使用confluent docker all-in-one package，标签5.4.1；我正在努力使jdbc接收器连接器启动并运行。
启动以下连接器时：

{
  "name": "mySink",
  "connector.class": "io.confluent.connect.jdbc.JdbcSinkConnector",
  "value.converter": "org.apache.kafka.connect.json.JsonConverter",
  "topics": [
    "myTopic"
  ],
  "connection.url": "jdbc:sqlserver://sqlserver:1433;databaseName=myDB",
  "connection.user": "user",
  "connection.password": "**********",
  "dialect.name": "SqlServerDatabaseDialect",
  "insert.mode": "insert",
  "table.name.format": "TableSink",
  "pk.mode": "kafka",
  "fields.whitelist": [
    "offset",
    "value"
  ],
  "auto.create": "true"
}

（某些属性已编辑）
我从connect容器中得到以下异常： ERROR Plugin class loader for connector: 'io.confluent.connect.jdbc.JdbcSinkConnector' was not found. 对于connect，我有以下环境变量： CONNECT_PLUGIN_PATH: "/usr/share/java,/usr/share/confluent-hub-components" 如果我在集装箱登记，我有： /usr/share/java/kafka-connect-jdbc 包含以下文件：

./jtds-1.3.1.jar
./common-utils-5.4.0.jar
./slf4j-api-1.7.26.jar
./kafka-connect-jdbc-5.4.0.jar
./postgresql-9.4.1212.jar
./sqlite-jdbc-3.25.2.jar
./mssql-jdbc-8.2.0.jre8.jar
./mssql-jdbc-8.2.0.jre13.jar
./mssql-jdbc-8.2.0.jre11.jar

我对base connect映像所做的唯一更改是mssqljdbc驱动程序。对于jdbc源连接器来说，这些都可以正常工作。
要求的额外信息：
输出自 curl -s localhost:8083/connector-plugins|jq '.[].class' ```
