我正在尝试基于 Hortonworks 教程创建一个新的 Spark 应用程序。但是当我尝试导入必要的模块时，build.sbt 不断抛出以下错误。

我安装了 SCALA - 2.11.4 和 SBT 0.13。有什么帮助吗？？

构建.sbt

name := "sparkTutorialScala"

version := "1.0"

scalaVersion := "2.11.4"

libraryDependencies ++= {
  val sparkVer = "2.1.0"
  Seq(
    "org.apache.spark" %% "spark-core" % sparkVer % "provided" withSources()
  )
}

更新的错误消息：

好吧，SBT 1.0 与我使用的 IDEAJ 插件或 spark 版本不兼容。安装 SBT 0.13 而不是最新版本解决了这个问题。
