Kafka Tutorial #1

I’ve been having issues with this tutorial. When I get to step 6 and try to issue this command
java -cp target/Tutorial-1.0-SNAPSHOT.jar tutorial1.TruckEventsProducer localhost:9092 localhost:2181 &

I get this error
Error: Could not find or load main class tutorial1.TruckEventsProducer

I’ve not had any failed commands up to this point and java is not my native language. Any help given would be appreciated.
