When I update the sub task's due date longer than the parents due date, is it possible to make the parents' due date same with the sub-task which is the longest in sub-tasks.

[Sangjun Jeon]

When I update sub task's due date longer than the parents due date,

is it possible to automatically make the parents' due date same with the sub-task which is the longest in sub-tasks?

[Vasiliy Zverev]

So, here is a script which 

• find parent issue for a subtask
• find max dueDate of all subtasks
• set this date to parent issue

It means that this script has to be postfunction on transition to change subtask due date. Since you have to add this postfunction to every transition. It is better to have the only transition to change due date. 

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue

import java.sql.Timestamp

/**
 * Set max DueDate of all subtasks to parent issue
 */

Issue issue = null;
//Get parent issue
MutableIssue parentIssue = issue.getParentObject();

//Get max due date of all subtasks
Timestamp maxSubtakDueDate = issue.getDueDate();
for(Issue subtask : parentIssue.getSubTaskObjects())
    if( (subtask.getDueDate() != null) && (subtask.getDueDate().after(maxSubtakDueDate)))
        maxSubtakDueDate = subtask.getDueDate();

//Update parent if requred
if(parentIssue.getDueDate().equals(maxSubtakDueDate)){
    parentIssue.setDueDate(maxSubtakDueDate);
    ComponentAccessor.getIssueManager().updateIssue(ComponentAccessor.getJiraAuthenticationContext().getUser().getDirectoryUser(), parentIssue,EventDispatchOption.ISSUE_UPDATED, false)
}

P.S.

It is possible to use sime event listener and execute this script on any issue update event, but I do not do it before.

[Sangjun Jeon]

Thanks a million! I will try with that code. I don't forget your name. I remember it. I owe you a lot.

For "if( (subtask.getDueDate() != null) && (subtask.getDueDate().after(maxSubtakDueDate)))" I get a static type checking error. "reference to method is ambiguous." Ideas?

[Vasiliy Zverev]

Try this one

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue

import java.sql.Timestamp

/**
 * Set max DueDate of all subtasks to parent issue
 */

//Comment it into postfunction
Issue issue = ComponentAccessor.getIssueManager().getIssueObject("");
//Get parent issue
MutableIssue parentIssue = issue.getParentObject();

//Get max due date of all subtasks
Timestamp maxSubtakDueDate = parentIssue.getDueDate();
for(Issue subtask : parentIssue.getSubTaskObjects())
    if( (subtask.getDueDate() != null) && (subtask.getDueDate().after(maxSubtakDueDate)))
        maxSubtakDueDate = subtask.getDueDate();

//Update parent if requred
if(parentIssue.getDueDate().equals(maxSubtakDueDate)){
    parentIssue.setDueDate(maxSubtakDueDate);
    ComponentAccessor.getIssueManager().updateIssue(ComponentAccessor.getJiraAuthenticationContext().getUser().getDirectoryUser(), parentIssue,EventDispatchOption.ISSUE_UPDATED, false)
}

[James Fishwick]

MutableIssue parentIssue = issue.getParentObject();

Cannot assign value of com.atlassian.jira.issue.Issue to variable of type com.atlassian.jira.issue.MutableIssue

( subtask.getDueDate() != null )

Reference to method is ambigious. Cannot choose between boolean java.sql.Timestamp#equals(java.lang.Object) , java.sql.Timestamp#equals(java.sql.Timestamp)

[James Fishwick]

Also, how do I target just due date changes in a postfunction?

[Vasiliy Zverev]

For postfunction it is possible to use more simple code:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue

import java.sql.Timestamp

/**
 * Set max DueDate of all subtasks to parent issue
 */

//Comment it into postfunction
//Issue issue = ComponentAccessor.getIssueManager().getIssueObject("");
//Get parent issue
MutableIssue parentIssue = issue.getParentObject();

//Get max due date of all subtasks
for(Issue subtask : parentIssue.getSubTaskObjects())
    if( (subtask.getDueDate() != null) && (subtask.getDueDate().after(parentIssue.getDueDate())))
        parentIssue.setDueDate(subtask.getDueDate());

i'm trying to make something like this, but in my case I need a script just to change the subtask due date when I change my parent issue due date, I need the same date...How can I do?

[Deepak Maharana]

For some reason "parentIssue.setDueDate(subtask.getDueDate())" does not work. Referred the solution given in https://community.atlassian.com/t5/Answers-Developer-Questions/Update-subtask-due-date-when-parent-issue-due-date-updated/qaq-p/481579. The below code checks the subtask with most future date and updates the parent issue.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.MutableIssue
import java.sql.Timestamp
import org.apache.log4j.Logger
import org.apache.log4j.Level

def log = Logger.getLogger("")
log.setLevel(Level.DEBUG)
/** 
  * Set max DueDate of all subtasks to parent issue 
*/
//Get parent 
MutableIssue issue = issue;
MutableIssue parentIssue = issue.getParentObject();

MutableIssue subtaskWithMaxDueDate = returnMostFutureDate(parentIssue, issue);

//Get max due date of all subtasks and set the parent's due date
if( (subtaskWithMaxDueDate.getDueDate() != null) && !(subtaskWithMaxDueDate.getDueDate().equals(parentIssue.getDueDate()))) {    
     def dateToSet = subtaskWithMaxDueDate.dueDate.format("d/MMM/yy");
     updateDueDate(parentIssue, dateToSet);
     log.info("Updated parent issue ${parentIssue} due date");
}

def returnMostFutureDate(def parentIssue, def currentIssue) {
    issueWithLatestDate = currentIssue;
    for(Issue subtask : parentIssue.getSubTaskObjects()) {        
       if( (subtask.getDueDate() != null) && (subtask.getDueDate().after(issueWithLatestDate.getDueDate()))) {            
            issueWithLatestDate = subtask;
       }
    } 
    return issueWithLatestDate;
}

def updateDueDate (def issue, def dueDateParam) { 
    def issueService = ComponentAccessor.getIssueService() 
    def issueInputParameters = issueService.newIssueInputParameters() 
    def user = ComponentAccessor.getJiraAuthenticationContext().loggedInUser  
    issueInputParameters.with { dueDate = dueDateParam } 
    
    def validationResult = issueService.validateUpdate(user, issue.id, issueInputParameters) 

    assert !validationResult.errorCollection.hasAnyErrors() 
    issueService.update(user, validationResult) 
    log.debug "Subtask ${issue.key} updated"
}

Jeon, do not give up so fast. 

I can help you to write a script (it is simple). But to run it you need a ScriptRunner. Is it possible to use ScriptRunner plugin for you (free for JIRA 6)?

[Sangjun Jeon]

Yes. Possible! Thank you so much for your help in advance.

[Sangjun Jeon]

Thanks.But I am not professional to make a script code. I'd like to know the Jira base function. Hm... Anyway thank for your help.

[Phill Fox]

To achieve this you will need to add a script plugin such as ScriptRunner which can take your change and review the parent task due date for differences.

[Sangjun Jeon]

Thanks.But I am not professional to make a script code. I'd like to know the Jira base function. Hm... Anyway thank for your help.

[Nic Brough -Adaptavist-]

There is no "base function", you need to find/write code to do it. ScriptRunner makes it easy, but it's still coding.

[Vasiliy Zverev]

You need some script for it. Is it acceptable solution for you?
