Caused by: java.lang.ClassNotFoundException: org.elasticsearch.transport.Netty3Plugin

Question

I\'m using Spring Boot 2.0.3 Release and i have problem while instantiating org.elasticsearch.client.Client. My code:

Client client = new PreBui         


        

Answer 1

Not all dependencies are satisfied by only adding spring-boot-starter-data-elasticsearch.

It's necessary to explicitly define all remaining dependencies:

    
        org.elasticsearch.client
        transport
        ${elasticsearch.version}
    

    
        org.elasticsearch.plugin
        transport-netty4-client
        ${elasticsearch.version}
    

If you've declared a parent, most likely tag can be omitted.
