为什么斯派克在智能J的sbt上出问题？

Question

name := "name"

version := "1.0"

scalaVersion := "2.11.7"

libraryDependencies += "org.apache.spark" %% "spark-core" % "2.0.2"

日志：

[warn] Multiple dependencies with the same organization/name but different versions.
To avoid conflict, pick one version:
[warn]  * org.scala-lang:scala-compiler:(2.11.0, 2.11.7)
[warn]  * org.scala-lang:scala-library:(2.11.8, 2.11.7)
[warn]  * org.scala-lang.modules:scala-parser-combinators_2.11:(1.0.1, 1.0.4)
[warn]  * org.scala-lang.modules:scala-xml_2.11:(1.0.2, 1.0.4)

Answer 1

通过检查依赖树，可以排除不需要的依赖项版本。

or

以专门的方式告诉sbt选择一个您想要的：

libraryDependencies ++= Seq(   
   "org.scala-lang" % "scala-compiler" % "2.11.7",   
   "org.scala-lang.modules" % "scala-parser-combinators_2.11" % "1.0.4",
   "org.scala-lang" % "scala-library" % "2.11.7",   
   "org.scala-lang.modules" % "scala-xml_2.11" % "1.0.4" 
)
