I learn es6.1 by [https://www.elastic.co/guide/en/elasticsearch/client/java-api/6.1/java-docs-index.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/6.1/java-docs-index.html)  
but test case error.  
my build.gradle:

```
dependencies {
compile 'org.springframework.boot:spring-boot-starter-actuator'
compile 'org.elasticsearch:elasticsearch:6.1.0'
compile 'org.elasticsearch.client:transport:6.1.0'
compile 'io.springfox:springfox-swagger2:2.7.0'
compile 'io.springfox:springfox-swagger-ui:2.7.0'
compile 'org.springframework.boot:spring-boot-starter-web'
compile 'com.google.guava:guava:23.5-jre'

testCompile 'org.springframework.boot:spring-boot-starter-test'
testCompile 'junit:junit:4.12'
providedCompile 'org.projectlombok:lombok:1.16.18'
}

```

my test case

```
@Test
  public void createDoc() {
    ObjectMapper objectMapper = new ObjectMapper();
    TransportClient client = null;
    User user = new User();
    user.setAddress("beijingshi");
    user.setAge(28);
    user.setName("alvin");
    try {
      Settings settings = Settings.builder()
          .put("cluster.name", "my-application").build();
      client = new PreBuiltTransportClient(settings);
      IndexResponse indexResponse = client.prepareIndex("my_index", "user").setSource(user).get();
      System.out.println(indexResponse.getId());
      System.out.println(objectMapper.writeValueAsString(indexResponse.getResult()));
      System.out.println(objectMapper.writeValueAsString(indexResponse.getShardInfo()));
    } catch (Exception ex) {
      ex.printStackTrace();
    } finally {
      if (Objects.nonNull(client)) {
        client.close();
      }
    }

```

I had same problem. You can easily fix it by directly adding transport-netty4-client 6.1.0 in your dependencies.

`compile 'org.elasticsearch.plugin:transport-netty4-client:6.1.0'`

Looks like it's some problem in dependency tree by default it's transport-netty4-client 5.5.3 in dependencies.
