Get Issues In Epic in Scripted Field

[Paul Tiseo]

Using ScriptRunner for JIRA (Server), I want to create a custom field (HTML) that shows the ID and Summary fields of the child issues in the epic. How would I get that list of data using JIRA's API?

Ended up solving it myself:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.link.IssueLinkManager
import com.atlassian.jira.issue.link.IssueLinkTypeManager

IssueLinkTypeManager issueLinkTypeManager = ComponentAccessor.getComponent(IssueLinkTypeManager)
IssueLinkManager issueLinkManager = ComponentAccessor.issueLinkManager

def sb = new StringBuilder()

def linkType = issueLinkTypeManager.getIssueLinkTypes(false).find{ it.name == 'Epic-Story Link' }
def issueLinkList = issueLinkManager.getOutwardLinks(issue.id).findAll{ it.getLinkTypeId() == linkType.getId() }
for (issueLink in issueLinkList) {
 def childIssue = issueLink.getDestinationObject()
 sb <<= '<a href=\'https://projects.jtafla.com/browse/'
 sb <<= childIssue.getKey()
 sb <<= '\'>'
 sb <<= childIssue.getKey()
 sb <<= '</a> ('
 sb <<= childIssue.getSummary()
 sb <<= '), '
}
return sb
