Suffixes de version croisée en conflit

Question

Voici une section du fichier build.sbt que j'ai récemment ajouté à mon projet pour créer une API pour l'application.

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" 
) 
} 

Bien que, lors de l'importation des bibliothèques, les erreurs suivantes soient générées.

[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 

Une suggestion pour les bibliothèques appropriées, ayant une compatibilité est hautement appréciée. J'utilise Spark 2.2.0, Scala 2.11.11.

La combinaison doit être:

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" 
) 
}
