cannot find symbol setObjectMapper in class Unirest

while trying to set the object mapper for Unirest using ` Unirest.setObjectMapper(new ObjectMapper() { private com.fasterxml.jackson.databind.ObjectMapper jacksonObjectMapper = new com.fasterxml.jackson.databind.ObjectMapper();

        public <T> T readValue(String value, Class<T> valueType) {
            try {
                return jacksonObjectMapper.readValue(value, valueType);
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
        }
        
        public String writeValue(Object value) {
            try {
                return jacksonObjectMapper.writeValueAsString(value);
            } catch (JsonProcessingException e) {
                throw new RuntimeException(e);
            }
        }
    });

@ryber thank you very much for your feedback, I finally have a solution, yes you were right the version I was using was well out of date.

My gradle dependencies are now: -

    // https://mvnrepository.com/artifact/com.konghq/unirest-java
compile 'com.konghq:unirest-java:3.1.04'
    compile group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.9.4'

My configuration class does this…

@Configuration
public class UnirestConfig {
    @Autowired
    private com.fasterxml.jackson.databind.ObjectMapper mapper;

    @PostConstruct
public void postConstruct() {
    Unirest.config().setObjectMapper(new ObjectMapper() {

        public String writeValue(Object value) {
            try {
                    return mapper.writeValueAsString(value);
            } catch (JsonProcessingException e) {
    	        throw new RuntimeException(e);
            }
        }
            public <T> T readValue(String value, Class<T> valueType) {
            try {
                    return mapper.readValue(value, valueType);
                } catch (Exception e) {
                    throw new RuntimeException(e);
            }
        }
     });
       }
}

My controller class can now use Unirest with Java Classes

         HttpResponse<JsonNode> createUserResponse = Unirest.post(auth0UserCreateEndpoint)
                        .header("content-type", "application/json")
                        .header("authorization", "Bearer " + token)
                        .body(newUser)     // <== this is a User class instance
                        .asJson();

Works a treat, very happy with the results.

try using a modern version. Note that we changed groupId and everything

<!-- Pull in as a traditional dependency -->
<dependency>
    <groupId>com.konghq</groupId>
    <artifactId>unirest-java</artifactId>
    <version>3.1.02</version>
</dependency>

<!-- OR as a snazzy new standalone jar with shaded dependencies -->
<dependency>
    <groupId>com.konghq</groupId>
    <artifactId>unirest-java</artifactId>
    <version>3.1.02</version>
    <classifier>standalone</classifier>
</dependency>
