How to get Linked issues of an issue using API

[Srinivas Patruni]

I searched the issue object but i did not find any method which returns list of linked issues of an issue. How can we get that?

[RambanamP]

try with the following codefor Outward links

List<IssueLink> allOutIssueLink = ComponentAccessor.getIssueLinkManager().getOutwardLinks(sourceIssue.getId());
	for (Iterator<IssueLink> outIterator = allOutIssueLink.iterator(); outIterator.hasNext();) {
		IssueLink issueLink = (IssueLink) outIterator.next();
			if (issueLink.getIssueLinkType().getId() == linkId) {
				String key = issueLink.getDestinationObject().getKey();
			}
}

Same way you can do it for inward links

I get a null list when I try this, the Issue instance is not null and the issue has a link that I added my self.
I am triggering the method when the issue is modified.

Below is the Script to list Open Issues and Issue Links in a Project. You need to run it on the JIRA Script Console plugin.

import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.issue.MutableIssue;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.project.Project;
import com.atlassian.jira.issue.link.IssueLinkManager;
import com.atlassian.jira.issue.link.LinkCollectionImpl;
import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.issue.link.IssueLink;
import java.util.Collection;
import java.util.Iterator;
import org.apache.log4j.Logger;
import org.ofbiz.core.entity.GenericEntityException;
import java.util.HashSet;
import java.util.List;
import java.util.Set;
 
String projectKey = "RFD";
String transitionStatus = "Open";
IssueManager issueManager = ComponentAccessor.getIssueManager();
Long projectId = ComponentAccessor.getProjectManager().getProjectByCurrentKey(projectKey).getId();
Collection<Long> issueIdsForProject = issueManager.getIssueIdsForProject(projectId);
int issuesInTransition = 0;
String results = "<h3><b>Open Issues under Project: " + projectKey + "</b></h3></br>";
results = results + "<table border=1><tr><th>Issue</th><th>Links</th></tr>";
for (Long issueId : issueIdsForProject) {
   MutableIssue issue = issueManager.getIssueObject(issueId);
   if (issue.getStatusObject().getName().equals(transitionStatus)) {
      results = results + "<tr><td>" + issue.getKey() + " - " + issue.getSummary() + "</td><td>";    
      
      //Linked Issues
      List<IssueLink> allOutIssueLink = ComponentAccessor.getIssueLinkManager().getOutwardLinks(issue.getId());
       for (Iterator<IssueLink> outIterator = allOutIssueLink.iterator(); outIterator.hasNext();) {
         IssueLink issueLink = (IssueLink) outIterator.next();
         String key = issueLink.getDestinationObject().getKey();
         results = results + key + "(" + issueLink.getIssueLinkType().getName() + "), ";
      }
       
      results = results + "</td></tr>";    
      issuesInTransition++;
   }
}
results = results + "</table><br/><b> No. of Open Issues: " + issuesInTransition + "</b>";
return results;

Hope this helps!!

above code may help

Hi Srinivas,

You need to use the IssueLinkManager. See the API here

https://developer.atlassian.com/static/javadoc/jira/5.0.5/reference/com/atlassian/jira/issue/link/IssueLinkManager.html

Let me know if you need further help I can send you some sample code.

Cheers

Bhushan
