I'm testing the salesforce component (streaming API) across different versions of camel (2.17.4/2.23.0). In 2.23.0 I got an example running using spring (based on camel/examples/camel-example-twitter-salesforce at master · apache/camel · GitHub ):

SalesforceLauncher.java

package org.apache.camel.example.mention;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


//CHECKSTYLE:OFF
@SpringBootApplication
public class SalesforceLauncher {


    /**
     * A main method to start this application.
     */
    public static void main(String[] args) {
        SpringApplication.run(SalesforceLauncher.class, args);
    }


}
//CHECKSTYLE:ON

SalesforceRoute.java

import org.apache.camel.builder.RouteBuilder;
import org.springframework.stereotype.Component;


@Component
public class SalesforceRoute extends RouteBuilder {


    @Override
    public void configure() throws Exception {
        from("salesforce:UpdateAccount?notifyForFields=ALL&notifyForOperations=ALL").tracing().convertBodyTo(String.class).to("file:D:/tmp/work/").log("SObject ID: ${body}");
    }
}

and pom.xml:

Moving the example to 2.17.4 generates:

Failed to create route route1: Route(route1)[[From[salesforce:All_Account_Change?notifyForF... because of Failed to resolve endpoint: salesforce://All_Account_Change?notifyForFields=ALL&notifyForOperations=ALL due to: No component found with scheme: salesforce

This persists even if the salesforce component is added to the pom (the component from 2.17.4). A maven build shows the following output:

What would be a minimalist (preferably without using spring) salesforce streaming client (with no DTOs needed (only fetching updates from Salesforce))?
