java.lang.NoSuchMethodError: com.fasterxml.jackson.core.JsonFactory.requiresPropertyOrdering()Z

I have project which locally works fine but when I deploy war to server and try to execute Rest method, I get: 

java.lang.NoSuchMethodError: com.fasterxml.jackson.core.JsonFactory.requiresPropertyOrdering()Z
    com.fasterxml.jackson.databind.ObjectMapper.<init>(ObjectMapper.java:474)
    com.fasterxml.jackson.databind.ObjectMapper.<init>(ObjectMapper.java:393)
    com.fasterxml.jackson.jaxrs.json.JsonMapperConfigurator.getDefaultMapper(JsonMapperConfigurator.java:44)
    com.fasterxml.jackson.jaxrs.base.ProviderBase.locateMapper(ProviderBase.java:866)

I know that it is related with overlapping jars but could not find a solution. When I use JHades, I get messages related with Json or Jackson:

file:/C:/Users/justas/.m2/repository/com/google/http-client/google-http-client-jackson2/1.20.0/google-http-client-jackson2-1.20.0.jar overlaps with 
file:/C:/Users/justas/.m2/repository/ppp/ppp/1.0/ppp-1.0.jar - total overlapping classes: 5 - same classloader ! This is an ERROR!

file:/C:/Users/justas/.m2/repository/com/fasterxml/jackson/core/jackson-core/2.5.4/jackson-core-2.5.4.jar overlaps with 
file:/C:/Users/justas/.m2/repository/ppp/ppp/1.0/ppp-1.0.jar - total overlapping classes: 79 - same classloader ! This is an ERROR!

Pom.xml fragment related with Json or Jackson:

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-jackson</artifactId>
    <version>2.22.</version>
</dependency>

I was trying to remove or replace jars but it does not work. How to solve this problem?

Added and worked like a charm:

<dependency>
  <groupId>com.owlike</groupId>
  <artifactId>genson</artifactId>
  <version>1.4</version>
</dependency>
