To Reproduce
Steps to reproduce the behavior:

1. clone https://github.com/lburgazzoli/apache-camel-k-runtime/tree/github-57
2. build the project
3. go to camel-k-runtime-examples/camel-k-runtime-example-quarkus-yaml
4. run mvn clean compile quarkus:dev

If you using mvn compile quarkus:dev inside a multi-module maven project that also contains an extension you need to use mvn compile quarkus:dev -DnoDeps to exclude the local project dependencies from the dev mode. Otherwise, quarkus attempts to monitor the extension classes and this results in various classloading issues.

See https://github.com/quarkusio/quarkus/blob/master/devtools/maven/src/main/java/io/quarkus/maven/DevMojo.java#L137-L142.

FYI I've just sent a PR to mention this property in the extension guide.
