SpringBoot專案引入Elasticsearch時啟動失敗

Spring BootElasticsearch

1、前情提要：

https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/installation.html

以上是Elasticsearch對接Java的官方文件（pom依賴部分）

SpringBoot專案引入Elasticsearch時啟動失敗

我本地Windows安裝的Elasticsearch也是8.15.3版本

2、啟動報錯

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    co.elastic.clients.transport.rest_client.SafeResponseConsumer.<clinit>(SafeResponseConsumer.java:52)

The following method did not exist:

    org.elasticsearch.client.RequestOptions$Builder.setHttpAsyncResponseConsumerFactory(Lorg/elasticsearch/client/HttpAsyncResponseConsumerFactory;)Lorg/elasticsearch/client/RequestOptions$Builder;

The method's class, org.elasticsearch.client.RequestOptions$Builder, is available from the following locations:

    jar:file:/C:/repository/java/org/elasticsearch/client/elasticsearch-rest-client/6.4.3/elasticsearch-rest-client-6.4.3.jar!/org/elasticsearch/client/RequestOptions$Builder.class

It was loaded from the following location:

    file:/C:/repository/java/org/elasticsearch/client/elasticsearch-rest-client/6.4.3/elasticsearch-rest-client-6.4.3.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.elasticsearch.client.RequestOptions$Builder

報錯翻譯：大意是指正在呼叫一個不存在的method，這個method對應的class在我的本地maven倉庫的xxx路徑，並提到了elasticsearch-rest-client的版本，給出的建議是糾正該client的唯一性&相容性……

我Google了一下報錯內容，在Elasticsearch官網中找到了一個類似的issue，官方給出的回答是elasticsearch-rest-client版本不對，但是那個issue最後並未被髮起者確認解決問題，而是在一段時間後自動關閉了。

3、依賴分析

SpringBoot專案引入Elasticsearch時啟動失敗

發現官方推薦的依賴中整合的elasticsearch-rest-client版本是6.4.3而非8.15.3

因此嘗試手動新增elasticsearch-rest-client8.15.3版本的依賴

        <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-client</artifactId>
            <version>8.15.3</version>
        </dependency>

再次啟動專案，啟動成功。

起初我以為是阿里映象中上傳的elasticsearch-java依賴有誤，在除錯過程中，我嘗試把maven的settings.xml檔案中的阿里映象替換成Apache倉庫，發現仍然存在該問題，因此可以確定應該是官方製作依賴時留下的bug？
