How to Add a Watcher Based on the Value of a System Field

[Jose Sepulveda]

I'm trying to add 1 user as a watcher on a post function once a ticket is created. I'm using script runner and this is the syntax I currently have:

import com.atlassian.jira.component.ComponentAccessor 
def userManager = ComponentAccessor.getUserManager() 
def watcherManager = ComponentAccessor.getWatcherManager() 
def user = userManager.getUserByName("jhobson1") 

if (issue.Components.equals("DART")){ 
watcherManager.startWatching(user, issue) }

 Essentially if the components system field equals "DART" the user should be added as a watcher. Unfortunately, it doesn't do anything.

Thanks for any help.

It’s better to do this not in the post-function when creating, but as a listener, listening to the issue creation event.
Why: Because scripts tend to grow, new ones are added, as a result, issues begin to take a longer time to create, the entire service begins to slow down.

I wrote it for MyGroovy, but I think the principle is the same for Scriptrunner.

import com.atlassian.jira.component.ComponentAccessor

//issue = getIssue('TASK-1')
issue = event.issue
def component_id = 11111 //test component



if (issue.components.find{it.id == component_id}){
startWatching(getUserByName('username'), issue)
}

def getUserByName(String userName){
ComponentAccessor.userManager.getUserByName(userName)
}

def startWatching(user, issue){
ComponentAccessor.watcherManager.startWatching(user, issue)
}
