Check Curent Version of Scala inside Dos Command Prompt

This one works for me:

sbt scalaVersion

Looks like you just need to go to the Windows shell, start SBT and check the Scala version there, e.g.

C:\> sbt

> scala-version

2.9.2 (or whatever)

Now, you have the SBT prompt and can type "console" to open the Scala REPL:

> console

scala> println("Hello")

Hello

You can quit the repl with :q and go back to the SBT prompt

scala> :q

>

Now you can quit SBT using Ctrl+C to go back to the Windows prompt:

C:\>
