ProGuard + Maven with Java 7

Question

I\'m trying to make ProGuard part of our Maven build process. The problem is that the official Maven plugin is using ProGuard 4.3, which doesn\'t support Java 7. Is there any ea

I use the proguard-maven-plugin from com.github.wvengen. Note the different groupId. That way I can use the latest proguard-base artifact 5.0. Both are in Maven Central. Here's how the proguard-base portion in my pom.xml looks right now:

Parent pom.xml:

    
        
            
                com.github.wvengen
                proguard-maven-plugin
                2.0.8
                
                    
                        net.sf.proguard
                        proguard-base
                        5.0
                        runtime
                    
                
            
[...]

Here's the rest from my child pom.xml, but you probably want to modify that:

 
    
        
            com.github.wvengen
            proguard-maven-plugin
            
                
                    process-classes-with-proguard
                    process-classes
                    
                        proguard
                    
                    
                        256m
                        classes
                        
                            ${rt.jar.path}
                            ${jsse.jar.path}
                        
                        true
                        true
                        false
                        ${project.basedir}/proguard.conf
                    
                
            
        

UPDATE: For my Android projects I'm not using a dedicated Proguard plugin like proguard-maven-plugin since the android-maven-plugin handles the ProGuard obfuscation itself, and is integrated better into the build process for Android.
