How to copy Watchers and comments in script post-function

[Jeremy Schrecengost]

Hello,

I have a script post-function that will copy an issue to a new project on transition based on some variables. 

I added in some Additional Issue Actions in (copying the issue assign) using this code

issue.assignee = sourceIssue.assignee

Is there a way to copy over comment or more importantly watchers? I have tried issue.watchers but that is not a valld data source for issue

If there is not a way can I get a list of the functions for the issue (like a wiki)

I CANNOT install any additional add-ons we have a locked environment, I can only use scriptRunner or default JIRA functionality

Here is a draft for you. Initilise varialbles issue and source issue properly

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.comments.Comment
import com.atlassian.jira.issue.comments.CommentManager
import com.atlassian.jira.issue.watchers.WatcherManager

Issue issue
Issue sourceIssue

WatcherManager watcherManager = ComponentAccessor.getWatcherManager();
watcherManager.startWatching(watcherManager.getWatchers(sourceIssue, null), issue);

CommentManager commentManager = ComponentAccessor.getCommentManager();

for(Comment comment: commentManager.getComments(sourceIssue)){
    commentManager.create(issue, comment.authorApplicationUser, comment.body, false)
}

I am having 2 issues with this code.

The first one is I am getting an error on this line

watcherManager.startWatching(watcherManager.getWatchers(sourceIssue, null), issue);

Also I tried to remove the watchers section and just use the comment section and I am not getting any errors in the code but the copy and everything is failing. Since I do not have any logging setup I do not know the reason for the fail. 

Also I am on JIRA v6.3.12 if that changes anything

Hm, try this one

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.comments.Comment
import com.atlassian.jira.issue.comments.CommentManager
import com.atlassian.jira.issue.watchers.WatcherManager
import com.atlassian.jira.user.ApplicationUser

Issue issue 
Issue sourceIssue

WatcherManager watcherManager = ComponentAccessor.getWatcherManager();
for(ApplicationUser user: watcherManager.getWatchers(issue, Locale.FRANCE))    
    watcherManager.startWatching(user, issue);

CommentManager commentManager = ComponentAccessor.getCommentManager();
for(Comment comment: commentManager.getComments(sourceIssue)){
    commentManager.create(issue, comment.authorApplicationUser, comment.body, false)
}

I have tried to use the following (Tested via Script Console)

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.comments.Comment
import com.atlassian.jira.issue.comments.CommentManager
import com.atlassian.jira.issue.watchers.WatcherManager

//Issue issue
//Issue sourceIssue

Issue sourceIssue = ComponentAccessor.getIssueManager().getIssueObject("SUP_TR_NOTIFY-1")
Issue issue = ComponentAccessor.getIssueManager().getIssueObject("SUP_TR_NOTIFY-2")

WatcherManager watcherManager = ComponentAccessor.getWatcherManager();
watcherManager.startWatching(watcherManager.getWatchers(sourceIssue, null), issue);

And the error is :
