How to pass env variable to Gradle test via command line?

Question

I have a standard java project layout and in some of my tests i have System.getenv("my_var"). I'd like to do run my tests using command line (from CI server) and pass the value of env var. Something like

./gradlew test -Dmy_var=xyz

but of course, this one doesn't work as tests are run by different jvm. so what's the exact command to pass the env var? i would prefer not to change my build scripts, create new tasks etc. i just want to pass env var via commandline. how can i do it?
