Servicemix simple bundle missing requirement

Question

Hello I am new to servicemix and cannot start a simple self-programmed bundle.

My pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"                           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

My camel-context.xml

<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:camel="http://camel.apache.org/schema/spring"
  xsi:schemaLocation="

  http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

<camelContext id="Merda" xmlns="http://camel.apache.org/schema/spring">
    <packageScan>
         <package>de.rupp</package>
     </packageScan>
 </camelContext>
 </beans>

I only have one simple class

public class TestRoute extends RouteBuilder {

@Override
public void configure() throws Exception {
    from("file:in")
        .id("file-in")
        .log("Nachricht: ${body}")
        .to("file:out");

}

}

The resulting MANIFEST.MF is

Manifest-Version: 1.0
Bnd-LastModified: 1560848195732
Build-Jdk: 1.8.0_181
Built-By: bla
Bundle-ManifestVersion: 2
Bundle-Name: test
Bundle-SymbolicName: test
Bundle-Version: 1.0.0.SNAPSHOT
Created-By: Apache Maven Bundle Plugin
Export-Package: de.rupp;uses:="org.apache.camel.builder,org.apache.camel
 .model";version="1.0.0.SNAPSHOT"
Import-Package: org.apache.camel.builder;version="[3.0,4)",org.apache.ca
 mel.model;version="[3.0,4)"
Tool: Bnd-1.50.0

when I copy the jar to the deploy folder and use bundle:list I see it installed 225 | Installed | 80 | 1.0.0.SNAPSHOT | test

However I cannot start it.

karaf@root>start 225

Error executing command: Error executing command on bundles:
        Error starting bundle 225: Unable to resolve test [225](R 225.14): missi
ng requirement [test [225](R 225.14)] osgi.wiring.package; (&(osgi.wiring.packag

rements: [[test [225](R 225.14)] osgi.wiring.package; (&(osgi.wiring.package=org
.apache.camel.builder)(version>=3.0.0)(!(version>=4.0.0)))]

Any help would be greatly appreciated. Does anyone know a good tutorial for writing camel bundles?

Thanks,

Hans

You should use the Camel version that ServiceMix is using (ships with out of the box). ServiceMix does NOT support Camel 3.

Also I wonder suggest to look at just using Apache Karaf or alternative runtimes for Camel (Spring Boot, Quarkus, Tomcat, Standalone Camel via Camel Main) as ServiceMix is not so active anymore.
