How do I remove a component value from a jira issue using Scriptrunner listener?

[Patrick Rach]

I am wondering if anyone has any code or gotten code to work through a scriptrunner listener to remove a particular component value on an Issue Created event.

I created an Issue Updated event listener to clone an epic with its stories. The trigger will be to add a Component of Clone Epic. Well I want to create another listener based on Issue Created event to remove the Clone Epic component from the newly created Epics.

Any advice is welcome.

Thank you in advanced!

I was able to accomplish this by using labels and creating two behaviors. First Behavior looks at the Issue_Updated Event and adding the label Clone_Epic. Upon adding this label, it clones the epic with the stories and subtasks.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.*
import com.atlassian.jira.event.*
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.issue.label.*
import org.apache.log4j.Logger

def loggedInUser = ComponentAccessor.jiraAuthenticationContext.loggedInUser
def customFieldManager = ComponentAccessor.customFieldManager
def issueManager = ComponentAccessor.issueManager
def issueLinkManager = ComponentAccessor.issueLinkManager
def issueFactory = ComponentAccessor.issueFactory
def subtaskManager = ComponentAccessor.subTaskManager

//def issue = issueManager.getIssueByCurrentKey('CPSPLAT-1698')

Issue issue = event.issue
def changeHolder = new DefaultIssueChangeHolder()
LabelManager labelManager = ComponentAccessor.getComponent(LabelManager);
def labels = labelManager.getLabels(issue.id) as String[]
def value = labels.find {it == /Clone_Epic/}

//Create a clone of an issue

static Issue clonedIssue(Issue issue, ApplicationUser loggedInUser, IssueFactory issueFactory, IssueManager issueManager) {

    def cloneIssueFactory = issueFactory.cloneIssue(issue)
    cloneIssueFactory.setCreated( new Date(System.currentTimeMillis()).toTimestamp() )
    def newIssueParams = ['issue': cloneIssueFactory] as Map<String, Object>
    issueManager.createIssueObject(loggedInUser, newIssueParams) 

}

def epic

if (issue.issueType.name == 'Epic' && value)  {

    //Cloning of the Epic

    def epicClone = clonedIssue(issue, loggedInUser, issueFactory, issueManager)
    epic = issueManager.getIssueByCurrentKey(epicClone.key)
    def epicName = customFieldManager.getCustomFieldObjectsByName('Epic Name').first()
    def originalEpicName = issue.getCustomFieldValue(epicName)
    epicName.updateValue(null, epic, new ModifiedValue(epic.getCustomFieldValue(epicName), "${originalEpicName} Clone".toString()), changeHolder)
    issueManager.updateIssue(loggedInUser, epic, EventDispatchOption.ISSUE_UPDATED, false)

    //Extraction of Original Issue(s) from Original Epic

    def links = issueLinkManager.getOutwardLinks(issue.id)
    def originalIssuesInEpic= links.findAll { it.issueLinkType.name == 'Epic-Story Link' }*.destinationObject

    //Cloning of Original Issue(s) from the Original Epic and Adding it to the Cloned Epic

    originalIssuesInEpic.each {

        def clonedIssue = clonedIssue(it, loggedInUser, issueFactory, issueManager)
        def subtasks = it.subTaskObjects

        if (subtasks) {

            subtasks.each {subtask ->

                def mutableSubtask = subtask as MutableIssue
                def toClone = issueFactory.cloneIssue(mutableSubtask)
                mutableSubtask.setCreated(new Date(System.currentTimeMillis()).toTimestamp())
                def cloned = issueManager.createIssueObject(clonedIssue.reporter, toClone)
                subtaskManager.createSubTaskIssueLink(clonedIssue, cloned, clonedIssue.reporter)

            log.warn(subtask.key)

            }

        }

        def targetField = customFieldManager.getCustomFieldObjects(clonedIssue).findByName('Epic Link')
        targetField.updateValue(null, clonedIssue, new ModifiedValue(clonedIssue.getCustomFieldValue(targetField), epic), changeHolder)

        }

    }

return epic

After this, I wanted to remove the Clone_Epic label from the cloned epics to avoid duplications when updates are made on the newly created Epics. So, I added another listener at the Issue_Created Event and I got my desired end result. Here is the code here:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.*
import com.atlassian.jira.event.*
import com.atlassian.jira.issue.label.LabelManager

def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
def issueManager = ComponentAccessor.issueManager
Issue issue = event.issue
LabelManager labelManager = ComponentAccessor.getComponent(LabelManager)
def labels = labelManager.getLabels(issue.id).collect{it.getLabel()}
labels -= 'Clone_Epic'
labelManager.setLabels(user,issue.id,labels.toSet(),false,false)
