Bug#845113: scala: Upgrade to 2.12.x

[Antonio Ospite]

Package: scala
Version: 2.11.12-4
Followup-For: Bug #845113

Dear Maintainer,

I tried using the 'sbt' from debian to build scala 2.12.x and I get this
error:

-----------------------------------------------------------------------

the sbt-buildinfo plugin for sbt 0.13 is not available for scala 2.11:
https://dl.bintray.com/sbt/sbt-plugin-releases/com.eed3si9n/sbt-buildinfo/scala_2.11/

But only for scala 2.10:
https://dl.bintray.com/sbt/sbt-plugin-releases/com.eed3si9n/sbt-buildinfo/scala_2.10/

However this is only part of the problem, other dependencies too would
need to be updated in debian, like libjarjar-java which now have a new
upstream: https://github.com/pantsbuild/jarjar

I know this is not really helpful, I just wanted to give sbt a try and
see where we were at.

Ciao,
   Antonio
