Overview

This script creates a sub-task in Jira with the minimum fields required, then automatically links the sub-task to a specified parent issue.

Example

I want to split my team's workload into smaller chunks using sub-tasks; however, it is very time-consuming to do this manually. To save time, I can use this snippet to create sub-tasks of issues and automatically link these to the parent issue.

Good to Know

• If the specified reporter does not exist, the logger in user shall be assigned as reporter.
• If the specified priority does not exist, the default priority shall be assigned.

 

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.fields.config.manager.PrioritySchemeManager

// the issue key of the parent issue
final parentIssueKey = 'JRA-1'

// the issue type for the new issue - should be of type subtask
final issueTypeName = 'Sub-task'

// user with that user key will be the reporter of the issue
final reporterKey = 'auser'

// the summary of the new issue
final summary = 'Groovy Friday'

// the priority of the new issue
final priorityName = 'Major'

def issueService = ComponentAccessor.issueService
def constantsManager = ComponentAccessor.constantsManager

def subTaskIssueType = subtaskIssueTypes.findByName(issueTypeName)
assert subTaskIssueType : "Could not find subtask issue type with name $issueTypeName. Avaliable subtask issue types are ${subtaskIssueTypes*.name.join(", ")}"

// if we cannot find user with the specified key or this is null, then set as a  reporter the logged in user
def reporter = ComponentAccessor.userManager.getUserByKey(reporterKey) ?: loggedInUser

// if we cannot find the priority with the given name or if this is null, then set the default priority
def priorityId = constantsManager.priorities.findByName(priorityName)?.id ?: prioritySchemeManager.getDefaultOption(parentIssue)

def issueInputParameters = issueService.newIssueInputParameters().with {
    setProjectId(parentIssue.projectObject.id)
    setIssueTypeId(subTaskIssueType.id)
    setReporterId(reporter.username)
    setSummary(summary)
    setPriorityId(priorityId)
}

def validationResult = issueService.validateSubTaskCreate(loggedInUser, parentIssue.id, issueInputParameters)
assert validationResult.valid : validationResult.errorCollection

def issueResult = issueService.create(loggedInUser, validationResult)
assert issueResult.valid : issueResult.errorCollection
