在使用Scala2.11添加GraphFrames构建时Build.sbt中断

Question

我正在尝试将GraphFrames添加到我的scala spark应用程序中，当我添加基于2.10的应用程序时，一切都很顺利。然而，当我尝试用GraphFrames build和Scala2.11构建它的时候，它就失败了。

问题是使用了冲突的scala版本(2.10和2.11)。我得到以下错误：

[error] Modules were resolved with conflicting cross-version suffixes in {file:/E:/Documents/School/LSDE/hadoopcryptoledger/examples/scala-spark-graphx-bitcointransaction/}root:
[error]    org.apache.spark:spark-launcher _2.10, _2.11
[error]    org.json4s:json4s-ast _2.10, _2.11
[error]    org.apache.spark:spark-network-shuffle _2.10, _2.11
[error]    com.twitter:chill _2.10, _2.11

[error]    com.fasterxml.jackson.module:jackson-module-scala _2.10, _2.11
[error]    org.json4s:json4s-core _2.10, _2.11
[error]    org.apache.spark:spark-unsafe _2.10, _2.11
[error]    org.apache.spark:spark-core _2.10, _2.11
[error]    org.apache.spark:spark-network-common _2.10, _2.11

然而，我不能诊断是什么导致了这种情况..这是我的完整build.sbt：

import sbt._
import Keys._
import scala._


lazy val root = (project in file("."))
.settings(
    name := "example-hcl-spark-scala-graphx-bitcointransaction",
    version := "0.1"
)
 .configs( IntegrationTest )
  .settings( Defaults.itSettings : _*)

scalacOptions += "-target:jvm-1.7"

crossScalaVersions := Seq("2.11.8")

resolvers += Resolver.mavenLocal

libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.1" % "test,it"

libraryDependencies += "graphframes" % "graphframes" % "0.5.0-spark2.1-s_2.11"

有人能指出哪个依赖项是基于scala 2.10导致构建失败的吗？

Answer 1

我发现了问题所在。显然，如果你使用：

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.0" % "provided"

默认使用2.10版本。当我将spark core和spark graphx的依赖项更改为：

libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "2.2.0"

libraryDependencies += "org.apache.spark" % "spark-graphx_2.11" % "2.2.0" % "provided"
