How add watchers in scriptrunner?

[Alex]

Hello everyone! I have a code which add watchers in issue. 
but now I need to add a user only if the task : task type is "my task type" and it has a field "my cf select list" and the option "Yes" is selected there. Please tell me how can I do this? Thank you.

import com.atlassian.jira.component.ComponentAccessor

def userManager = ComponentAccessor.getUserManager()
def watcherManager = ComponentAccessor.getWatcherManager()

def watcher = ["username1","username2"]

watcher.each{userName->
def user=ComponentAccessor.userManager.getUserByName(userName)
watcherManager.startWatching(user, issue)
}

The issue is created of the specific type and has the specific value for the customfield, correct (the field is of what type (text, number, list single or multiple choice, etc.))?

I can give you old examples that I already have, and they can be rewritten using HAPI.
How to set a single user as a watcher:

import com.atlassian.jira.component.ComponentAccessor

def userName = 'user_name' // Name of the user

def userManager = ComponentAccessor.getUserManager()
def user = userManager.getUserByName(userName)

if (!user) {
log.warn("User ${userName} not found")
return
}

def watcherManager = ComponentAccessor.getWatcherManager()

// Apply when the issue is of "Change Request" type
if (issue.getIssueTypeId() == '42') {
watcherManager.startWatching(user, issue)
}

How to set two users as watchers:

import com.atlassian.jira.component.ComponentAccessor

def firstUserName = 'user_name' // Name of the user
def secondUserName = 'user_name' // Name of the user

def userManager = ComponentAccessor.getUserManager()
def firstUser = userManager.getUserByName(firstUserName)
def secondUser = userManager.getUserByName(secondUserName)

if (!firstUser) {
log.warn("User with name ${firstUserName} not found")
}

if (!secondUser) {
log.warn("User with name ${secondUserName} not found")
}

def watcherManager = ComponentAccessor.getWatcherManager()

// Apply when the issue is of "Bug" type
if (issue.getIssueTypeId() == '1') {
watcherManager.startWatching(firstUser, issue)
watcherManager.startWatching(secondUser, issue)
}

How to set all the people from DL into watchers (leave only one FOR loop):

import com.atlassian.jira.component.ComponentAccessor

def DL = 'WFT Business Desk Atlassian Support' // Replace the name to your DL

def groupManager = ComponentAccessor.getGroupManager()
def watcherManager = ComponentAccessor.getWatcherManager()

def membersOfDL = groupManager.getUsersInGroup(DL, false) // without inactive users

if (membersOfDL) {
// Use only one method and delete the others
// Using enhanced for-loop
for (user in membersOfDL) {
watcherManager.startWatching(user, issue)
}
// Using FOR
for (int i = 0; i < membersOfDL.size(); i++) {
watcherManager.startWatching(membersOfDL[i], issue)
}
// Using EACH
membersOfDL.each {
watcherManager.startWatching(it, issue)
}
// Using FOREACH
for (member in membersOfDL) {
watcherManager.startWatching(member, issue)
}
}

I came up with the following solution that meets my needs:

import com.atlassian.jira.component.ComponentAccessor

// get instances of the user and watcher managers
def userManager = ComponentAccessor.getUserManager()
def watcherManager = ComponentAccessor.getWatcherManager()

// define the list of users to be added as watchers
def watcher = ['user1','user2','user3','user4']

// add each user from the list as a watcher to the current issue
watcher.each{userName->
    def user=ComponentAccessor.userManager.getUserByName(userName)
    watcherManager.startWatching(user, issue)
}
