This is the same as GRADLE-1553.

You’re missing the leading “:” prefix on the task path. So you need to invoke with as…

```gradle
gradle -D:subproject:seleniumTest.single=MyTest

```

I’ll update the instructions on the ticket.

We’re aware that this is a little cumbersome, and will be improved in the future.
