Causé par: Java.lang.ClassNotFoundException: org.elasticsearch.transport.Netty3Plugin

J'utilise la version Spring Boot 2.0.3 et j'ai un problème lors de l'instanciation de org.elasticsearch.client.Client. Mon code:

Client client = new PreBuiltTransportClient(Settings.builder()
                .put("cluster.name", clustername)
                .build())
                .addTransportAddress(
new InetSocketTransportAddress(InetAddress.getByName(Host), port)
);

Ce code me donne l'erreur:

Toutes les dépendances ne sont pas satisfaites en ajoutant uniquement spring-boot-starter-data-elasticsearch.

Il est nécessaire de définir explicitement toutes les dépendances restantes:

    <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>

Si vous avez déclaré un parent, probablement <version> la balise peut être omise.

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

C'est résolu pour moi.
