Original asmack repository has wrong configs,
I doubt that this is the case. I've use the build script to create the most recents 4.0.3 aSmack snapshots.
Note that if you think you need to build aSmack from source, then you are have most likely a flaw in your design. Smack (and this includes aSmack) is designed to be easily extensible in the place where it's possible to be extended. If you need to extend it somewhere else, then you will likely produce non-standard confrom XMPP stanzas/elements.
