JQL search with a different user when scripting: Scriptrunner

[Andrew Lonardelli]

I am trying to change the user when doing a JQL search for a scripted field. I realizd that the current user will not be able to browse the project so I would need to use a user that is able to browse the project. A piece of my script can be seen below.  I would like to change the def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser() to a different user. As an example, maybe the user name can be JohnDoe

maybe

def user = ComponentAccessor.getJiraAuthenicationContext().getUserByName("JohnDoe")

import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.crowd.embedded.api.User;
import com.atlassian.jira.user.ApplicationUser;
import com.atlassian.jira.bc.issue.search.SearchService;
import com.atlassian.jira.web.bean.PagerFilter;
import java.lang.Object
import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.fields.CustomField
import static java.lang.Math.*
import org.apache.log4j.Logger
import org.apache.log4j.Level

def log = Logger.getLogger("com.acme.CreateSubtask")
log.setLevel(Level.DEBUG)


boolean check =true


String jqlVaca = 'project = HR AND issuetype = "Employee Information"';
log.debug("Get filter string")

// Get a search-Object for JIRA
SearchService searchService = ComponentAccessor.getComponent(SearchService.class)

def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
def issuesInfo
SearchService.ParseResult parseResultVaca =  searchService.parseQuery(user, jqlVaca)


if (parseResultVaca.isValid()) {
   	 issuesInfo = (searchService.search(user, parseResultVaca.getQuery(), PagerFilter.getUnlimitedFilter()).getIssues())
log.debug("Parse is Valid")
} 
else
	check =1;

JiraAuthenticationContext

It has the function "setLoggedInUser(ApplicationUser user)". 
This is used in places like Jelly where we need to switch the identity of a user during execution.

To get the user i think you need UserManager and the getUserByName (or Key) function.

 I never used it but this should be the function you need.
