Quelle est la raison de Java.lang.NoSuchMethodError: scala.Predef $ .ArrowAssoc lors de l'exécution de "sbt test"?

J'ai rencontré l'erreur suivante lorsque j'essaie d'exécuter sbt test avec sbt 0.13.5 (et Java 1.7.0_45):

[erreur] (test: executeTests) Java.lang.NoSuchMethodError: scala.Predef $ .ArrowAssoc (Ljava/lang/Object;) Ljava/lang/Object;

Ceci est build.sbt j'utilise:

version := "0.1"

scalaVersion := "2.10.3"

resolvers ++= Seq(
  "spray" at "http://repo.spray.io",
  "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/"
)

libraryDependencies ++= Seq(
  "io.spray" %% "spray-json" % "1.2.5",
  "com.typesafe.akka" %% "akka-actor" % "2.2.4",
  "com.typesafe.akka" %% "akka-slf4j" % "2.2.4",
  "com.typesafe.akka" %% "akka-testkit" % "2.2.4",
  "com.github.kxbmap" %% "configs" % "0.2.1",

  "io.spray" % "spray-can" % "1.2.1",
  "io.spray" % "spray-routing" % "1.2.1",
  "io.spray" % "spray-testkit" % "1.2.1",
  "org.scalatest" % "scalatest_2.10" % "2.0" % "test",
  "com.typesafe.akka" %% "akka-testkit" % "2.1.4"% "test",
  "org.mockito" % "mockito-core" % "1.9.5",
  "org.specs2" %% "specs2" % "2.1.1" % "test"
)

J'ai essayé de supprimer les répertoires ~/.sbt et ~/.ivy2 et je faisais sbt clean après chaque.

C'est la trace de pile complète:

J'ai eu la même erreur et j'ai remarqué que sbt compilait scala 2.10 comme cible. Changer scalaVersion en 2.11.4 l'a résolu.

Effectuer ci-dessous à partir du dossier du projet,

  1. sbt propre 
  2. test de sbt

Cela fonctionnera comme un charme ...
