scala - Akka中 Unresolved 依赖项错误

Question

嗨，我是akka的新手，我正在尝试开发示例akka应用程序
但是，当我在shell上执行运行命令时，它会给我 Unresolved 依赖项警告，然后显示错误

这是我的Main.scala文件

import akka.actor.Actor
import akka.actor.ActorSystem
import akka.actor.Props
 
class HelloActor extends Actor {
  def receive = {
    case "hello" => println("hello back at you")
    case _       => println("huh?")
  }
}
 
object Main extends App {
  val system = ActorSystem("HelloSystem")
  // default Actor constructor
  val helloActor = system.actorOf(Props[HelloActor], name = "helloactor")
  helloActor ! "hello"
  helloActor ! "buenos dias"
}

build.sbt

name := "tryakka"

version := "1.0"

scalaVersion := "2.11.1"

resolvers += "Typesafe Repository" at "http://repo.typesafe.com/typesafe/releases/"

libraryDependencies += "com.typesafe.akka" %% "akka-actor" % "2.3.4"

以下是警告和错误

提前致谢

Answer 1

当前，您需要的依赖项是:

libraryDependencies += "com.typesafe.akka" % "akka-actor_2.11" % "2.3.4"

它是为Scala 2.11版而非2.11.1版构建的。您的依赖项使用 %%替代了构建中设置的Scala版本，因此出现错误-您的URL包含次要版本，并且该资源不存在。

更新:

我创建了一个小项目，其中包含可编译和运行的代码。在这里查看: https://github.com/izmailoff/SmallAkkaProjectExample
