Classic Actors

Note

Akka Classic pertains to the original Actor APIs, which have been improved by more type safe and guided Actor APIs. Akka Classic is still fully supported and existing applications can continue to use the classic APIs. It is also possible to use the new Actor APIs together with classic actors in the same ActorSystem, see coexistence. For new projects we recommend using the new Actor API.

Dependency

The Akka dependencies are available from Akka’s library repository. To access them there, you need to configure the URL for this repository.

sbt

resolvers += "Akka library repository".at("https://repo.akka.io/maven")

Maven

<project>
  ...
  <repositories>
    <repository>
      <id>akka-repository</id>
      <name>Akka library repository</name>
      <url>https://repo.akka.io/maven</url>
    </repository>
  </repositories>
</project>

Gradle

repositories {
    mavenCentral()
    maven {
        url "https://repo.akka.io/maven"
    }
}

To use Classic Akka Actors, you must add the following dependency in your project:

sbt

val AkkaVersion = "2.10.0+14-bc29c0c3-SNAPSHOT"
libraryDependencies ++= Seq(
  "com.typesafe.akka" %% "akka-actor" % AkkaVersion,
  "com.typesafe.akka" %% "akka-testkit" % AkkaVersion % Test
)

Maven
