[lvchongyi]

kafka-2.5.0+flink-1.10.1+janusgraph-0.5.2
Real time data import tips org.apache.flink . streaming.connectors.kafka . flinkkafkaconsumer class does not exist,

But flink-connector-kafka_2.12-1.10.1.jar and flink-connector-kafka-base_2.12-1.10.1.jar is already in the POM dependency.

What's the matter, please?

this is log detail....
