Getting root cause java.lang.AbstractMethodError while using Jersey ContainerRequestFilter

Question

INFO: Server startup in 6705 ms
Nov 29, 2013 6:17:38 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [JerseyServlet] in         


        

Answer 1

I needed a more specific answer to the problem so I added the following plugin to maven:

  org.apache.maven.plugins
  maven-enforcer-plugin
  3.0.0-M3
  
    
      enforce
      
        
          
        
      
      
        enforce
      
    
  

The above showed me all the dependency conflicts so I managed to resolved more than the aforementioned problem and keep my dependency tree tidy.

The plugin runs when calling:

mvn clean install

And shows you a warning as follows:

[WARNING] 
Dependency convergence error for com.fasterxml.jackson.core:jackson-core:2.8.10 paths to dependency are:
+-com.omilia:partners:5.4.0-RC-3
  +-org.glassfish.jersey.media:jersey-media-json-jackson:2.27
    +-com.fasterxml.jackson.module:jackson-module-jaxb-annotations:2.8.10
      +-com.fasterxml.jackson.core:jackson-core:2.8.10
and
+-com.omilia:partners:5.4.0-RC-3
  +-com.fasterxml.jackson.core:jackson-databind:2.9.6
    +-com.fasterxml.jackson.core:jackson-core:2.9.6

Subsequently, you can exclude the specific package, when referencing your dependency in your pom:

  com.fasterxml.jackson.core
  jackson-core
