Auto-discover/load RouteBuilder from Maven dependency (Jar)

Hi,

Topic from Zulip: #camel-k > Auto-discover/load RouteBuilder from Maven dependency (Jar)

I have some Java Camel routes packaged in a Maven artifact that I would like to run in my integrations.

Specs:

• Camel K: 2.9.0

• Repository: Nexus (private maven repo)

Current Workaround: To start the routes, I have to use an additional "loader" Java class to manually wire them:

import org.apache.camel.builder.RouteBuilder;
import org.tnt.camel.MyRouteBuilder;

public class Loader extends RouteBuilder {
  @Override
  public void configure() throws Exception {
      getContext().addRoutes(new MyRouteBuilder());
  }
}

The Java route inside my Maven artifact looks like this:

package org.tnt.camel;

import org.apache.camel.builder.RouteBuilder;

public class MyRouteBuilder extends RouteBuilder {
    public void configure() {
        from("timer:test")
                .setBody().constant("Hi from jar!")
                .log("${body}");
    }
}

I run this integration using the following command:

kamel run Loader.java test.camel.yaml --name test-mvn -d mvn:org.tnt.camel:tnt-camel:1.0.0

The Question: All works good, but I was wondering if there is an alternative way to tell Camel K to auto-discover or scan for routes in the classpath at runtime?

I am looking for something similar to camel.main.routes-include-pattern so I can just point to the JAR and avoid writing the Loader.java wrapper class.
