[Antoine Berry]

Absolutely. "issue" is the subtask that is being created.

Do you need more help ?

How to get reporter value for the parent object. I am trying to copy reporter value of parent object to watchers in child.

Also this is not a sub task request. It is a new issue being created but not of the type sub task

[Antoine Berry]

Ah sorry, I thought you wanted to add all the watchers from the parent issue to the child issue.

Then this should work : 

import com.atlassian.jira.component.ComponentAccessor

def watcherManager = ComponentAccessor.getWatcherManager()

watcherManager.startWatching(issue.getParentObject().getReporter(), issue)

I tried with above code and I am getting below error

java.lang.NullPointerException: Cannot invoke method getReporter() on null object

This is because parent object is returning null. This is not a sub task being created . I am just clicking on one of the button on transition screen and new ticket in different project is being created

Hi, have you solved your problem ? 

If I understand correctly you need to retrieve the linked issue instead of the parent issue ?

[Vineela Durbha]

Yes i am looking for the linked issue only not the parent one..but here i m not trying to create any link..just i would be creating the ticket using listener from one of the transition screen..

So i am not finding a way to add watchers here because startwatching method is expecting issue as one of the parameter n I dont know how to pass that parameter

[Antoine Berry]

you could use the linkedIssue object depending on the link type (inwards or outwards) : 

import com.atlassian.jira.issue.link.IssueLink;
import com.atlassian.jira.component.ComponentAccessor;


List<IssueLink> allOutIssueLink = ComponentAccessor.getIssueLinkManager().getOutwardLinks(issue.getId());
for (Iterator<IssueLink> outIterator = allOutIssueLink.iterator(); outIterator.hasNext();) {
   IssueLink issueLink = (IssueLink) outIterator.next();
   def linkedIssue = issueLink.getDestinationObject()
}

List<IssueLink> allInIssueLink = ComponentAccessor.getIssueLinkManager().getInwardLinks(issue.getId());
for (Iterator<IssueLink> outIterator = allInIssueLink.iterator(); outIterator.hasNext();) {
   IssueLink issueLink = (IssueLink) outIterator.next();
   def linkedIssue = issueLink.getDestinationObject()
}

[Vineela Durbha]

But i am not trying to establish any link ..on clicking a transition screen ,issue in a different project gets created..i m not establishing any link

[Antoine Berry]

Well you said you are linking the two issues. In that case you can use 

watcherManager.startWatching(linkedIssue.getReporter(), issue)

If there is no link between the two issues, you cannot retrieve the "source" issue, unless you use a trick like storing the key in a custom field or something similar. I would strongly suggest to just create a link between the two issues though.
