创建RestHighLevelClient bean时出现NoClassDefFoundError错误

我在SpringBoot应用程序中创建HighEndRestClient bean时遇到错误 . 我已经完成了一个测试'app'，我检查了我可以实例化我想要的对象，然后拨打我想要的电话，现在我正在制作新的应用程序 .

我在pom中有这些依赖项

<dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>elasticsearch-rest-client</artifactId>
        <version>5.6.3</version>
    </dependency>

    <dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>elasticsearch-rest-high-level-client</artifactId>
        <version>5.6.3</version>
    </dependency>

我已经在配置类中编写了这个非常基本的代码，但是这个代码没有做太多

@Configuration
@PropertySource(value = "classpath:application.properties")
@EnableElasticsearchRepositories(basePackages = "com.indexbuilder.es.repo")
public class ElasticsearchConfiguration {
    @Value("${elasticsearch.host}")
    private String EsHost;

    @Value("${elasticsearch.port}")
    private int EsPort;

    @Value("${elasticsearch.clustername}")
    private String EsClusterName;


    @Bean
    public RestClientBuilder coreBuilder() throws Exception {
        RestClientBuilder builder = RestClient.builder(new HttpHost("localhost", 9200, "http"));
        builder.setMaxRetryTimeoutMillis(10000);

        builder.setFailureListener(new RestClient.FailureListener() {
            @Override
            public void onFailure(HttpHost host) {
                System.out.println("FAILURE !!!! FailureListener HAS WOKEN UP!!!! CREATYE A FAILURE LISTENER BEAN" );
            }
        });

        return builder;
      }

    @Bean
    public RestClient restLowLevelClient() throws Exception{
        RestClient restClient = coreBuilder().build();
        return restClient;
    }

就我所见，这个工作正常（我还没有做太多...）

当我添加这个（最初我传入RestClient bean但现在我暂时创建一个本地对象以获得更清晰）

@Bean
    public RestHighLevelClient restHighLevelClient() throws Exception{
        RestClient restClient = coreBuilder().build();
        RestHighLevelClient client = new RestHighLevelClient(restClient);
        return client;
    }

我得到这个java.lang.NoClassDefFoundError错误

谁能指出我正确的方向？
