Answer 1

To retrieve all env properties using a Jenkinsfile written in either declarative or scripted DSL you can use:

sh 'env'                       

or

sh 'printenv'

As said over here: https://stackoverflow.com/a/42138466/618253

The declarative pipeline way of doing things:

node {
   echo sh(returnStdout: true, script: 'env')
}

Answer 3

Make sure you're not running the pipeline script in sandboxed mode and you should be able to use:

env.getEnvironment()

Note, if you're running in sandbox mode in a pipeline, you should approve the method at the script approval page: http://jenkins-host/scriptApproval/
