Apache Flink： java.lang.NoClassDefFoundError

我正在尝试遵循此示例，但是当我尝试编译它时，我遇到了此错误：

Error: Unable to initialize main class com.amazonaws.services.kinesisanalytics.aws
Caused by: java.lang.NoClassDefFoundError: org/apache/flink/streaming/api/functions/source/SourceFunction

错误是由于以下代码：

    private static DataStream<String> createSourceFromStaticConfig(StreamExecutionEnvironment env) {
        Properties inputProperties = new Properties();
        inputProperties.setProperty(ConsumerConfigConstants.AWS_REGION, region);
        inputProperties.setProperty(ConsumerConfigConstants.STREAM_INITIAL_POSITION, "LATEST");

        return env.addSource(new FlinkKinesisConsumer<>(inputStreamName, new SimpleStringSchema(), inputProperties));
    }

我想这是有问题的一行：

  return env.addSource(new FlinkKinesisConsumer<>(inputStreamName, new SimpleStringSchema(), inputProperties));

这是我的 maven 依赖项：

可能出了什么问题？任何依赖项，版本？

注意：如果我注释有问题的行，程序运行没有问题。还要注意的是，此错误也出现在某些Kafka（）样本上;我看到了amamaraws.kafka.samples.CustomMM2ReplicationPolicy类的相同错误。aws-kafka
