I want to give user access for parameters in Jenkins basused on user role.

so I am using Role-based Authorization Strategy and Active Choices parameter plugins and trying to do this and I successfully gave user access for parameters based on user name but not based on user roles becouse I cant list users assiened roles with groovy

this example using user names but i need to know how to apply same concept with roles 

 

import jenkins.model.Jenkins

import hudson.model.User

// Get the current user

User currentUser = User.current()

// Get the username of the current user

String currentUsername = currentUser != null ? currentUser.fullName : null

// Define the available environments based on usernames

def envChoices = []

if (currentUsername == "DevUser1") {

envChoices += "DEV"

}

if (currentUsername == "QAUser1") {

envChoices += "QA"

}

// Check if the user has the role "admin" to list all parameters (DEV, QA, PROD)

{{if (currentUsername == "Admin")

{ envChoices += ["DEV", "QA", "PROD"] }

return envChoices}}
