Thanks for the hint I saw that there is an ejbjar tasks that use the BCEL parser https://ant.apache.org/manual/Tasks/ejb.html
could I use this to build "normal" jar file ? BCEL seems to be what's is needed to have the job done in ant. There is a listclass.java example that list the dependencies starting from the class given in argument. I could still take this to have a list that I could use with a normal jar ant task.... Strange that BCEL is not use with the jar task in ant ...

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.
