        |  test - runs all the tests for all of the connectors.
        |    Make sure to run `docker-compose up` first.
        |
        |  mqtt/testOnly *.MqttSourceSpec - runs a single test
        |
        |  mimaReportBinaryIssues - checks whether this current API
        |    is binary compatible with the released version
