I've tried to create a web installation, and the maven build is failed.
I've made a hack fix: https://github.com/llibicpep/izpack/commit/bb3d70be2b58c2c9eb99aec540732373363965ef
This hack should be completely rewritten (so I wont create a pull request). As I am a newbie in IzPack 5 - I can't do it myself. If somebody can give me some explanation how it's can be fixed in the right way - I will try to fix it.
