Method does not exist: org.elasticsearch.client.RequestOptions$Builder.setRequestConfig(Lorg/apache/-CodePudding

I am creating Hibernate Search 6 application with Spring Boot 2.3.4

I am facing this error while I try to build my application -

Description:

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

   org.hibernate.search.backend.elasticsearch.client.impl.ElasticsearchClientImpl.setPerRequestSocketTimeout(ElasticsearchClientImpl.java:198)

The following method did not exist:


org.elasticsearch.client.RequestOptions$Builder.setRequestConfig(Lorg/apache/http/client/config/RequestConfig;)Lorg/elasticsearch/client/RequestOptions$Builder;

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

jar:file:/C:/Users/pranali.rasal/.m2/repository/org/elasticsearch/client/elasticsearch-rest-client/7.6.2/elasticsearch-rest-client-7.6.2.jar!/org/elasticsearch/client/RequestOptions$Builder.class

The class hierarchy was loaded from the following locations:

org.elasticsearch.client.RequestOptions.Builder: 
file:/C:/Users/pranali.rasal/.m2/repository/org/elasticsearch/client/elasticsearch-rest-client/7.6.2/elasticsearch-rest-client-7.6.2.jar


Action:

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

Following are the dependencies that i have added -

        <dependency>
            <groupId>org.hibernate.search</groupId>
            <artifactId>hibernate-search-mapper-orm</artifactId>
            <version>6.1.5.Final</version>
        </dependency>

        <dependency>
            <groupId>org.hibernate.search</groupId>
            <artifactId>hibernate-search-backend-elasticsearch</artifactId>
            <version>6.1.5.Final</version>
        </dependency>

Let me know if I missing something.

CodePudding user response：

This is probably due to incompatible version of the elasticsearch dependency. From https://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#getting-started-compatibility it seems you need 7.10 or 7.16 but you have 7.6 dependency. Also check server version to be sure.

CodePudding user response：

hibernate-search-backend-elasticsearch

is internally dependent on elasticsearch-rest-client-7.6.2.jar

And the method

org.elasticsearch.client.RequestOptions$Builder.setRequestConfig(Lorg/apache/http/client/config/RequestConfig;)Lorg/elasticsearch/client/RequestOptions$Builder;

it is trying to find is in later versions of low level client.

Temporary solution will be to exclude 7.6.2 and include latest version of elasticsearch-rest-client-7.6.2.jar -

    <dependency>
        <groupId>org.hibernate.search</groupId>
        <artifactId>hibernate-search-backend-elasticsearch</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.elasticsearch.client</groupId>
                <artifactId>elasticsearch-rest-client</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

and including,

       <dependency>
            <groupId>org.elasticsearch.client</groupId>
            <artifactId>elasticsearch-rest-client</artifactId>
            <version>7.10.0</version>
        </dependency>

Since this is a temporary, I am not sure if this is reliable. Please let me know in case there is a better solution.
