SBT crashes when it tries to fetch the version of scala. #1388

Closed nicolasstucki closed 6 years ago

nicolasstucki commented 8 years ago

I found this while executing tests using sbt-dotty.

The issue is that sbt tries to fetch the version from scala.tools.nsc.Properties throug reflection.

Code in sbt.ScalaInstance.slowActualVersion that call it is:

val v = try { Class.forName("scala.tools.nsc.Properties", true, scalaLoader).getMethod("versionString").invoke(null).toString }
catch { case cause: Exception => throw new InvalidScalaInstance("Scala instance doesn't exist or is invalid: " + label, cause) }

The stacktrace is:

sbt.InvalidScalaInstance: Scala instance doesn't exist or is invalid:

One hacky work around that I found is to add the following class in dotty

package sbt
object ScalaInstance {
  def slowActualVersion(): String = "2.11.8(dotty)"
}

This should be reproducible on https://github.com/nicolasstucki/dotty-project/tree/scalacheck using sbt test.

smarter commented 8 years ago

slowActualVersion is only called if fastActualVersion fails, this should not happen because the dotty jar should contain a compiler.properties file with the correct content ever since fc3221836bd28c98dbef64e564d6f4e8b6ae90db. Maybe when running the test the dotty jar is not present on the classpath?

Closing because this doesn't seem to be happening anymore.
