Elasticsearch(6.5) HIgh level java rest client Delete an index by name is not working

Question

I can delete a document by passing the index name , type and id like this-

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

    DeleteResponse deleteResponse = client.delete(deleteRequest);

But when I am trying to delete an index by giving the index name only like below- (According to this document)

DeleteRequest deleteRequest = new DeleteRequest(allData.getIndexName());

    DeleteResponse deleteResponse = client.delete(deleteRequest);

getting-

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

I have tried another way like this (reference)

DeleteIndexRequest request = new DeleteIndexRequest(allData.getIndexName());
    AcknowledgedResponse deleteIndexResponse = client.indices().delete(request, RequestOptions.DEFAULT);

getting:

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

I am using this dependency:

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

The second way is the right one. Weird it throws that error, though, as version 6.5.4 did have the delete method already. — Val

Seems like correct version in not loading. Check if some some dependency is overriding the version. — Nishant

@NishantSaini I have added the dependency above which I have used. And its showing one warning-"Overriding managed version 6.4.3 for elasticsearch-rest-high-level-client" in pom.xml. Is this the reason why delete index is not working — Bran

In the dependency tree check what version of elastic search (org.elasticsearch) is being used. This should be 6.5.4 or above. — Nishant

@NishantSaini I have added the mvn dependency:tree don't know why it is showing 6.4.3? I have only the 6.5.4 dependency in my pom.xml — Bran

Spring-boot v2.1.2 release has a property defined for elasticsearch version as

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

and the following dependecy

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

This is the reason for this in dependency tree

org.elasticsearch:elasticsearch:jar:6.4.3:compile

To force load elasticsearch 6.5.4 add the following property to your pom which will override the property defined in spring-boot-dependencies pom

<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>
