Question

Answer 1

If in your Jenkins job you are using Groovy plug-in, then inside Execute system Groovy script step the plug-in already provides you access to some predefined variables:

build
    The current AbstractBuild.
launcher
    A Launcher.
listener
    A BuildListener.
out
    A PrintStream (listener.logger).

For example:

println build.getClass()

Outputs:

class hudson.model.FreeStyleBuild
