Error : java.lang.NoClassDefFoundError: akka/util/Timeout

Question

我想使用spray.io创建一个API，我遵循https://danielasfregola.com/2015/02/23/how-to-build-a-rest-api-with-spray/

之后，这是我的代码

package API.Configurations
import java.io.File
import com.typesafe.config.ConfigFactory
import akka.io.IO
import spray.can.Http
import akka.pattern.ask
import akka.util.Timeout
import scala.concurrent.duration._
import akka.actor.{ActorSystem, Props}
object MainServices
  extends App
{
  val configFile = new File("/home/ubuntu/conf/application.conf")
  val getPortMYSQL = ConfigFactory.parseFile(configFile).getInt("port")
  val getAddressMYSQL = ConfigFactory.parseFile(configFile).getString("address")
  val getUsernameMYSQL = ConfigFactory.parseFile(configFile).getString("username")
  val getPasswordMYSQL = ConfigFactory.parseFile(configFile).getString("password")
  val getPortAPI = ConfigFactory.parseFile(configFile).getInt("port_api")
  val getAddressAPI = ConfigFactory.parseFile(configFile).getString("address_api")
  val getPortES = ConfigFactory.parseFile(configFile).getInt("port_es")
  val getAddressES = ConfigFactory.parseFile(configFile).getString("address_es")
  val getclusterNameES = ConfigFactory.parseFile(configFile).getString("clusterNameES")
  implicit val system = ActorSystem("BRISK_API")
  val service = system.actorOf(Props[ServicesControllers], "CONFIGURATION_BRISK_API")
    import scala.concurrent.duration._
    implicit val askTimeout = new Timeout(5.seconds)
 // implicit val timeout = Timeout(5.seconds)
  IO(Http) ? Http.Bind(service, interface = getAddressAPI, port = getPortAPI)
  println(s"Detil Services MYSQL : Port = ${getPortMYSQL}, Address = ${getAddressMYSQL}, Username = ${getUsernameMYSQL}, Password = ${getPasswordMYSQL}")
  println(s"Detil Services API : Port = ${getPortAPI}, Address = ${getAddressAPI}")
  println(s"Detil Services ES : Port = ${getPortES}, Address = ${getAddressES}, ClusterName = ${getclusterNameES}")
}

当我尝试使用脚本：sbt运行时，我得到了错误。编译器说：

总是在akka/util/timeout，知道如何处理吗？谢谢

编辑1:我从那些链接被跟踪，但结果仍然和以前一样。使用Akka玩2.5-找不到参数超时的隐式值：Akka.util.timeout

编辑2:mybuild.sbt

Answer 1

build.sbt，添加一些代码，如下所示：

mergeStrategy in assembly := {
 case m if m.toLowerCase.endsWith("manifest.mf") => MergeStrategy.discard
 case m if m.toLowerCase.matches("meta-inf.*\.sf$") => MergeStrategy.discard
 case "reference.conf" => MergeStrategy.concat
 case _ => MergeStrategy.first
}

它对我很有效。
