> Hi
> I see there's a missalingment between the features dependencies and the pom
> of the camel-kafka component that makes impossible to run a Producer in
> karaf. I can see that in the features.xml
> {code:xml}
> <bundle
> dependency='true'>mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.kafka-clients/${kafka-clients-bundle-version}</bundle>
> <bundle
> dependency='true'>mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.kafka_2.10/${kafka-bundle-version}</bundle>
> {code}
> It's trying to use 2.10 scala version, but in the pom.xml we point to 2.11
> scala version
> {code:xml}
> <dependency>
> <groupId>org.apache.kafka</groupId>
> <artifactId>kafka_2.11</artifactId>

> producer, but the consumer is ok.
