Вызвано: java.lang.ClassNotFoundException: org.elasticsearch.transport.Netty3Plugin

Я использую Spring Boot 2.0.3 Release, и у меня возникли проблемы при создании экземпляра org.elasticsearch.client.Client. Мой код:

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

Этот код дает мне ошибку:
