请教flink-sql-iotdb-connector连接器写入iotdb的sql案例

请问下: 看文档介绍从1.2开始支持flinksql的连接器了，但是无法引入该jar

```

org.apache.iotdb
flink-sql-iotdb-connector
${iotdb.version}

```
maven仓库没有该jar？这个jar如何引入。

另外，flink-sql-iotdb-connector 的sql形式案例有没有？例如：
```
`-- register a MySQL table 'users' in Flink SQL
CREATE TABLE MyUserTable (
id BIGINT,
name STRING,
age INT,
status BOOLEAN,
PRIMARY KEY (id) NOT ENFORCED
) WITH (
'connector' = 'jdbc',
'url' = 'jdbc:mysql://localhost:3306/mydatabase',
'table-name' = 'users'
);`
```
那么想从kafka消费数据写入iotdb，请问怎么写呢？谢谢

Begin by checking the documented flink-sql-iotdb-connector dependency and the existing Flink SQL connector documentation. Confirm the artifact can be resolved and document a Kafka-to-IoTDB SQL example, including the dependency coordinates and a successful end-to-end run.
