Previous Epic Link

[Dan27]

Hello,

There is an option to get the previous 'Epic Link' of an issue? (by post function).

I need the Epic Link that was the parent of an issue (for example-story) before it was changed.

Maybe there is an option to get the 'Epic Link' history list of a specific issue ?

Thanks , Daniel

Hello @Dan27

You can get it via changeHistoryManager like this

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.MutableIssue

// Uncomment this to test is script console and place correct issue key
//MutableIssue issue = ComponentAccessor.getIssueManager().getIssueObject("TEST-1")

def changeHistoryManager = ComponentAccessor.getChangeHistoryManager()
def history = changeHistoryManager.getChangeItemsForField(issue, "Epic Link")
if (history.size()>1){
    def prevousEpicLink = history.last().fromString
    log.error("prevous epic: ${prevousEpicLink}")
}

Perfect Thanks ! :) @Mark Markov

No, How can I set this prevousEpicLink to the Epic Link field ?

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

// Uncomment this to test is script console and place correct issue key
//MutableIssue issue = ComponentAccessor.getIssueManager().getIssueObject("TEST-1")

def changeHistoryManager = ComponentAccessor.getChangeHistoryManager()
def history = changeHistoryManager.getChangeItemsForField(issue, "Epic Link")
def customField = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName("Epic Link")
def issueManager = ComponentAccessor.getIssueManager()
if (history.size()>1){
    def prevousEpicLink = history.last().fromString
    log.error("prevous epic: ${prevousEpicLink}")
    def epicIssue = issueManager.getIssueObject(prevousEpicLink)
    issue.setCustomFieldValue(customField, epicIssue)
    issueManager.updateIssue(null, issue, EventDispatchOption.DO_NOT_DISPATCH, false)
}
