scala - Sbt:为什么它需要 Scala-lang 2.10.3？

Question

我的 build.sbt:

import android.Keys._

android.Plugin.androidBuild

name := "teacher-journal"

scalaVersion := "2.11.0"

proguardCache in Android ++= Seq(
    ProguardCache("org.scaloid") % "org.scaloid"
)

proguardOptions in Android ++= Seq("-dontobfuscate", "-dontoptimize", "-dontwarn scala.collection.mutable.**")

libraryDependencies += "org.scaloid" %% "scaloid" % "3.3-8"

scalacOptions in Compile += "-feature"

run <<= run in Android

install <<= install in Android

它给了我一个错误:

[warn]  ::::::::::::::::::::::::::::::::::::::::::::::
[warn]  ::          UNRESOLVED DEPENDENCIES         ::

Sbt 0.13.2, system scala 2.10.2, java 8, fedora 20. 为什么需要scala 2.10.3以及如何修复错误？

我的 friend 在 Ubuntu 上配置类似，一切都正常。
