Trying to script adding watchers in JIRA 7.1.7, WatcherManager.startWatching() is complaining about types DelegatingApplicationUser and IssueImpl

DH_o6g85q

I'm trying to add watchers after a Story is added in a project. I've been bouncing all over existing questions and sample scripts, but changes in JIRA versions have rendered all the examples I could find as deficient in one way or another.

Not sure where this is breaking since from what I can tell DelegatingApplicationUser is an implementation of ApplicationUser and IssueImpl is an implementation of Issue.

groovy.lang.MissingMethodException: No signature of method: static com.atlassian.jira.issue.watchers.WatcherManager.startWatching() is applicable for argument types: (com.atlassian.jira.user.DelegatingApplicationUser, com.atlassian.jira.issue.IssueImpl) values: [johndoe(johndoe), ISS-01]

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.user.util.UserManager
import com.atlassian.jira.issue.watchers.WatcherManager


def userManager = ComponentAccessor.getUserManager()
def watchUsers = {usernames ->
  usernames.each {
    def user = userManager.getUserByName("${it}")
      WatcherManager.startWatching(user, issue)
  }
}

def users = ["johndoe","janedoe"]


if(issue.getIssueType().name=="Story"){
  watchUsers(users)
}

What the error says is that it cannot find such static method in WatcherManager - the key here being the word "static". The script is invoking startWatching() as a static method, it should be called on the instance instead:

def watcherManager = ComponentAccessor.getWatcherManager()
watcherManager.startWatching(user, issue)
