Hi @Tarun Sapra,

Thank you for the code, this worked perfectly for adding users as default watchers. However I am struggling while trying to add group as default watcher. 

Could you please let me know if it is possible to add group as default watcher?

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.watchers.WatcherManager
import com.atlassian.jira.user.util.GroupManager
import com.atlassian.crowd.embedded.api.Group
import com.atlassian.jira.security.groups.GroupManager
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.bc.group.search.GroupPickerSearchServiceImpl
import java.lang.String

WatcherManager watcherManager = ComponentAccessor.getWatcherManager()
GroupManager groupManager = ComponentAccessor.getGroupManager()

def watchUsers = {groupnames ->;
groupnames.each {
watcherManager.startWatching(groupManager.getGroupByName((String)it), issue)
}
}

def grp = ["GrpTGJiraConfluenceSupport"]
watchUsers(grp)

Hello @Shivani Chauhan

Can you please create a separate question for this, as replying on an old thread which already has an solved question would create confusion for the users.

[Shivani Chauhan]

Hi @Tarun Sapra,

Thank you for the response. I have posted a new question. Could you kindly help us on that.

[Tarun Sapra]

As I have mentioned in my answer that componentManager is not used anymore and instead ComponentAccessor.

Instead of "componentManager.getUserUtil()" it should be

ComponentAccessor.getUserUtil()

@vasiliy  There is a typo in your answer.

Getting the below error after removing ComponentAccessor.getInstance()

[swetha meti]

Below is the complete script

package com.onresolve.jira.groovy.canned.workflow.postfunctions

import com.atlassian.jira.component.ComponentAccessor

def componentManager = ComponentAccessor.getInstance()

def watcherManager = ComponentAccessor.getWatcherManager()

def userManager = ComponentAccessor.getUserUtil()

def watchUsers = {usernames ->

   usernames.each {

         def user = userManager.getUser(it)

         watcherManager.startWatching(user, issue.getGenericValue())

      }

}

//Users can be added and removed from this list below. Make sure the names are in quotes and are comma separated.

   def users = ["lli", "skaravadi"]

   watchUsers(users)

getting the below error when i replaced import com.atlassian.jira.ComponentManager to import com.atlassian.jira.component.ComponentAccessor and ComponentManager.method to ComponentAccessor.method

remove the line - ComponentAccessor.getInstance() it's not required. As all the getter methods in the ComponentAccessor class are static thus call them directly like

ComponentAccessor.getWatcherManager()
ComponentAccessor.getUserManager()

etc

[Vasiliy Zverev]

Here is refactored version. Try this one. It is not clear for me where watchUsers variable is initialised, but it should work better:

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

WatcherManager watcherManager = ComponentAccessor.getWatcherManager()
UserManager userManager = componentManager.getUserUtil()

def watchUsers = {usernames ->
    usernames.each {      
        watcherManager.startWatching(userManager.getUserByName(it), issue)
    }
}

[Tarun Sapra]

"UserManager userManager = componentManager.getUserUtil()"

UserUtil can't be assigned to instance of UserManager and componentManger needs to be replaced by ComponentAccessor.

[Vasiliy Zverev]

Here is more one:

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

WatcherManager watcherManager = ComponentAccessor.getWatcherManager()
UserManager userManager = ComponentAccessor.getUserUtil()

def watchUsers = {usernames ->
    usernames.each {
        watcherManager.startWatching(userManager.getUserByName(it), issue)
    }
}

[Tarun Sapra]

This again won't work as this statement is wrong

UserManager userManager = ComponentAccessor.getUserUtil()

I have the provided the correct answer and has been accepted  "Complete code" please see that for correct code.

[Tarun Sapra]

The error is coming because your using the wrong class, instead of ComponentManager please use ComponentAccessor

https://developer.atlassian.com/static/javadoc/jira/latest/reference/com/atlassian/jira/ComponentManager.html - ComponentManager doesn't have the methods you need in latest JIRA API Docs 

While ComponentAccessor has all the methods which you are using like (getWatcherManager()) - https://developer.atlassian.com/static/javadoc/jira/latest/reference/com/atlassian/jira/component/ComponentAccessor.html
