Spark编译遇到ClassNotFoundException: xsbt.CompilerInterface的报错

用的是Scala。
附上build.sbt配置：

name := "SparkLibLinearDemo"

version := "1.0"

scalaVersion := "2.10.4"

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.2.0"

resolvers += "Akka Repository" at "http://repo.akka.io/releases/"

下面是打印的错误栈：

最后查到是依赖包的Scala版本和系统版本冲突导致的。
