Akka actor logging not writing to file

I'm attempting to log to a file rather than stdout.

My application.conf (in src/main/resources/):

akka {
  event-handlers = ["akka.event.slf4j.Slf4jEventHandler"]
  loglevel = "DEBUG"
}

logback.xml (in src/main/resources/):

<configuration>

    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <file>log/app.log</file>
        <append>true</append>
        <encoder>
            <pattern>%date{yyyy-MM-dd} %X{akkaTimestamp} %-5level[%thread] %logger{1} - %msg%n</pattern>
        </encoder>
    </appender>

    <root level="DEBUG">
        <appender-ref ref="FILE"/>
    </root>
</configuration>

Creating the actor system:

val conf: Config = ConfigFactory.load()
val system = ActorSystem("Process", conf)

Finally, the actual logging:

class Processor() extends Actor with ActorLogging {
   def receive = {
      case Start =>
         log.info("Started")
   }
}

However, when running the app, I get the logging in stdout:

[info] Running com.imgzine.analytics.apps.ProcessEvents
[DEBUG] [06/02/2014 09:28:53.356] [run-main] [EventStream(akka://Process)] logger log1-Logging$DefaultLogger started
[DEBUG] [06/02/2014 09:28:53.358] [run-main] [EventStream(akka://Process)] Default Loggers started
[INFO] [06/02/2014 09:28:53.389] [Process-akka.actor.default-dispatcher-4] [akka://Process/user/processor] Started
[DEBUG] [06/02/2014 09:28:54.887] [Process-akka.actor.default-dispatcher-4] [EventStream] shutting down: StandardOutLogger started

And inside log/app.log, I find:

2014-06-02  DEBUG[ProcessEvents-akka.actor.default-dispatcher-2] c.m.c.c.c.s.RegisterConversionHelpers$ - Registering Scala Conversions.

Any ideas?

If you are using Akka 2.3.3 as stated in response to my comment, then your config around logging is out of date (using old logging config setup). Try replacing your logging config with:

akka {
  loggers = ["akka.event.slf4j.Slf4jLogger"]
  loglevel = "DEBUG"
}

If that does not work let me know and I'll advise on another solution.
