missing connector libraries in cp-kafka-connect docker image

[electriquo]

using cp-kafka-connect version 5.5.2 i successful set connectors (s3, elasticsearch, etc.). after upgrading to version 6.0.1, when i try to enable the connectors, i get the following error

Failed to find any class that implements Connector and which name matches io.confluent.connect.elasticsearch.ElasticsearchSinkConnector, available connectors are ...

digging into the containers of each of which, it seems that some connect libraries are missing from /usr/share/java/kafka-connect-*

$ docker run --rm -it confluentinc/cp-kafka-connect:5.5.2 \
    /bin/bash -c 'ls -x1 -d /usr/share/java/kafka-connect-*'
/usr/share/java/kafka-connect-activemq
/usr/share/java/kafka-connect-elasticsearch
/usr/share/java/kafka-connect-ibmmq
/usr/share/java/kafka-connect-jdbc
/usr/share/java/kafka-connect-jms
/usr/share/java/kafka-connect-s3
/usr/share/java/kafka-connect-storage-common

$ docker run --rm -it confluentinc/cp-kafka-connect:6.0.1 \
    /bin/bash -c 'ls -x1 -d /usr/share/java/kafka-connect-*'
ls: cannot access '/usr/share/java/kafka-connect-*': No such file or directory

1. it this intended?
2. what is the shortest path to upgrade to version 6.0.1?

just saw the deprecation notice.

still trying to figure out how to upgrade to latest s3 connect docker image

downloaded the plugins of s3 and elasticsearch, then followed installing kafka connect plugins
