Create linked issue from remote issue hyperlink

[Samuel Burchmore]

I have 2 JSM instances connected with OAuth.

On the first instance, I have a text field which stores a hyperlink to another issue on the second JSM instance. I'm trying to write a script which automatically creates a reciprocal link between the 2 issues.

My understanding so far is -

1. I need to write a rest api call which creates the link on the remote issue using the local issues information.
2. Retrieve the remote issues information and use that to create a reciprocal link on the local instance.

I've cobbled this script together based on similar questions here -

import groovy.json.JsonBuilder

import static com.atlassian.sal.api.net.Request.MethodType.POST

import com.atlassian.jira.component.ComponentAccessor

def appLinkService = ComponentLocator.getComponent(ApplicationLinkService)

def appLink = appLinkService.getPrimaryApplicationLink(JiraApplicationType)

def applicationLinkRequestFactory = appLink.createAuthenticatedRequestFactory()

def user = Users.getByName("<admin username>")

def customFieldManager = ComponentAccessor.getCustomFieldManager()

def customField = customFieldManager.getCustomFieldObject("customfield_<custom field id>")

// get hyperlink from current ticket

def remoteIssueLink = issue.getCustomFieldValue(customField) as String

def localIssueLink = ("<local link>" + issue.getKey())

def remoteIssueKey = remoteIssueLink.split("/").last()

// create post call for remote ticket

def post = ("/rest/api/2/issue/" + remoteIssueKey + "/remotelink")

// create input for remote post call

def input = new JsonBuilder([

    object: [

        url: localIssueLink,

        title: issue

        ]

]).toString()

// define request

def request = applicationLinkRequestFactory.createRequest(POST, post)

    .addHeader("Content-Type", "application/json")

    .setEntity(input)

// make request and store response

def responseContentJson

request.execute(new ResponseHandler<Response>() {

    @Override

    void handle(Response response) throws ResponseException {

        responseContentJson = response.responseBodyAsString

        if ( response.statusCode != 201) {

            issue.addComment("Fail: ${response.responseBodyAsString}")

        }

    }

})

// instantiate remote issue link builder

def linkBuilder = new RemoteIssueLinkBuilder()

// populate link builder with remote issue detals

linkBuilder.url(remoteIssueLink)

linkBuilder.title(remoteIssueKey)

linkBuilder.issueId(issue.id)

// create link

def remoteIssueLinkService = ComponentAccessor.getComponentOfType(RemoteIssueLinkService.class)

def validationResult = remoteIssueLinkService.validateCreate(user, linkBuilder.build())

remoteIssueLinkService.create(user, validationResult)

When I run this script I encounter a stack overflow. I'm really quite new to scriptrunner and the rest API. My understanding is poor and I'm struggling to understand whats going wrong.

Hi @Samuel Burchmore

This is an interesting challenge. Have you considered using Automation for Jira and the Jira DC API instead of a Groovy-scripted solution?

While it might take me a considerable amount of time to test this (right now I've only 1 Jira DC test instance available also), I'm thinking about something as described below:

• Trigger: issue created, field value changed, or scheduled backfill.
• Condition: the "remote-key" (let's call it that way) custom field is not empty and matches your expected key pattern/structure.
• Send a web request: GET the remote issue from instance B to confirm the specified key exists.
• Send a web request: POST the remote link to instance A.
• Send a web request: POST the reciprocal remote link to instance B.
• Add an audit comment, label, or issue property only if you need traceability.

I'd like to hear your thoughts or maybe an alternative solution that other members can describe or even test.

(I might not be fully right in my approach, so feel free to discuss any correction or improvement)
