Kafka Connect: No suitable driver found

I am trying Kafka with Postgres Sink using JDBC-sink connector.

Exception:

INFO Unable to connect to database on attempt 1/3. Will retry in 10000 ms. (io.confluent.connect.jdbc.util.CachedConnectionProvider:91)
java.sql.SQLException: No suitable driver found for jdbc:postgresql://localhost:5432/casb

Sink.properties:

name=test-sink
connector.class=io.confluent.connect.jdbc.JdbcSinkConnector
tasks.max=1
topics=fp_test
connection.url=jdbc:postgresql://localhost:5432/casb
connection.user=admin
connection.password=***
auto.create=true

I have set plugin.path=/usr/share/java/kafka-connect-jdbc

On /usr/share/java/kafka-connect-jdbc I have the following files:

kafka-connect-jdbc-4.0.0.jar , postgresql-9.4-1206-jdbc41.jar, sqlite-jdbc-3.8.11.2.jar and some other jars that basically come packaged along with confluent.

I then downloaded postgres-jdbc driver jar postgresql-42.2.2.jar, copied it in the same folder and tried again. Still the same exception.

Kindly help me out with this.

Setting plugin.path=/usr/share/java and CLASSPATH=/usr/share/java/kafka-connect-jdbc/ solved the issue.
