How to copy an Attachment from a screen in subtask to the main Issue

[SergioCourtois]

Hello everyone! I'm trying to copy an attachment from a screen ,
Who is associate to the closure of  a subtask .

I succeeded to do it with comment :

def commentManager = ComponentAccessor.getCommentManager()
def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
def originalComment = transientVars.comment as String
def comments = originalComment
if (comments!=null) 
{
    commentManager.create(parentIssue, user, comments, false)         
}

I'm trying to do an equivalent with the attachement ( 
copyAttachments(Issue issue, ApplicationUser author, String newIssueKey)
) but

transientVars.attachment

Does not seem to exist
How am I supposed to do ?

Hi Sergio,

Based on your description, the attachment added during the 'Close issue' transition is always the last one (unless you have any post functions/automation that adds more attachments after that), the code to copy it to the parent issue is as follows:

import com.atlassian.jira.component.ComponentAccessor

def attMgr = ComponentAccessor.getAttachmentManager()
def attachments = attMgr.getAttachments(issue)
def lastAtt = attachments[0]
def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
 
if (attachments.size() > 1){
  for (int i = 1; i < attachments.size(); i++){
    if (lastAtt.getCreated().getTime() < attachments[i].getCreated().getTime()){
      lastAtt = attachments[i]
    }
  }
} 

attMgr.copyAttachment(lastAtt, currentUser, issue.getParentObject().getKey())

 Also, make sure that you place this post function AFTER the "Re-index an issue to keep indexes in sync with the database" post function

Hi Sergio,

I would like to do the exact same thing but have no idea on how to manage that.

Hope someone could help :)

Best regards,

Germain.

I am also trying to copy the last attachment during a post function by groovy. You did it?
