Я пытаюсь следовать этому примеру , но когда я пытаюсь его скомпилировать, у меня появляется эта ошибка:
Error: Unable to initialize main class com.amazonaws.services.kinesisanalytics.aws
Caused by: java.lang.NoClassDefFoundError: org/apache/flink/streaming/api/functions/source/SourceFunction
Ошибка из-за этого кода:
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));
}
И я полагаю, это проблемная строка:
return env.addSource(new FlinkKinesisConsumer<>(inputStreamName, new SimpleStringSchema(), inputProperties));
Это мои maven зависимости:
Что может быть не так? какие-нибудь зависимости, версия?
Примечание. Если я прокомментирую проблемную строку, программа запустится без проблем.
