Cannot load plugin crashes kafka connect as unable to find dependancies.

[bob9]

After adding plugin seems to fail to find dependancies.. Other plugins working on the kafka connect server running confluent 5.0.0 installed via confluent helm package..

Thats the Dockerfile i am using to create the kafka connect docker image.

Any help would be appreciated. I used the 0.1.2 version in releases had so luck so compiled it fresh however still had not luck with local compiled version.

FROM confluentinc/cp-kafka-connect:5.0.0
