Solved: Webserver with kafka producer

Hi,

found the solution: I have to exclude a bad dependency from kafka:

compile( group: 'org.apache.kafka', name: 'kafka_2.11', version: '0.11.0.2' ) {
    exclude group: 'org.scala-lang.modules', module: 'scala-parser-combinators_2.11'
}    

Akka loads “scala-parser-combinators_2.12” that works with KAFKA, too.

Have a nice day

Martin
