Copy attachments between 2 issue on different projects

[Claire Berry]

I have set up a global automation to copy attachments between 2 types of issues on 2 different projects.

When an attachment is added to the issue in project A, I want the attachment to copy over to the linked issue on project B.

The issue I am having with the automation is that it is duplicating the attachments.

For example, let's say I add one attachments image1.png to the issue in project A. This attachment then gets copied to the linked issue in project B (correct).
Then I add another attachment image2.png to the issue in project B.
But instead of just image2.png copying over to the issue in project A, both image1.png AND image2.png copy over.
So I end up with duplicate attachments on the issue in project A: image1.png, image1.png, image2.png.

Can anyone help configuring what I am trying to achieve here? I only want to copy over the new attachment added, not all existing attachments. 

Here is the automation:

Ended up getting this working with a custom script (thanks Scriptrunner!)



Full script here:

import com.atlassian.jira.component.ComponentAccessor

def attachmentManager = ComponentAccessor.attachmentManager

def user = Users.getByName('Automated-Jira-User')

def linkedIssues = ComponentAccessor.getIssueLinkManager().getLinkCollection(issue, user).getAllIssues()

def redirectedIssue

// Get the redirected linked issue

linkedIssues.each {

    if(it.getLabels().toString().contains('ukisr-redirected-ticket') || it.getIssueType().name == 'Software Project Redirect v2' || it.getIssueType().name == 'Software Project Redirect - 1 approval'){

        redirectedIssue = it

    }

}

if(!redirectedIssue){ return }


// Get current attachments for both issues

def attachments = issue.attachments

def redirectedAttachments = redirectedIssue.attachments

def redirectedAttachmentsFileNames = []

// Get all file names for attachments in linked issue to compare later

redirectedAttachments.each{ redirectedAttachment ->

    redirectedAttachmentsFileNames += redirectedAttachment.filename

}

attachments.each { attachment ->

    // If attachment doesn't already exist on linked ticket, add it

    if(!redirectedAttachmentsFileNames.contains(attachment.filename)){

        // log.warn('attachment not on linked issue')

        attachmentManager.copyAttachment(attachment, user, redirectedIssue.key)

    }

}

I went with a simpler solution to this problem.

There is a delete all attachments function. So I just delete all the attachments and copy them back again to get round this whenever an issue has its attachment field edited.

Watching this I have some suggestions on the cloud that I have checked on, not for the DC/Server.
