I think the problem is here.

No implementors of QuarkusApplication are found, so Quarkus does not know which main class to run. I think we can fix it by adding a new BuildStep to the main extension, so that CamelMainApplication is indexed. E.g:

AdditionalIndexedClassesBuildItem(CamelMainApplication.class.getName())

Until then, the workaround is to manually index camel-quarkus-main by setting properties in application.properties:

quarkus.index-dependency.camel-quarkus-main.group-id=org.apache.camel.quarkus
quarkus.index-dependency.camel-quarkus-main.artifact-id=camel-quarkus-main

Or you can tweak the QuarkusMain annotation to:

@QuarkusMain(name = "org.apache.camel.quarkus.main.CamelMainApplication")
