dynamodb plugins are not loaded

[fruch]

I'm running inside a docker in a ec2 instance,
and trying to use -Dndbench.config.cli.clientName=DynamoDBKeyValue from the command line ?

and keep hitting this error:

what am I doing wrong ?

also I want to try to use this with local dynamodb, as in the unit tests, but that's isn't clear on how to configured it from the commandline
