Description

This project [1] uses the maven-assembly-plugin to build fat JARs for the Camel applications it provides; if fat JARs are built and run they work perfectly.

I tried to add the camel-main dependency to the root pom and to the f1-telemetry-udp-kafka project pom as well, in order to change the application to use the Main class but I noticed that even if without using that class but just adding the camel-main in the pom, the JAR doesn't work anymore.

If you try to do so, doing a mvn package and then running

java -jar f1-telemetry-udp-kafka/target/f1-telemetry-udp-kafka-1.0-SNAPSHOT-jar-with-dependencies.jar

it fails with the following error:
