Webfleet Kafka Connector compilation

[GeoPamplona]

good morning
I'm trying to compile and run the connector in kafka
I had a doubt regarding the documentation; it specifies that "schema registry" is necessary, but how is it configured with the connector?
Is any additional configuration necessary to use the connector?

I compile the connector with the following command lines:
sbt
run build

However, after compiling I get the following error:

sbt: webfleedKafkaConnector> run build

and generates the file webfleedkafkaconnector_2.12-0.0.1.jar
Should I generate another additional file?

I use this file in kafka-connect but it does not recognize it as a connector

Also in the configuration webfleet parameters, should not include the api key?

Thank you

edit 22/03/2018:
it is impossible for me to correctly install the connector
kafka-conect does not recognize it or load it
Could you distribute a new compiled release, ready to be used?

thanks !
