The relations sink connector in https://github.com/project-kessel/kafka-relations-sink is built simply by `mvn clean package`. This is fine for local development, where the docker-compose file can pick up the local build in the target folder and mount it as a volume. However, for an OpenShift-based deployment, the artifacts need to be deployed and referenceable at a central location such as maven central. For example, the strimzi docs point to artifact locations in the `KafkaConnect` resources.

We already have a maven central repository for kessel, which members of the rebac team already have access to (you need to send them an email to add people to this namespace!): org.project-kessel. Go to https://central.sonatype.com/publishing/namespaces to view.

Tasks:

1. Determine if maven central is the correct location for the sink connector artifact. There's a chance we may need to build and host internally on Red Hat infra (see next point).
2. Determine whether we need to build and deploy the artifact using Konflux.
3. Assuming maven central is fine, the pom.xml plugin config for deploying there can be taken from https://github.com/project-kessel/relations-client-java/blob/main/pom.xml. 
4. Deploy a version 0.1 to maven central.

Definition of done:

• Sink connector plugin artifact is referenceable at the correct url for use in deployment specs.
