Exception in thread "main" java.lang.NoSuchMethodError: com.fasterxml.jackson.core.JsonFactory.requiresPropertyOrdering()Z

I need to convert json to pojo. I Decided to use jackson and have added jackson-core-2.2.0.jar, jackson-databind-2.4.4.jar and jackson-annotations-2.1.2.jar to my project's classpath

I created following Main class:

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.List;
import com.fasterxml.jackson.core.JsonGenerationException;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonMappingException;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.core.JsonGenerationException;
import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.JsonMappingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.DeserializationFeature;

public class Json {
private static String SRC= "";

  public static void main(String[] args) {

      AwardList awardList = null;
      ObjectMapper mapper = new ObjectMapper();

      try{
          awardList = (AwardList) mapper.readValue(new URL(SRC), AwardList.class);
      }catch (JsonGenerationException e){
          e.printStackTrace();
       } catch (JsonMappingException e){
          e.printStackTrace();
       } catch (IOException e){
          e.printStackTrace();
       }
       System.out.println(awardList);

  }
}

And following AwardList class:

public class AwardList {

    private Flights[] flights;
    private String[] connections;

    private SaverEconomy saverEconomy;
    private StandartEconomy standartEconomy;
    private SaverBusiness saverBusiness;
    private StandartFirst standartFirst;
    private SaverFirst saverFirst;


    public Flights[] getFlights() {
        return flights;
    }

    public void setFlights(Flights[] flights) {
        this.flights = flights;
    }

    public SaverEconomy getSaverEconomy() {
        return saverEconomy;
    }

    public void setSaverEconomy(SaverEconomy saverEconomy) {
        this.saverEconomy = saverEconomy;
    }

    public StandartEconomy getStandartEconomy() {
        return standartEconomy;
    }

    public void setStandartEconomy(StandartEconomy standartEconomy) {
        this.standartEconomy = standartEconomy;
    }

    public SaverBusiness getSaverBusiness() {
        return saverBusiness;
    }

    public void setSaverBusiness(SaverBusiness saverBusiness) {
        this.saverBusiness = saverBusiness;
    }

    public StandartFirst getStandartFirst() {
        return standartFirst;
    }

    public void setStandartFirst(StandartFirst standartFirst) {
        this.standartFirst = standartFirst;
    }

    public SaverFirst getSaverFirst() {
        return saverFirst;
    }

    public void setSaverFirst(SaverFirst saverFirst) {
        this.saverFirst = saverFirst;
    }

    public String[] getConnections() {
        return connections;
    }

    public void setConnections(String[] connections) {
        this.connections = connections;
    }
}

I want to convert json to pojo and save it in the database. I keep getting following error:

Exception in thread "main" java.lang.NoSuchMethodError: com.fasterxml.jackson.core.JsonFactory.requiresPropertyOrdering()Z
  at com.fasterxml.jackson.databind.ObjectMapper.<init>(ObjectMapper.java:457)
  at com.fasterxml.jackson.databind.ObjectMapper.<init>(ObjectMapper.java:379)
  at Json.main(Json.java:72)

I was getting the exactly same issue. I was using Maven for dependency management and had added dependency for jackson-databind module only like this

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>${jackson.version}</version>
</dependency>

and then I resolved it by doing this.. I added its transitive dependencies explicitly with the same jackson.version mentioned for each of them in the pom.xml file, as guided here

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>${jackson.version}</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>${jackson.version}</version>
</dependency>
