SBT 未解决与 Akka 的依赖关系

Question

我对 Scala、Akka 和 SBT 还很陌生，所以这个问题让我有些头疼！我正在使用 Akka in Action 一书，作者在 Github 上提供了示例： https://github.com/RayRoestenburg/akka-in-action 在存储库的干净克隆上，我试图查看 chapter-cluster 中的示例。

如书中所述，首先要做的是在本地机器上启动一个种子节点：

sbt -DHOST=127.0.0.1 -DPORT=2551

我试图安装另一个 Scala 版本，以 root 权限运行它，但没有成功。据我了解，SBT 应该负责所有版本控制并下载指定的包。

错误信息是这样的：

更新 1： 这是 build.sbt 文件的内容：

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"

知道出了什么问题吗？

Answer 1

试试这个作为你的 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 scala、日志和 scalatest 版本

Answer 2

似乎我使用的 sbt 版本是错误的！升级到 sbt-0.13.15 后编译运行正常。

感谢您的帮助！
