retrive command line -D option in Java maven project

Question

Maven CLI Options Reference says -D option define a system property. The question is how to retrieve this option in Java Code.

I tried the following snippet and command, but couldn't retrieve it.

public class Test2Class {

    @Test
    public void test() {
        System.out.println((new Properties()).get("env"));
    }
}

mvn -Dtest=Test2Class test -Denv=dev

What else should I do to make it work?

Properties p = System.getProperties();
p.get("my.property");

or

System.getProperty("my.property")
