Automatically delete sub-tasks

[Callum Carlile _Automation Consultants_]

I have a workflow that creates 5 different subtasks via different transitions. I have a global 'Cancel' transition to close the task on the parent workflow and all sub-task worflows.

I have this built-in code from Adaptavist:

import com.atlassian.jira.component.ComponentAccessor

def issueService = ComponentAccessor.getIssueService()
def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()

def subTasks = issue.getSubTaskObjects()
subTasks.each {
 if (it.statusObject.name == "Closed") {
 def issueInputParameters = issueService.newIssueInputParameters()
 issueInputParameters.with {
 setResolutionId(10301) // resolution of "Fixed"
 setComment("*Resolving* as a result of the *Resolve* action being applied to the parent.")
 setSkipScreenCheck(true)
 }

 // validate and transition subtask
 def validationResult = issueService.validateTransition(null, 10317, 41, issueInputParameters)
 if (validationResult.isValid()) {
 def issueResult = issueService.transition(user, validationResult)
 if (!issueResult.isValid()) {
 log.warn("Failed to transition subtask ${it.key}, errors: ${issueResult.errorCollection}")
 }
 } else {
 log.warn("Could not transition subtask ${it.key}, errors: ${validationResult.errorCollection}")
 }
 }
}

When I test it, nothing is working, and the logs in the post function say that there are no problems. I have searched the internet and the community questions high and low for an answer but have had no luck.

Please may someone help me with what values I need to enter and where, and if this will close all my subtasks or if i need to copy certain bits of code and reuse them for different subtasks

There is this code which is meant to work:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
// for JIRA v6.*
def user = ComponentAccessor.getJiraAuthenticationContext().user.directoryUser
// for JIRA v7.*
// def user = ComponentAccessor.getJiraAuthenticationContext().user
def issueManager = ComponentAccessor.getIssueManager()
// will return a Collection<Issue> with all the subtasks of the current issue
def subTasksList = issue.getSubTaskObjects()
for (subTask in subTasksList) {
 // add a condition here if you DO NOT want to delete all the sub-tasks
 issueManager.deleteIssue(user, subTask, EventDispatchOption.ISSUE_DELETED, false)

But the last line issueManager.deleteIssue(user, subTask, EventDispatchOption.ISSUE_DELETED, false) is not working (I have tried to find an updated version of this for Jria 7.1 and above but can't find it anywhere).
