Jar Target

Assume a user creates a java project where there should be two outputs 
one containing the implementation and the other containing the 
interfaces. Also, assume that the compiled classes build step must be 
preceeded by a build step which generates interfaces based on the 
implementation classes.

com
   xyz
      Impl.class
      Interface.class (generated from Impl during build)

Will the jar target support the ability to filter the single compiled 
classes to produce the jar files below (please describe how one would do 
this through the user interface and java interface)?

Jar1
   com
     xyz
       Impl.class
Jar2
   com
      xyz
        Interface.class
