Support / Feedback

For issues with, questions about, or feedback for the MongoDB Kafka Connector, please look into our support channels. Please do not email any of the developers directly with issues or questions - you're more likely to get an answer on the mongodb-user discussion forum.

At a minimum, please include in your description the exact version of the driver that you are using. If you are having connectivity issues, it's often also useful to paste in the Kafka connector configuration. You should also check your application logs for any connectivity-related exceptions and post those as well.

The MongoDB Kafka Connector follows semantic versioning. See the changelog for information about changes between releases.


Note: The following instructions are intended for internal use.

Java 8+ is required to build and compile the source. To build and test the driver:

$ git clone
$ cd mongo-kafka
$ ./gradlew check -Dorg.mongodb.test.uri=mongodb://localhost:27017

The test suite requires mongod to be running. Note, the source connector requires a replicaSet.

IntelliJ IDEA

A couple of manual configuration steps are required to run the code in IntelliJ:

  • Error: java: cannot find symbol. symbol: variable Versions
    Fixes: Any of the following:
    • Run the compileBuildConfig task: eg: ./gradlew compileBuildConfig or via Gradle > mongo-kafka > Tasks > other > compileBuildConfig
    • Set compileBuildConfig to execute Before Build. via Gradle > Tasks > other > right click compileBuildConfig - click on "Execute Before Build"
    • Delegate all build actions to Gradle: Settings > Build, Execution, Deployment > Build Tools > Gradle > Runner - tick "Delegate IDE build/run actions to gradle"
You can’t perform that action at this time.
