GenJar replacement or upgrade?

Question

"GenJar is a specialized Ant task that builds jar files based on class dependencies, not just the contents of a directory" ( http://genjar.sourceforge.net/ )

This is really useful, but the project seems to be inactive since "2003-03-06 released GenJar 1.0.2".

Is there a new tool we should use now?

thanks

Answer 1

genjar2 seems like an “official” replacement: http://code.google.com/p/genjar2/

Answer 2

What about maven http://maven.apache.org/ ?
