Unresolved dependencies in sbt 0.13.1 while building basic scala 2.12.8 project using akka 2.5.24

Well, I have to do a client-server program in Scala for my Computers Networks's class. I'm in the begginng, just trying to compile some hello world in Scala 2.12.8 using the akka 2.5.24 (because it has network facilities). But I'm having trouble with unresolved dependencies when I execute $ sbt run with sbt 0.13.1.

In this task, I'm trying to run just the code below in Fedora 30. I've already tried to change scala and akka versions, remove ~/.sbt and ~/.iv2 and use another sbt version (1.2.8). All of the attempts were unsuccessful. Below I show an attempt with sbt 0.13.1.

The scala code: 

import akka.actor.{ Actor, ActorRef, Props }
import akka.io.{ IO, Tcp }
import akka.util.ByteString
import java.net.InetSocketAddress

The sbt configuration:

name := "scala-transfer-file"

version := "0.1"

scalaVersion := "2.12.8"

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

libraryDependencies += "com.typesafe.akka" % "akka-actor" % "2.5.24"

I was just awaiting a sucess message or something, as it is just importation of packages. But what I'm getting is

Change

libraryDependencies += "com.typesafe.akka" % "akka-actor" % "2.5.24"

to

libraryDependencies += "com.typesafe.akka" %% "akka-actor" % "2.5.24"

This is clearly documented. The %% causes sbt to add the Scala version to the artifact name ("akka-actor").
