Nessuna configurazione impostazione trovato per la chiave 'akka.version'

Question

sto imparando Akka-servizi remoti e questo è come il mio progetto appare

La struttura del progetto si presenta come

project/pom.xml 
project/mymodule/pom.xml 
project/mymodule/src/main/resources/application.conf 
project/mymodule/src/main/scala/com.harit.akkaio.remote.RemoteApp.scala 
project/mymodule/src/main/scala/com.harit.akkaio.remote.ProcessingActor.scala 

Quando eseguo il mio progetto su command-line , vedo

$ java -jar akkaio-remote/target/akka-remote-jar-with-dependencies.jar com.harit.akkaio.remote.RemoteApp 
Hello:com.harit.akkaio.remote.RemoteApp

Che cosa mi manca fuori? Grazie

Answer 1

Sembra che il problema sia bundling in un jar-with-dependencies, che causa problemi con Akka, come descritto nella documentation:

Attenzione

approccio di configurazione di Akka si basa molto sul concetto di ogni modulo/jar con il proprio file reference.conf, tutti verranno scoperti dalla configurazione e caricati. Sfortunatamente questo significa anche che se metti/unisci più jar nello stesso jar, devi unire anche tutti i reference.confs. Altrimenti tutte le impostazioni predefinite andranno perse e Akka non funzionerà.

Come suggerito sulla stessa pagina, è possibile utilizzare maven-shade-plugin per unire tutte le configurazioni di riferimento:

se si utilizza Maven per confezionare la vostra applicazione, si può anche fare uso di Shade Apache Maven Supporto plug-in per Resource Transformers per unire tutti i reference.confs sul classpath di build in uno solo.

Vedi anche: Akka: missing akka.version

Answer 2

avuto un problema simular:

com.typesafe.config.ConfigException$Missing: 
No configuration setting found for key 'akka.persistence.journal-plugin-fallback' 

risolto con l'aggiunta di un trasformatore aggiungendo:

<plugin> 
    <artifactId>maven-shade-plugin</artifactId> 
    <version>2.4.1</version> 
    <executions> 
    <execution> 
     <phase>package</phase> 
     <goals> 
     <goal>shade</goal> 
     </goals> 
     <configuration> 
     <transformers> 
      <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> 
      <resource>reference.conf</resource> 
      </transformer> 
     </transformers> 
     </configuration> 
    </execution> 
    </executions> 
</plugin> 

Answer 3

calcolata AppendingTransformer solo non ha risolto il problema per me. Se si sta provando a distribuire l'applicazione spark su EMR e si sta ancora affrontando questo problema, si prega di dare un'occhiata alla mia soluzione here. Spero che sia d'aiuto!
