如何在链接的Jira问题之间复制评论?

我需要让Jira将评论从父问题复制到链接的问题。为此,我正在尝试编写自定义侦听器。但我不知道如何找到这些相关的问题。我还将事件类型添加到“Issue Commented”。

我的听众:

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.event.issue.AbstractIssueEventListener;
import com.atlassian.jira.event.issue.IssueEvent;

import com.atlassian.jira.issue.link.IssueLinkType;
import com.atlassian.jira.bc.issue.link.IssueLinkService;

public class CopyComments extends AbstractIssueEventListener {

        @Override
        void workflowEvent(IssueEvent event) {

            def commentManager = ComponentAccessor.getCommentManager();
            def issueManager = ComponentAccessor.getIssueManager();
            def comment = event.getComment();

            ArrayList<String> linkedIssues = getLinkedEvents(event); 

            for (def i = 0; i < linkedIssues.size(); i++) {
                def targetIssue = issueManager.getIssueObject(linkedIssues[i]);
                commentManager.create(targetIssue, comment.authorApplicationUser, comment.body, true);

            }
        }

        ArrayList<String> getLinkedEvents(IssueEvent event) {

        }
    }

因此,问题是我如何在项目中找到这些相关问题?
