Issue Transition in Jira Cloud (ScriptRunner)

[Jon Hollister]

I'm having trouble finding simple issue transition code that actually functions in Jira Cloud. I'm trying to set up a ScriptRunner listener for issue updates.

When specific criteria are met (Through my own code logic, not transition validation which I know doesn't work in cloud) I'm trying to transition my issue status. No matter what I do though, I'm still getting the error 'unable to resolve class IssueService'.

Being on cloud, I can't import the proper packages, and I can't find a simple solution anywhere that fits my use case.  How can I actually use any of the IssueService methods, or what alternatives am I supposed to use in Cloud?

Thanks in advance.

Edit: Here's my code after much finagling.

def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
def issueManager = ComponentAccessor.issueManager
def issue = issueManager.getIssueObject(event.issue.key)
IssueService issueService = ComponentAccessor.getIssueService()
def actionId = 10017 //Transition ID
def customFieldManager = ComponentAccessor.getCustomFieldManager()

if (issue.getStatus().name == "Unassigned" && issue.getAssigneeUser() != null) {
    transitionResult = issueService.transition(currentUser, transitionValidationResult)
    //Find docs for transition, replace transitionValidationResult

    if (transitionResult.isValid()) {
        log.debug("Transitioned issue $issue through action $actionId")
    }
    else {
        log.debug("Transition result is not valid") 
    }
}

Post your script. Doing what you describe is possible with SR on Jira Cloud.

Updated the top post. I haven't been able to test it at all, because it keeps failing at line 8, unable to resolve class.

IssueService issueService = ComponentAccessor.getIssueService()

Those classes aren't available via Cloud.  You'll want to use the supplied binding and hit the API directly or everything else.

// use issue.fields to read your issue fields and check that you hit your condition

 logger.info(issue.fields)

// call the transitions endpoint to execute the transition
