Scala - Build SBT - Caused by: com.typesafe.config.ConfigException$Missing: No configuration setting found for key 'akka.version'

Question

I am getting following error while running my akka project using built using build.sbt.

    Exception in thread "main" java.lang.ExceptionInInitializerError
        at com.airwave.feeder.FeederApp.main(FeederApp.scala)

My application.conf looks like following:
cat src/main/resources/application.conf 
akka {
    stdout-loglevel = "OFF"                 // supress console logging
    loglevel = "DEBUG"                      // use INFO as default
    loggers = ["akka.event.slf4j.Slf4jLogger"]
    logging-filter = "akka.event.slf4j.Slf4jLoggingFilter"
    lower-bound = 5
    upper-bound = 100
}

I am using sbt for building my fat jar. Do I need to modify build.sbt file?

Thanks
