I'm using auth0-java client library to interact with auth0 v2 service, my codes compile and works fine at my development environment but when I deploy that build in another test environment it throws the following exception:

java.lang.NoSuchMethodError:com.fasterxml.jackson.databind.ObjectMapper.readerFor(Lcom/fasterxml/jackson/databind/JavaType;)Lcom/fasterxml/jackson/databind/ObjectReader;
    at com.auth0.json.mgmt.users.UsersPageDeserializer.getArrayElements(UsersPageDeserializer.java:52)

I've already gone through several stackover flow questions like this and tried by cleaning .m2/repository/com/fasterxml folder of that test environment, but cloudn't solve the no such method error here is my pom file and related codes are given below:

code

public User getUserByEmail(String email){
        UserFilter filter = new UserFilter();
        filter.withQuery(email);
        Request<UsersPage> request = mgmt.users().list(filter);
        try {
            UsersPage response = request.execute();
            for (User u:response.getItems()) {
                if (u.getEmail().equals(email)) {
                    return u;
                }
            }
        } catch (APIException exception) {
            // api error
            System.out.println("APIException:::::"+exception.getDescription());
        } catch (Auth0Exception exception) {
            // request error
             System.out.println("Auth0Exception:::::"+exception.getMessage());
        }catch(Exception ex){
            System.out.println("Other exception:::::"+ex.getMessage());
        }
        return null;
    }

pom.xml

<properties>
    <jackson.version>2.8.5</jackson.version>
  </properties>
        <dependency>
            <groupId>com.fasterxml.jackson.dataformat</groupId>
            <artifactId>jackson-dataformat-yaml</artifactId>
            <version>${jackson.version}</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>${jackson.version}</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
            <version>${jackson.version}</version>
        </dependency>
     <dependency>
        <groupId>com.auth0</groupId>
        <artifactId>auth0</artifactId>
        <version>1.0.0</version>
    </dependency>

Update I've moved those jackson dependencies into <dependencyManagement> section of my pom.xml file,

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-core</artifactId>
                <version>2.8.5</version>
            </dependency>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-databind</artifactId>
                <version>2.8.5</version>
            </dependency>
            <dependency>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-annotations</artifactId>
                <version>2.8.0</version>
            </dependency>
        </dependencies>
    </dependencyManagement>

according to maven documentation ,no matter which version of library jackson-core is requested by a dependency, version ${jackson.version} will always be used, still my codes works in local ,but in that test server the the exception remains same, even if I deploy my war file in that test server code throws the same exception.

most likely you have compiled your code against a different version of the class, than the one you are using when running it.

Please make sure that on the environment where you run the code there is no any other version of jackson-databind dependency on your classpath.
