-This will build the connector from source and create a local image with an aggregate version number.  The aggregate version number is the kafka-connect-datagen connector version number and the Confluent Platform version number separated with a `-`.   The local kafka-connect-datagen version number is defined in the `pom.xml` file, and the Confluent Platform version defined in the [Makefile](Makfile).
