The <depend> task almost does what you want I think, but doesn't expose a Selector unfortunately. But it looks like it has the code to do what you want, with an external dependency to a .class file parser probably though. (even GenJar had plans to use BCEL for that, but that probably never materialized). Once you have that depend-based selector, you can use <jar> almost like you did <genjar> IMHO. FWIW.
