How to get list of Users an issue was assigned to.

[mickey13]

I am trying to get the list of Users that an issue was assigned to. Below, I think I am getting the string name for the user, but I was hoping to get the User object. The getField() method seems like the best candidate for what I'm trying to extract from the history, but I'm not sure how to get the User object. Any recommendations? Thanks.

def changeHistoryManager = ComponentManager.getComponentInstanceOfType(ChangeHistoryManager.class)
def issueAssigneeHistory = changeHistoryManager.getChangeItemsForField(issue, "assignee")
        
if (issueAssigneeHistory.size() >= 1) {
   assignee = issueAssigneeGroupHistory.last().getField()

Use UserManager. getUserByName or getUser depending on the JIRA version.

How can the assignee history be extracted by using UserManager? Thanks.

Thanks for your reply. Any ideas why userManager would be null?

UserManager userManager = ComponentManager.getComponentInstanceOfType(UserManager.class)

I've also tried:

UserManager userManager = ComponentAccessor.getUserManager()

But I get an error:

java.lang.IllegalStateException: ComponentAccessor has not been initialised.

Any ideas?

Can you try this?

def userManager = ComponentAccessor.getUserManager()

I still get the error:

java.lang.IllegalStateException: ComponentAccessor has not been initialised.

I ended up doing the following to get data associated with a username. Not sure why ComponentAccessor didn't work for me.

def componentManager = ComponentManager.instance
def test = componentManager.getUserUtil().getGroupNamesForUser(user.name)
