Command line tools : option "-version"

[michelou]

Behavior of command line option -version is incorrect with Scala 3 (see also issue 11453) :

Scala 2 output

Behavior is consistent between scala, scalac and scaladoc :

$ export JAVA_HOME=/c/opt/jdk-1.8.0_282-b08/

user@host MINGW64 /w/dotty
$ /c/opt/scala-2.13.4/bin/scala -version

$ /c/opt/scala-2.13.4/bin/scaladoc -version
Scaladoc version 2.13.4 -- Copyright 2002-2020, LAMP/EPFL and Lightbend, Inc.

Scala 3 output

Only scalac behaves correctly :

user@host MINGW64 /w/dotty
$ /c/opt/scala-3.0.0-RC1/bin/scala -version

$ /c/opt/scala-3.0.0-RC1/bin/scaladoc -version

Failure

Expectation

Same behavior for Scala 2 and Scala 3.

@BarkingBad As of February 20 Scala 3 output looks as follows with PR #11476 :

With scaladoc the line Destination is not provided, ... still appears for me (local build based on PR #11476).

PS. No change with scala.
