Meta build resolves to unused Scala 2.10.2

[eed3si9n]

steps

1. Use sbt 0.13.5 with the following plugins:

project/plugins.sbt:

addSbtPlugin("me.lessis" % "bintray-sbt" % "0.1.2")

addSbtPlugin("com.typesafe" % "sbt-mima-plugin" % "0.1.6")

ivyPaths :=  new IvyPaths((baseDirectory in ThisBuild).value, Some((baseDirectory in ThisBuild).value / "ivy-cache"))

build.sbt:

ivyPaths :=  new IvyPaths((baseDirectory in ThisBuild).value / "project", Some((baseDirectory in ThisBuild).value / "project" / "ivy-cache"))

Run:

$ sbt exit

problem

The meta build resolves to Scala 2.10.2 and downloads it.

expectation

The meta build uses Scala 2.10.4 (or which ever Scala version the sbt 0.13.x uses)

The workaround I posted in #1494:

libraryDependencies += "org.scala-lang" % "scala-compiler" % "2.10.4"

This seems to be working for me on sbt 0.13.5:

Before: sbt exit  18.17s user 1.61s system 13% cpu 2:31.44 total
After:  sbt exit  17.52s user 1.37s system 17% cpu 1:47.75 total

I might have been misled by the ongoing appearance of these artifacts, for which there are 2.10.4 versions. I realize that depending on the 2.10.4 library will not "back-propagate" the version to these, but in the haze of ivy output I must have seen the compiler jar everywhere.

I also might have scoped it to "scala-tool", foolishly it seems.
