Jenkins File - Execute shell command in active choice script - jenkins

Question

everyone, I'm using plugin "Active Choices" in my Jenkins, I try to do something condition, and the return based on environment host that will be executed in shell command in my Jenkins file. the command like "echo ${BUILD_ENVIRONMENT}, echo ${BUILD_VERSION}..etc".
Already doing this but the list is still empty. now, what do I have to do to make this work? thank you.
JenkinsFile:
properties([
parameters([
[$class: 'ChoiceParameter',
choiceType: 'PT_SINGLE_SELECT',
name: 'ENVIRONMENT',
description: 'Select Environment',
script: [
$class: 'GroovyScript',
script: [
classpath: [],
sandbox: true,
script: '''
def getEnvVar(String name) {
return sh(script: "echo \${$name}", returnStdout: true).trim()
}
def env = getEnvVar("ENVIRONMENT")
if (envs != "testing") {
return ["stage", "dev", "prod"]
}else{
return ["testing"]
}
''',
],
]
]
])
])
Output:

im fix it with another solution, but maybe isnt the best option.
1st create a method to load the env file (i set the values on it), then define to jenkins global variable.
getEnvHosts = { ->
node {
script {
// Get the environment hosts file
def props = readProperties file: '/var/lib/jenkins/env/dast-service-env'
//define to jenkins global variable
env.BUILD_ENVIRONMENT = props['BUILD_ENVIRONMENT']
}
}
}
and then i call the "BUILD_ENVIRONMENT" with ${env.BUILD_ENVIRONMENT} like this in active choice parameter:
getEnvHosts()
properties([
parameters([
[$class : 'ChoiceParameter',
choiceType : 'PT_SINGLE_SELECT',
name : 'BUILD_ENVIRONMENT',
description: "Select Environment default is ${env.BUILD_ENVIRONMENT}",
script : [
$class: 'GroovyScript',
script: [
classpath: [],
sandbox : true,
script : """
def envs = "${env.BUILD_ENVIRONMENT}"
if (envs == "stage") {
choices = ["stage", "dev", "prod", "testing"]
}else if (envs == "dev") {
choices = ["dev", "prod", "stage", "testing"]
}else if (envs == "prod") {
choices = ["prod", "dev", "stage", "testing"]
}else{
choices = ["testing", "stage", "dev", "prod"]
}
return choices
""",
],
]
],
])
])
