How to detect the current OS from Gradle

Question

I found this answer about how to do it with Groovy:

Detecting the platform (Window or Linux) by Groovy/Grails:

if (System.properties['os.name'].toLowerCase().contains('windows')) {
    println "it's Windows"
} else {
    println "it's not Windows"
}

Is there a better way?

Actually, I looked at the Gradle project, and this looks a little cleaner as it uses Ant's existing structure:

import org.apache.tools.ant.taskdefs.condition.Os

task checkWin() << {
    if (Os.isFamily(Os.FAMILY_WINDOWS)) {
        println "*** Windows "
    }
}

I found this in the following Gradle branch, and it seems to work nicely. gradle/gradle-core/branches/RB-0.3/build.gradle
