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:

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

    <dependency>
        <groupId>org.elasticsearch.plugin</groupId>
        <artifactId>transport-netty4-client</artifactId>
        <version>${elasticsearch.version}</version>
    </dependency>

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

Answer 2

<dependency> 
    <groupId>org.elasticsearch.client</groupId> 
    <artifactId>transport</artifactId> 
</dependency>

This is resolved for me.
