fsc error when running scala script

[Noel Yap]

This works when using Scala 2.10 and is broken in both 2.11 and 2.12.

The following script:

#!/bin/bash

exec /opt/scala-2.12/bin/scala "$0"

!#

println("aoeu")

errors with:

fscbad option: '-Xsource:2.12.0'

  fsc -help  gives more information

error: source file '/home/nyap/proj/sum-of-power/-Xsource:2.12.0' could not be found

one error found

You have to kill the compile server before running a different version.

$ scala210 y.scala
hi
$ scala y.scala

fscbad option: '-Xsource:2.12.0'
  fsc -help  gives more information

error: source file '/home/apm/tmp/-Xsource:2.12.0' could not be found
one error found
$ ~/scala-2.10.6/bin/fsc -shutdown

$ scala y.scala
hi
$ ~/scala-2.12.1/bin/fsc -shutdown

I use -nocompdaemon in all my Scala scripts now, after having been bitten by this far more times than I care to admit.
