build.sbt 添加 spark-mllib 时中断

Question

我的 build.sbt 文件中有以下内容：

import AssemblyKeys._

assemblySettings

name := "acme-get-flight-delays"
version := "0.0.1"
scalaVersion := "2.10.5"

libraryDependencies ++= Seq(
  "org.apache.spark" %% "spark-hive" % "1.6.0",
  "org.scalanlp" %% "breeze" % "0.11.2",
  "net.liftweb" %% "lift-json" % "2.5+",
  "com.github.seratch" %% "awscala" % "0.3.+"
)

它与 sbt assembly 构建得很好。

但是，如果我尝试添加

  "org.apache.spark" % "spark-mllib_2.11" % "1.6.2"

作为依赖项，我收到以下错误：

我做错了什么？

看来是版本兼容性问题，请在下方尝试。

"org.apache.spark" % "spark-mllib_2.10" % "1.6.2"
