java.lang.NoSuchMethodError: org.elasticsearch.action.support.master.AcknowledgedResponse

参考官方教程

<dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-high-level-client</artifactId>
            <version>7.2.0</version>
</dependency>
package com.example.restclient;

import org.apache.http.HttpHost;
import org.elasticsearch.action.admin.indices.delete.DeleteIndexRequest;
import org.elasticsearch.action.support.master.AcknowledgedResponse;
import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestClient;
import org.elasticsearch.client.RestHighLevelClient;
import java.io.IOException;


public class DeleteIndex {
    static RestHighLevelClient client = new RestHighLevelClient(
            RestClient.builder(
                    new HttpHost("localhost", 9200, "http")));

    public static void main(String[] agrs) throws IOException {
        // 1、创建请求参数
        DeleteIndexRequest request = new DeleteIndexRequest("test");
        // 2. 执行删除操作
        AcknowledgedResponse deleteIndexResponse = client.indices().delete(request, RequestOptions.DEFAULT);
        // 3、处理响应
        boolean acknowledged = deleteIndexResponse.isAcknowledged();
        System.out.println("acknowledged = " + acknowledged);
        //4.关闭RestHighLevelClient
        client.close();

    }
}

报错,找不到方法

Exception in thread "main" java.lang.NoSuchMethodError: org.elasticsearch.action.support.master.AcknowledgedResponse.fromXContent(Lorg/elasticsearch/common/xcontent/XContentParser;)Lorg/elasticsearch/action/support/master/AcknowledgedResponse;
	at org.elasticsearch.client.IndicesClient.delete(IndicesClient.java:97)
	at com.example.restclient.DeleteIndex.main(DeleteIndex.java:26)

国外用户也遇到类似的错误 https://stackoverflow.com/questions/53755092/i-got-a-java-lang-nosuchmethoderror-when-using-deleteindexrequest

解决办法,

增加一个依赖即可

        <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>7.2.0</version>
        </dependency>

看来Elasticsearch 7.x的官方文档坑还是很多的
