Failed to find any class that implements Connector and which name matches io.confluent.connect.jdbc.JdbcSourceConnector

[javaHelper]

I am using Confluent Kafka community edition locally on mac machine.

ksql> CREATE SOURCE CONNECTOR `postgres-jdbc-source` WITH (
>   "connector.class"='io.confluent.connect.jdbc.JdbcSourceConnector',
>   "connection.url"='jdbc:postgresql://postgres:5432/postgres',
>   "mode"='incrementing',
>   "incrementing.column.name"='ref',
>   "table.whitelist"='carusers',
>   "connection.password"='postgres',
>   "connection.user"='postgres',
>   "topic.prefix"='db-',
>   "key"='username');

Getting below error
