Re: Managing Quarkus dependencies when working with Native build

[Vladislav Krejcirik]

Thanks for quick response! I do need reflection for my class. Please see my 
dummy Integration below. When I removed annotation, it was not able to find my 
‘getRandomNumber’ method.  When I added annotation, it worked just fine, but my 
VS Code was complaining about missing Quarkus dependency. 

Thanks,
Vlad

import org.apache.camel.builder.RouteBuilder;

import io.quarkus.runtime.annotations.RegisterForReflection;

@RegisterForReflection
public class Demo05 extends RouteBuilder {

    @Override
    public void configure() throws Exception {

        // Write your routes here, for example:
        from("timer:java?period={{time:1000}}")
            .id("demo05")
            .bean(this, "getRandomNumber")
            .log("Random number: ${body}")
            .choice()
                .when(simple("${body} > 50"))
                    .to("direct:greater")
                .otherwise()
                    .to("direct:lower");

        from("direct:greater")
            .log("Greater than 50: ${body}");

        from("direct:lower")
            .log("Lower than 50: ${body}");
    }

    public int getRandomNumber() {
        return (int) (Math.random() * 100) + 1;
    }
}
