冲突的跨版本后缀

Question

以下是我最近添加到我的项目中的build.sbt文件的一部分，用于为应用程序构建应用程序接口。

libraryDependencies ++= Seq(
  "com.chuusai" %% "shapeless" % "2.3.1"
)

libraryDependencies ++= {
  val sprayVersion = "1.3.1"
  val akkaVersion = "2.3.4"
  Seq(
    "io.spray" % "spray-can" % sprayVersion,
    "io.spray" % "spray-routing" % sprayVersion,
    "io.spray" % "spray-testkit" % sprayVersion,
    "io.spray" % "spray-client" % sprayVersion,
    "io.spray" %% "spray-json"  % "1.3.1",
    "com.typesafe.akka" %% "akka-actor" % akkaVersion,
    "com.typesafe.akka" %% "akka-slf4j" % akkaVersion,
    "com.typesafe.akka" %% "akka-testkit" % akkaVersion % "test",
    "ch.qos.logback" % "logback-classic" % "1.0.12",
    "org.scalatest" %% "scalatest" % "3.0.4" % "test"
  )
}

但是，在导入库时会生成以下错误。

[error] (*:update) Conflicting cross-version suffixes in: com.chuusai:shapeless, com.typesafe.akka:akka-actor, com.typesafe.akka:akka-testkit
[error] (*:ssExtractDependencies) Conflicting cross-version suffixes in: com.chuusai:shapeless, com.typesafe.akka:akka-actor, com.typesafe.akka:akka-testkit

建议合适的库，具有兼容性的高度赞赏。我使用的是Spark 2.2.0，Scala 2.11.11。

组合应该是：

libraryDependencies ++= Seq(
  "com.chuusai" %% "shapeless" % "2.3.1"
)

libraryDependencies ++= {
  val sprayVersion = "1.3.4"
  val akkaVersion = "2.5.4"
  Seq(
    "io.spray" %% "spray-can" % sprayVersion,
    "io.spray" %% "spray-routing" % sprayVersion,
    "io.spray" %% "spray-testkit" % sprayVersion,
    "io.spray" %% "spray-client" % sprayVersion,
    "io.spray" %% "spray-json"  % "1.3.3",
    "com.typesafe.akka" %% "akka-actor" % akkaVersion,
    "com.typesafe.akka" %% "akka-slf4j" % akkaVersion,
    "com.typesafe.akka" %% "akka-testkit" % akkaVersion % "test",
    "ch.qos.logback" % "logback-classic" % "1.0.12",
    "org.scalatest" %% "scalatest" % "3.2.0-SNAP7" % "test"
  )
}
