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.
This is all explained here: https://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#gettingstarted-framework-spring-boot-dependency-versions
Basically, Spring Boot is managing your dependencies, and it's forcing an older version of the Elasticsearch client. You need to force it back to the version Hibernate Search expects (a newer version, 7.16.x).
And just to clarify, this has nothing to do with the Elasticsearch server version that I've seen mentioned in other answers. This is strictly about your client.
