[gradle] In Gradle, is there a better way to get Environment Variables?

In several Tasks, I reference jars in my home folder.

Is there a better way to get Environment Variables than

ENV = System.getenv()
HOME = ENV['HOME']

task copyToServer(dependsOn: 'jar', type: Copy) {

 from 'build/libs/'
 into HOME + "/something/plugins/"
}

This sets $HOME but I was hoping that I missed some magic from the documentation.

In android gradle 0.4.0 you can just do:

println System.env.HOME

classpath com.android.tools.build:gradle-experimental:0.4.0

I couldn't get the form suggested by @thoredge to work in Gradle 1.11, but this works for me:

home = System.getenv('HOME')

It helps to keep in mind that anything that works in pure Java will work in Gradle too.
