Jakub Scholz created KAFKA-13839:
------------------------------------
Summary: Example connectors Maven artifact should use provided
dependencies
Key: KAFKA-13839
URL: https://issues.apache.org/jira/browse/KAFKA-13839
Project: Kafka
Issue Type: Bug
Reporter: Jakub Scholz
The {{connect-file}} artifact which contains the sample
{{FileStreamSourceConnector}} and {{FileStreamSourceConnector}} connectors has
currently 2 Maven dependencies:
* {{connect-api}}
* {{slf4j}}
Both are marked as runtime dependencies. So when the connectors are pulled from
Maven repository to be added to the plugin path, they pull with them also these
dependencies and other transitive dependencies (such as {{{}kafka-clients{}}}).
This seems unnecessary since all these dependencies are already in the
classpath of Kafka itself and do not need to be there again in the plugin path.
They should be configured as {{provided}} so that they are not downloaded with
the connectors.
This is now more relevant after
https://issues.apache.org/jira/browse/KAFKA-13748, when the connectors are not
anymore on the main classpath and downloading them from Maven to the plugin
path would be more common.
