inheriting epic name to subtask

[NathanG]

This isn't really a question, more of something we did at our company to be able to tie Epics, stories, and subtasks to the epic.

We did this by using script runner and creating a scripted field, and then for the scripted field we used this code:

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.Issue;
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();
CustomField epicLink = customFieldManager.getCustomFieldObjectByName('Epic Link');
CustomField epicName = customFieldManager.getCustomFieldObjectByName('Epic Name');
//This is where we store the issue that is linked to the epic.
Issue issue_linked_to_epic
/* determine if this is an epic, if so, return the epic link name */
if (issue.issueTypeObject.name == "Epic"){
	return issue.getCustomFieldValue(epicName)
}
/*determine if this is a subTaskIssueTypes(), if so, set the parent to the issue linked to the epic */
Issue issueParent = issue.getParentObject()
if (issueParent == null){
	issue_linked_to_epic = issue
} else {
	issue_linked_to_epic = issueParent
}
/* get epic link */
Issue epic = issue_linked_to_epic.getCustomFieldValue(epicLink)
if (epic == null){
	return null
}
String epicNameString = epic.getCustomFieldValue(epicName)
return epicNameString

Now we have a single custom field, "Epic Name for Reporting" that we can use in Filters to tie subtasks, stories, and epics together.

Thank You!

It's really usefull script.

I builded my own, based on your idea, to extract Epic ID from Epic Link 

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.Issue;

if (issue.issueTypeObject.name == "Story")
{
    CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();
 CustomField epicLink = customFieldManager.getCustomFieldObjectByName('Epic Link');
 Issue epic = issue.getCustomFieldValue(epicLink)
 if (epic == null)
    {
    return null
 }
 String nazwaID = epic.getKey()
 return nazwaID
}
return null

Hey J,

If you cast the Object to an Issue, it will work.

Try this: Issue epic = (Issue) issue_linked_to_epic.getCustomFieldValue(epicLink)

Hi it seems it doesn´t work with the server version, for e. g. the issue object is always empty if it´s an epic?

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.Issue;
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();
CustomField epicLink = customFieldManager.getCustomFieldObjectByName('Epic Link');
CustomField epicName = customFieldManager.getCustomFieldObjectByName('Epic Name');
//This is where we store the issue that is linked to the epic.
Issue issue_linked_to_epic
/* determine if this is an epic, if so, return the epic link name */
if (issue.issueTypeObject.name == "Epic"){
return issue.getCustomFieldValue(epicName)
}
/*determine if this is a subTaskIssueTypes(), if so, set the parent to the issue linked to the epic */
Issue issueParent = issue.getParentObject()
if (issueParent == null){
issue_linked_to_epic = issue
} else {
issue_linked_to_epic = issueParent
}
/* get epic link */
Issue epic = (Issue) issue_linked_to_epic.getCustomFieldValue(epicLink)
if (epic == null){
return null
}
String epicNameString = epic.getCustomFieldValue(epicName)
return epicNameString

Hello ,

I have run the script, it gives me the following error:
Error
null
java.lang.NullPointerException.

Please, can someone tell me how to fix it ...
I have Jira server 8.8

Thanks in advance

I hadn't had time to get back to this since this original posting but your fix did the trick! 

Many thanks!

[Jon Starbird]

Nathan, in 7.1 your script gives a couple of errors. One of them I was able to fix but the second one I'm not sure about. 

The second one is this line: Issue epic = issue_linked_to_epic.getCustomFieldValue(epicLink)

and scriptrunner now says Cannot assign value of type java.lang.object to variable of type com.atlassian.jira.issue.Issue

Anyway I'm just not sure what to change this to, have you updated to 7.1 yet and if so what was the change that was needed?
