Accessing Variables Specified for Jenkins Groovy Plugin Script

Question

When writing a script that is run by Jenkins Groovy Plugin as a build step (Execute System Groovy Script) one can specify 'variable bindings'. The helpline says: Define varibale bingings (in the properties file format). Spefified variables can be addressed from the script. [sic] How do I access those variables from the script? They are not set as environment variables for the build, neither are they present among System properties.

this.getBinding().getVariables()

or simply binding.variables

Do you know how to access the environment variables in the script? – John Powel Nov 28 '12 at 16:07
@Newbie, `binding.varaibles` is a [java.util.Map](http://docs.oracle.com/javase/6/docs/api/java/util/Map.html) object (keyed by variable names). – malenkiy_scot Dec 23 '12 at 10:56

If you have a binding like `foo=bar` in your variable bindings, you can get `bar` by running `binding.variables.get('foo')`. – The Unknown Dev Feb 10 '16 at 17:14

I wasn't able to use binding.variables directly, I only got listener, build, launcher and out from binding.variables.

Instead I was able to use build.environment(listener) to retrieve the environment variables as suggested in the responses to this question: Access to build environment variables from a groovy script in a Jenkins build step ( Windows)

def config = new HashMap()
config.putAll(binding.variables)
def logger = config['out']
def envvars = new HashMap()
envvars.putAll(build.getEnvironment(listener))
def myvar= envvars['myvar']

This might have been different for me since I am only looking for system-wide environmental variables:
