Development & Contributions

Build locally

Make sure you install dip and direnv.

For the end-to-end tests, you need to provision a local Kafka cluster, Kafka Connect instance and a Neo4j server. This is done by running (re-running recreates the containers):

dip provision

Make sure direnv exports environment variables by running:

direnv allow .

You can build and package the project using (as many as time as necessary):

mvn verify

You'll find the connector archive at packaging/target/neo4j-kafka-connect-{version}.zip.

Code Format

TL;DR? You can run dip format.

For Kotlin code, we follow the ktfmt code style. There is an .editorconfig file to mimic the underlying style guides for built-in Intellij code style rules, but we recommend ktfmt IntelliJ Plugin for formatting. Remember that your builds will fail if your changes doesn't match the enforced code style, but you can use ./mvnw spotless:apply to format your code.

For POM files, we are using sortpom to have a tidier project object model. Remember that your builds will fail if your changes doesn't conform to the enforced rules, but you can use ./mvnw sortpom:sort to format it accordingly.
