hi all
this is my code :
https://github.com/SalmaKhater/Learning-Akka/tree/master/akka-cluster/src/main/scala/load-balancing
and this is my config files in project :
https://github.com/SalmaKhater/Learning-Akka/tree/master/akka-cluster/src/main/resources
and my sbt file this :
name := "Akka"
version := "1.0"
scalaVersion := "2.12.2"
libraryDependencies ++= Seq(
"com.typesafe.akka" %% "akka-actor" % "2.5.1",
"com.typesafe.akka" %% "akka-remote" % "2.5.1",
"com.typesafe.akka" %% "akka-cluster" % "2.5.1",
"com.typesafe.akka" %% "akka-cluster-sharding" % "2.5.1",
"com.typesafe.akka" %% "akka-cluster-tools" % "2.5.1",

)
but when i run project i've got this error :
Exception in thread "main" java.lang.IllegalArgumentException: Cannot

sure it extends [interface akka.routing.RouterConfig] and has constructor with
