Update all issues with last assignee

[Chander Inguva]

Hi All,

• Is there any custom groovy script or function which will allow issues based on a JQL query to modify its assignee field value to its last assignee field value per issue ?
• Please share your thoughts on this.

Regards

Hi All,

         This is the tested and verified code for assigning previous value to assignee field based on a JQL Search.

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.issue.*;
import com.atlassian.jira.issue.history.ChangeItemBean;
import com.atlassian.jira.issue.changehistory.*;
import com.atlassian.jira.issue.changehistory.ChangeHistory;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.issue.MutableIssue;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.project.Project;
import com.atlassian.jira.project.ProjectManager;
import com.atlassian.jira.user.util.UserManager;
import com.atlassian.crowd.embedded.api.User;
import com.atlassian.jira.user.ApplicationUsers;
import com.atlassian.crowd.embedded.api.User;
import com.atlassian.jira.bc.issue.search.SearchService;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.user.util.UserUtil;
import com.atlassian.jira.web.bean.PagerFilter;
 
jqlSearch = "project = <Project_Name> AND issuetype = Story and status = Open and assignee is empty"
SearchService searchService = ComponentAccessor.getComponent(SearchService.class);
UserUtil userUtil = ComponentAccessor.getUserUtil();
User user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser();
//Managers
IssueManager issueManager = ComponentAccessor.getIssueManager();
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();
ChangeHistoryManager changeHistoryManager = ComponentAccessor.getChangeHistoryManager();
ProjectManager projectManager = ComponentAccessor.getProjectManager();
IssueFactory issueFactory = ComponentAccessor.getIssueFactory();
MutableIssue mIssue = issueFactory.getIssue();
List<Issue> issues = null;
SearchService.ParseResult parseResult =  searchService.parseQuery(user, jqlSearch)
if (parseResult.isValid()) 
{
    def searchResult = searchService.search(user, parseResult.getQuery(), PagerFilter.getUnlimitedFilter())
    issues = searchResult.issues.collect {issueManager.getIssueObject(it.id)}
    for (Issue issue  : issues)
	{
        List<ChangeItemBean> assigneeChHistory = changeHistoryManager.getChangeItemsForField(issue, "assignee");                             
        if (!assigneeChHistory.isEmpty()) 
		{
		    ChangeItemBean assigneeChItemBean = assigneeChHistory.get(assigneeChHistory.size() - 1);
     	    previousAssignee = assigneeChItemBean.getFrom();
            userManager = (UserManager)  ComponentAccessor.getUserManager()
     		User usera = userManager.getUser(previousAssignee);
            issue.setAssignee(usera);      
            issue.store();
		}
	}
}

Hope this helps.

Regards
