How do you replace the class of a Maven dependency?

Question

There is a class in a maven dependency that is incompatible with Java 8.

How do you properly fix that problem?

Right now I\'m doing the following:

Answer 1

Here is a detailed guide describing what I did exactly:

1. Create new Maven project in Eclipse

2. Configure Maven settings of new project (Important: Use the same group and artifact ID and only change the version number)

   
       4.0.0
   
       com.sun.xml.wss
       xws-security
       3.0-java8-fix
   
       
           UTF-8
           1.8
       
   
   

3. Add dependency of bugged JAR

   
       
           com.sun.xml.wss
           xws-security
           3.0
           
               
                 xmldsig
                 javax.xml.crypto
               
               
                 activation
                 javax.activation
               
           
       
      
   

4. Create Java file in the same package of class that needs to be fixed

   package com.sun.xml.wss.impl.apachecrypto;
   
   public class EncryptionProcessor {
       // The FIX goes here
   }
   

5. Add Maven shade build plug in to handle creation of patched JAR file (this is not the only plug in to handle this kind of task - e.g. dependency:unpack)

   
       
           
           
               org.apache.maven.plugins
               maven-shade-plugin
               2.1
               
                   
                       package
                       
                           shade
                       
                       
                           
                               
                                   com.sun.xml.wss:xws-security:3.0
                                   
                                       **/*.class
                                       **/*.xml
                                   
                                   
                                       
                               com/sun/xml/wss/impl/apachecrypto/EncryptionProcessor.class
                                       
                                   
                               
                           
                       
                   
               
           
       
   
   

6. Include patched JAR in other projects as necessary (Note: If you experience ClassNotFoundExceptions or similar errors do this: Right-click on the project -> Properties -> Maven -> "Resolve dependencies from Workspace projects":false)

In case you are not familiar with Maven. Here is the complete pom.xml: http://pastebucket.com/88444
