Question

我正在尝试从github（https://github.com/kafka-dev/kafka/tree/master/examples/src/main/java/kafka/examples）的kafka示例中编译jar项目

设置环境和所有组件（Kafka 2.11-1.1.0和zookeeper，创建一个主题并更改所有属性的东西）之后，该项目实际上在Eclipse Eclipse中使用Maven 3.3.9取得了成功。尝试java -jar *******。jar我收到以下错误。

    Exception in thread "main" java.lang.NoClassDefFoundError: kafka/utils/ShutdownableThread

这是TestConsumer.java

package org.apache.apex.examples.kafka.kafka2hdfs;

public class TestConsumer {
    public static void main(String[] args) {

        Consumer consumerThread = new Consumer(KafkaProperties.TOPIC);
        consumerThread.start();
        System.out.println("ok");
    }
}

编译jar项目Maven Eclipse时出错
