How to set environment variables in a Jenkins Scripted Pipeline?

According to the Jenkins docs, this is how one sets a Global Environment Variable for a Declarative Pipeline:

pipeline {
    agent {
        label 'my-label'
    }
    environment {
        value = 'World'
    }
    stages {
        stage("Test") {
            steps {
                sh 'echo Hello, ${value}'
            }
        }
    }
}

The output is "Hello, World" as expected.

What is the correct way to do this in a Scripted Pipeline? The following does not error, but it does not work:

node('my-label') {
    environment {
        value = 'World'
    }
    stage("Test") {
        sh 'echo Hello, ${value}'
    }
}

The output is "Hello, ". That is not as expected.

In Scripted Pipelines (and in script sections of Declarative Pipelines) you can set environment variables directly via the "env" global object.

node {
    env.MY_VAR = 'my-value1'
}

You can also set variables dynamically like this:

node {
    def envVarName = 'MY_VAR' 
    env.setProperty(envVarName, 'my-value2')
}

Click Toggle Scripted Pipeline at this link

Jenkinsfile (Scripted Pipeline)

  node {
      withEnv(['DISABLE_AUTH=true',
               'DB_ENGINE=sqlite']) {
          stage('Build') {
              sh 'printenv'
          }
      }
  }

Your script should look something like the following:

  node('my-label') {
      withEnv(['value=World']) {
           stage('Test') {
               sh 'echo Hello, ${value}'
           }
      }
  }
