SBT未解決的依存與Akka

我對Scala，Akka和SBT相當陌生，所以這個問題讓我頭疼！我的書阿卡在行動，在這裏筆者提供了Github上的示例工作： https://github.com/RayRoestenburg/akka-in-action 在倉庫的一個乾淨克隆，我試圖在章集羣看看例子。SBT未解決的依存與Akka

正如書中所描述的，做的第一件事就是啓動一個種子節點的本地機器上：

sbt -DHOST=127.0.0.1 -DPORT=2551

我試圖安裝其他的Scala版本，以root權限運行它，但沒有成功。在我的理解SBT應該照顧所有版本的東西，並下載指定的軟件包。

錯誤消息是這樣說：

更新1： 這是build.sbt文件的內容：

name := "words-cluster" 

version := "1.0" 

scalaVersion := "2.11.7" 

organization := "com.manning" 

libraryDependencies ++= { 
    val akkaVersion = "2.4.14" 
    Seq(
    "com.typesafe.akka"  %% "akka-actor"      % akkaVersion, 
    "com.typesafe.akka"  %% "akka-slf4j"      % akkaVersion, 
    "com.typesafe.akka"  %% "akka-remote"      % akkaVersion, 
    "com.typesafe.akka"  %% "akka-cluster"      % akkaVersion, 
    "com.typesafe.akka"  %% "akka-multi-node-testkit"   % akkaVersion % "test", 
    "com.typesafe.akka"  %% "akka-testkit"      % akkaVersion % "test", 
    "org.scalatest"   %% "scalatest"       % "3.0.0"  % "test", 
    "com.typesafe.akka"  %% "akka-slf4j"      % akkaVersion, 
    "ch.qos.logback"   % "logback-classic"     % "1.0.10" 
) 
} 

// Assembly settings 
mainClass in Global := Some("aia.cluster.words.Main") 

assemblyJarName in assembly := "words-node.jar"

任何想法是怎麼回事？

你可以給我們你的build.sbt文件嗎？ –

我在原帖中做了更新！ –

「org.scalatest」％「scalatest_2.11」％「3.0.0」試試這個依賴而不是scalatest。 – Nilesh

好像我是用了錯誤的一個SBT版本！升級到sbt-0.13.15編譯後，運行正常。

感謝您的幫助！

試試這個作爲你的build.sbt：

name := "words-cluster" 

version := "1.0" 

scalaVersion := "2.11.8" 

organization := "com.manning" 

libraryDependencies ++= { 
    val akkaVersion = "2.4.14" 
    Seq(
    "com.typesafe.akka"  %% "akka-actor"      % akkaVersion, 
    "com.typesafe.akka"  %% "akka-slf4j"      % akkaVersion, 
    "com.typesafe.akka"  %% "akka-remote"      % akkaVersion, 
    "com.typesafe.akka"  %% "akka-cluster"      % akkaVersion, 
    "com.typesafe.akka"  %% "akka-multi-node-testkit"   % akkaVersion % "test", 
    "com.typesafe.akka"  %% "akka-testkit"      % akkaVersion % "test", 
    "org.scalatest"   %% "scalatest"       % "3.0.1"  % "test" exclude("org.scala-lang.modules", "scala-xml_2.11"), 
    "com.typesafe.akka"  %% "akka-slf4j"      % akkaVersion, 
    "ch.qos.logback"   % "logback-classic"     % "1.1.7" 
) 
} 

// Assembly settings 
mainClass in Global := Some("aia.cluster.words.Main") 

assemblyJarName in assembly := "words-node.jar"

我更新了斯卡拉，記錄和scalatest版本

更改爲「1.1.7」後，我收到了完全相同的錯誤消息！ –

嗨我編輯我的答案，請嘗試以下build.sbt –

不，我很抱歉，但錯誤仍然存在以相同的方式。 –
