我java.lang.NoClassDefFoundError:在尝试建立elasticsearch客户时得到了。我知道这主要是因为JAR版本不匹配/如果JAR缺少任何内容，但我已经搜索了很长时间，但我不知道我缺少什么。

JAR 列表。

  1. elasticsearch-6.1.0.jar
  2. transport-7.3.1.jar

代码 ：

if(client==null){
    System.out.println("called  inside configure client ->> ");
    InetAddress address = InetAddress.getByName("localhost");

    int port = 9200;

    client =  new PreBuiltTransportClient(Settings.EMPTY).addTransportAddress(new TransportAddress(address,port)); 

    String[] indices = client.admin().indices().getIndex(new GetIndexRequest()).actionGet().getIndices();
    for (String s : indices) {
        System.out.println("index  ->> " + s);
    }
}

堆栈跟踪 ：
