完整报错:

依赖问题:

查看是否同时含有

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka-clients</artifactId>
    <version>3.0.0</version>
</dependency>
<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-connector-kafka</artifactId>
    <version>${flink.version}</version>
</dependency>

版本依赖问题,删除kafka-clients这个有依赖即可,只保留

<dependency>
    <groupId>org.apache.flink</groupId>
    <artifactId>flink-connector-kafka</artifactId>
    <version>${flink.version}</version>
</dependency>

或新建一个项目导入以下依赖(注意版本问题,修改为自己的版本):
