Reading Custom Field value from linked Issue or EPIC through script runner

Question

Hi,

I would like to read custom field value from a linked EPIC. Once I am able to read the custom field value from EPIC/parent, I would like to set up this value to sub-task' custom field. I tried multiple forums but didn't help much.

I saw threads for reading custom field value, I am able to read custom field value from the issue I am in. However, a read from parent or epic is returning a null all times.

Thanks,

Smita

Your script would look like this

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.attachment.FileSystemAttachmentDirectoryAccessor
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.link.IssueLinkManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.link.IssueLink

def linkTypeList = ["Epic-Story Link"]

IssueLinkManager linkMgr = ComponentAccessor.getIssueLinkManager()
CustomFieldManager cfManager = ComponentAccessor.getCustomFieldManager();
def customField = cfManager.getCustomFieldObjectByName("custom field name")

for(IssueLink link in linkMgr.getInwardLinks(issue.id))
{
 if ( link.issueLinkType.name in linkTypeList) {
   log.error(link.getSourceObject().getCustomFieldValue(customField))
 }
}

Hi Alex, I have this code which is reading value from linked EPIC and custom field value from its own custom field. However I am very new to scripting and I am not sure how can I make it read custom field value from a linked issue or EPIC. I tried few scripts and removed them when they didn't work. import com.atlassian.jira.component.ComponentAccessor import com.atlassian.jira.issue.attachment.FileSystemAttachmentDirectoryAccessor import com.atlassian.jira.component.ComponentAccessor import com.atlassian.jira.issue.link.IssueLinkManager import com.atlassian.jira.issue.CustomFieldManager String testlinkType = ["IT Parent"] String testlinkStatus = ["child of"] def output ="" IssueLinkManager linkMgr = ComponentAccessor.getIssueLinkManager() CustomFieldManager cfManager = ComponentAccessor.getCustomFieldManager(); output+="issue key: " + issue.key +"

" for(IssueLink link in linkMgr.getInwardLinks(issue.id)) { output+="linked issue type: " + link.issueLinkType.name+"

"     output+="linked issue key: " + link.getSourceObject().getKey()+"

"    output+="linked issue status (name): " + link.getSourceObject().getStatus().getName()+"

"     output+="linked issue status (id): " + link.getSourceObject().getStatus().getId()+"

"    // output+=link    CustomField customField = cfManager.getCustomFieldObjectByName("Work Category");    def customFieldValue = customField.getValue(issue)    output+="My work category" + customFieldValue +"

"     //def customField = cfManager.getCustomFieldObject("Work Category")     //   def childCfValue =link.getCustomFieldValue(customField) }
