Maven - create jar manifest with two classpath prefixes

I am writing a pom file of my project, but I am facing a problem in the classpath entries. In my pom I have set

plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>
                <classpathPrefix>lib/</classpathPrefix>
            </manifest>
        </archive>
    </configuration>
/plugin>

      

        
        
        
      

    

but with this conf in the generated librairies manifests it is assumed to be in lib /. In fact, they are all located either in .... /lib/public/or..../lib/private/. Is it possible to distinguish the location of librairies in the pom file to have a different prefix in the generated manifest?

thank
