Copy attachment with issue link in two project

[Andrey Miranda Diaz]

Can you help us with the following requirement :

We are using the clone issue link to clone tickets through a transition.

After cloning the ticket, it is required that the comments and attachment can be sent in both directions.

You can also synchronize attachments when they are added to comments .

I am trying with the following script by placing a code in script runner in a listering that is activated when I add an attachment to the parent ticket but when I add a new attachment it duplicates the ones that have been sent previously .

import com.atlassian.jira.component.ComponentAccessor

import com.atlassian.jira.issue.Issue

import com.atlassian.jira.issue.link.IssueLink

import com.atlassian.jira.event.type.EventDispatchOption

import com.atlassian.jira.issue.MutableIssue

import com.atlassian.jira.event.issue.IssueEvent

import com.atlassian.jira.issue.MutableIssue

import com.atlassian.jira.issue.attachment.Attachment

import com.atlassian.jira.issue.AttachmentManager

import com.atlassian.jira.issue.comments.Comment

import com.atlassian.jira.issue.comments.CommentManager

import com.atlassian.jira.issue.link.IssueLinkManager

import com.atlassian.jira.issue.link.IssueLink

import com.atlassian.jira.user.ApplicationUser

import org.ofbiz.core.entity.GenericValue

import com.atlassian.jira.component.ComponentAccessor

import com.atlassian.jira.issue.Issue

//def attachmentManager = ComponentAccessor.getAttachmentManager()

//def lastAttachment = attachmentManager.getAttachments(issue).last()

//def issue = ComponentAccessor.getIssueManager().getIssueObject() //dummy issue - delete this

//String[] validLinkTypes = ["moved to", "cloned to"]

def linker = ComponentAccessor.getIssueLinkManager()

def commentMgr = ComponentAccessor.getCommentManager()

def issue = event.issue as MutableIssue

def project = issue.getProjectObject().getKey()

def attachmentManager = ComponentAccessor.getAttachmentManager()

def lastAttachment = attachmentManager.getAttachments(issue).last()

def issueLinks = linker.getOutwardLinks(issue.getId())

def subElements = issueLinks.findAll { it.issueLinkType.name.contains('cloned to') && it.issueLinkType.name.contains('moved to')

def newComment = event.getComment()

def originalAuthor = newComment.getAuthorApplicationUser()

def commentBody = newComment.getBody()

/*

subElements.each {

if( commentBody != "")

{

commentMgr.create(it.getDestinationObject(), originalAuthor, commentBody , false)

}

}*/

//subElements.each {

if(lastAttachment)

{

attachmentManager.copyAttachment(lastAttachment, originalAuthor, it.getDestinationObject().key)

}

//}

}

Do you have any suggestions on how to solve this requirement?
