Elasticsearch（6.5）高级java rest客户端按名称删除索引不起作用

我可以通过如下方式传递索引名、类型和id来删除文档-

DeleteRequest deleteRequest = new DeleteRequest(data.getIndexName(),data.getType(),data.getUniqueId());

    DeleteResponse deleteResponse = client.delete(deleteRequest);

但是，当我试图删除一个索引时，只给索引名，如下所示-根据这个

得到-

org.elasticsearch.action.ActionRequestValidationException: Validation Failed: 1: type is missing;2: id is missing;

我试过另一种方法

获取：

java.lang.NoSuchMethodError: 
at org.elasticsearch.client.IndicesClient.delete(IndicesClient.java:93) ~[elasticsearch-rest-high-level-client-6.5.4.jar:6.4.3]

我正在使用此依赖项：

<dependency>
       <groupId>org.elasticsearch.client</groupId>
       <artifactId>elasticsearch-rest-high-level-client</artifactId>
       <version>6.5.4</version>
</dependency>

这是我的pom.xml

Spring boot v2.1.2版本为elasticsearch版本定义了一个属性，如下所示

<elasticsearch.version>6.4.3</elasticsearch.version>

以及以下依赖性

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>${elasticsearch.version}</version>
</dependency>

这就是在依赖关系树中出现这种情况的原因

org.elasticsearch:elasticsearch:jar:6.4.3:compile

要强制加载elasticsearch 6.5.4，请在pom中添加以下属性，该属性将覆盖spring boot dependencies pom中定义的属性

<properties>
    <elasticsearch.version>6.5.4</elasticsearch.version>
</properties>
<dependencies>
    ...
    <dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>elasticsearch-rest-high-level-client</artifactId>
        <version>${elasticsearch.version}</version>
    </dependency>
    ...
</dependencies>

第二条路是正确的。奇怪的是，它抛出了这个错误，因为版本6.5.4已经有了delete方法。看起来没有加载的版本是正确的。检查是否有依赖项覆盖了版本。@NishantSaini我已经添加了我使用过的依赖项。它在pom.xml中为elasticsearch rest高级客户端显示了一条覆盖托管版本6.4.3的警告。这就是“删除索引”在依赖关系树中不起作用的原因吗？请检查正在使用哪个版本的elastic search org.elasticsearch。这应该是6.5.4或更高版本。@NishantSaini我添加了mvn依赖项：树不知道为什么显示6.4.3？我的pom中只有6.5.4依赖项。是的，它可以完成这项工作。谢谢
