sbt.librarymanagement.ResolveException：未解析的依赖项：org.scala-lang #scala-library; 2.2.0：未找到

Question

我正在使用依赖：

version := "0.1"

scalaVersion := "2.2.0"

libraryDependencies += "org.apache.spark" %% "spark-core" % "2.2.0"

导入依赖项时我收到错误

  

[error] sbt.librarymanagement.ResolveException：未解析的依赖项：   org.scala-lang #scala-library; 2.2.0：not found *

Answer 1

没有scalaVersion 2.2.0使用scalaVersion := "2.11.8"

我猜您将sparkVersion称为2.2.0

scalaVersion := "2.11.8"
val sparkVersion := "2.2.0"

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