[error] (*:update) sbt.ResolveException: unresolved dependency: com.typesafe.akka#akka-sbt-plugin;2.0: not found

Я использую sbt версии 0.13.8 и Scala 2.11.4.

Это файл build.sbt

name := "test"

version := "1.0"

scalaVersion := "2.11.7"

libraryDependencies ++= {
  val akkaV = "2.3.14"
  val sprayV = "1.3.1"
  Seq (
"joda-time" % "joda-time" % "2.9.1",
"com.typesafe.akka" %% "akka-actor"   % akkaV,
"com.typesafe.akka" %% "akka-slf4j"   % akkaV,
"com.typesafe.akka" %% "akka-remote"  % akkaV,
"com.typesafe.akka" %% "akka-agent"   % akkaV,
"com.typesafe.akka" %% "akka-sbt-plugn" % akkaV,
"com.typesafe.akka" %% "akka-testkit" % akkaV % "test"
  )
}

resolvers ++= Seq(
  "Spray repository" at "http://repo.spray.io",
  "Typesafe repository" at "http://repo.akka.io/releases/",
  "Akka Snapshot Repository" at "http://repo.akka.io/snapshots/",
  "Typesafe repository" at "https://repo.typesafe.com/typesafe/releases/",
  "Scala-Tools Maven2 Snapshots Repository" at "http://scala-tools.org/repo-snapshots"
)

Revolver.settings: Seq[sbt.Setting[_]]

А это plugins.sbt

logLevel := Level.Warn

addSbtPlugin("io.spray" % "sbt-revolver" % "0.8.0")

addSbtPlugin("com.typesafe.akka" % "akka-sbt-plugin" % "2.0")

В настоящее время я использую intellij. Он отлично работал со спреем и joda-time, но начались проблемы, когда был добавлен akka.
