URL: https://github.com/apache/camel-k/issues/1579#issuecomment-651809029
What I am trying to do is have a working application using Camel K. I have
managed to do a Java only application. What I would now want to do is rewrite
the Camel integration in Yaml.
Some initial features that I want to exercise are:
1. sending HTTP requests to some third-party service and getting a response
2. have a custom processor to process that response
I would like to do this from YAML to see how that can be done using YAML
instead of Camel Java code.
In this particular issue I am trying to handle point 2.
It seems that the problematic part is being able to include processor part.
This is my call right now after you telling me that the --property is not
required:
```
kamel run --name=test routes.yaml RegistryConfigurer.java --dev
```
routes contains this:
```
- from:
uri: "timer:clock"
parameters:
period: "1000"
steps:
- set-body:
constant: "foo"
- process:
ref: "myProcessor"
- to: log:info
```
Registry configurer file contains this:
```
...
class MyProcessor implements Processor {
void public process(...) {
...
}
}
public class RegistryConfigurer {
@BindToRegistry
public MyProcessor myProcessor() {
return new MyProcessor();
}
}
```
After eliminating the `--property` flag from the kamel run CLI, I get the
following error. Can this error be fixed if I publish my class in a maven repo?
