java.lang.NoClassDefFoundError debezium connector

Question

I am running kafka-connect in distributed mode. I have set up the plugin.path to where I installed debezium plugin.

I am getting java.lang.NoClassDefFoundError exception.

Properties file:

bootstrap.servers=10.X.X.X:9092
group.id=connect-cluster
key.converter=io.confluent.connect.avro.AvroConverter
key.converter.schema.registry.url=http://localhost:8081

internal.value.converter=org.apache.kafka.connect.json.JsonConverter
internal.key.converter.schemas.enable=false
internal.value.converter.schemas.enable=false
plugin.path=/usr/share/java,/root/mysql-plugin

Connector config:

{
  "name": "cdc.fkw.supply.payments_team5.payment.connector",
  "config": {
    "connector.class": "io.debezium.connector.mysql.MySqlConnector",
    "snapshot.locking.mode": "minimal",

    "errors.tolerance": "all",
    "database.whitelist": "payment",
    "snapshot.mode": "when_needed"
  },

After deploying a connector I get the following error,
