I've just downloaded Play Framework 2.1-RC1.
Within folders, I noticed that SBT folder includes itself Scala's compiler/library whose version is:
scala.2.10.0-RC1.
Previously, I used to compile some Scala programs with the more recent version:
scala.2.10.0-RC2
Should I stay with scala.2.10.0-RC1 provided by Play (in order to avoid potential incompatibility with Play)?
Further, is there a way (a specific Play's command-line?) to add automatically src-jars for Scala into Play's SBT folder (scala-library-src.jar etc...)? Indeed the folder structure contains currently only jars files:
Scala 2.10.0 final has been out for about a week, now. I'd expect that the Play artifacts are available for it by now and if they're not they surely will be soon.
