> Key: CAMEL-16419
> URL: https://issues.apache.org/jira/browse/CAMEL-16419
> Project: Camel
> Issue Type: Bug
> Components: camel-main
> Affects Versions: 3.8.0
> Reporter: Paolo Patierno
> Priority: Major
>
> 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
> {code:java}
> java -jar
> f1-telemetry-udp-kafka/target/f1-telemetry-udp-kafka-1.0-SNAPSHOT-jar-with-dependencies.jar
> {code}
> it fails with the following error:
> {code:java}
