java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.AnnotationIntrospector.findPropertyDesc

[Sudhakar Betha]

I have an existing Rest API to which when I add swagger Annotation, the swagger.json generated throws error 

javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.AnnotationIntrospector.findPropertyDescription(Lcom/fasterxml/jackson/databind/introspect/Annotated;)Ljava/lang/String;

	org.glassfish.jersey.servlet.ServletContainer.service(ServletContainer.java:221)
	org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

I am using tomcat and I have jersey2 with jackson 2.7.2 

My pom.xml is 

<dependency>
   <groupId>com.fasterxml.jackson.jaxrs</groupId>
   <artifactId>jackson-jaxrs-json-provider</artifactId>
   <version>2.7.2</version>
</dependency>

</dependency>
<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-annotations</artifactId>
   <version>2.7.2</version>
</dependency>

My web.xml is

My Api is 

@Path("hello")
@Api(value="Hello", description="Interacting with Hello resource")
public class HelloResource{

@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public String  getVersion() throws RemoteException {
    .....
    return version;
}


Why is it that Jersey2 with Jackson 2.7.2 still throws java.lang.NoSuchMethodError for 

com.fasterxml.jackson.databind.AnnotationIntrospector.findPropertyDescription

I see the doc and its available 2.3 

Can someone please help ?

Thanks,

I was able to resolve this. Looks like someother version of jackson is being loaded.

So I deleted the maven repository for jackson jars and it re-imported again this time.

So was able to loan swagger.json correctly this time.

Thanks,
