it:testOnly does nothing. Why?

Hi!

I have some simulation in src/it/scala/pac/Test.scala. If I run SBT task it:test, it does work. If I run it:testOnly args, where arg is anything (say, pac.Test), it says “No test to run”.
But it:test does run the only simulation in it/.

What have I missed?

Scala 2.11.8, SBT 0.13.11 and Gatling 2.1.7 are in use.

Well, gatiling-it:testOnly fqn does work. So, it just “short form” doesn’t work only.
