我试图用sbt 0.13.8编译一个非常简单的火花项目，其唯一的功能是未解决的依赖问题，编译具有SBT
Test.scala
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
object SimpleApp {
def main(args: Array[String]) {
val logFile = "YOUR_SPARK_HOME/README.md" // Should be some file on your system
val conf = new SparkConf().setAppName("Simple Application")
val sc = new SparkContext(conf)
val logData = sc.textFile(logFile, 2).cache()
val numAs = logData.filter(line => line.contains("a")).count()
val numBs = logData.filter(line => line.contains("b")).count()
println("Lines with a: %s, Lines with b: %s".format(numAs, numBs))
}
}
的build.sbt火花项目时文件中的projet根目录如下：
name := "Test"
version := "1.0"
scalaVersion := "2.11.7"
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.2"
resolvers ++= Seq(
"Apache Repository" at "https://repository.apache.org/content/repositories/releases/",
"Cloudera Repository" at "https://repository.cloudera.com/artifactory/cloudera-repos/",
Resolver.sonatypeRepo("public")
)
错误返回sbt compile是：

我该如何解决这个依赖性问题？
编辑
我都跟着@ mark91的建议是：
- 变化斯卡拉版
2.10.5 - 变化火花依赖于
libraryDependencies += "org.apache.spark" % "spark-core_2.10" % "1.2.0-cdh5.3.2" % "provided"。
但是我仍然可以在org.scala浪＃斯卡拉库未解决的依赖; 2.10.4：
[error] sbt.ResolveException: unresolved dependency: org.scala-lang#scala-library;2.10.4: configuration not found in org.scala-lang#scala-library;2.10.4: 'master(compile)'. Missing configuration: 'compile'. It was required from org.apache.spark#spark-core_2.10;1.2.0-cdh5.3.2 compile
你有为什么我得到这个问题的任何想法？
当我使用Scala的2.10（准确地说2.10.4），我得到了一些错误。此外，还有两个未解决的依赖项：'org.scala-lang＃scala-library; 2.10.4'和'org.scala-lang＃scala-reflect; 2.10.4' – Pop
尝试使用2.10.5。我已经用我正在使用的一个工作示例更新了答案。 – mgaido
仍然存在您的新解决方案的问题：'[error] sbt.ResolveException：无法解析的依赖关系：org.scala-lang＃scala-library; 2.10.4：在org.scala-lang＃scala-library中找不到配置; 2.10.4：'master（compile）'。缺少配置：“编译”。它是从org.apache.spark需要＃spark-core_2.10; 1.2.0-cdh5.3.2编译 ' – Pop
