Access to build environment variables from a groovy script in a Jenkins build step (Windows)

Question

I'm using Scriptler plugin, so I can run a groovy script as a build step. My Jenkins slaves are running on windows in service mode. With scriptler, I don't need to use windows batch scripts.

But I have trouble to get the environment variables in a build step... This is working:

System.getenv("BASE") 

Where BASE is part of the env-vars on jenkins startup. However, I would like to get

%JOB_NAME% 

If I'm adding an "Execute Windows batch command" build step:

echo %JOB_NAME% 

It works. If I'm adding a scriptler script as a build step with the same settings:

println "JOB_NAME: " + System.getenv("JOB_NAME") 

I'm getting:

JOB_NAME: null 

So how can I reach the injected environment variables from a groovy script as a build step?

build and listener objects are presenting during system groovy execution. You can do this:

def myVar = build.getEnvironment(listener).get('myVar')
