Tested with latest 0.31.0 release and had same issue. Tried with @frawa suggestion but I had same result. The only workaroud that worked was putting args as canonical maven properties as stated by @rhuss Until this unexpected bug gets resolved, I would suggest to update documentation (which is well written in general) with an alert linking this issue.

@KowKiller sorry, there is probably no good easy solution. You could go to use multi-modules (which then has different property names) or use profiles and two runs, but that’s tedious.

Maybe we should fix this issue ? Unfortunately, I don’t have time to code on it, but maybe someone could pick up the ideas laid out in this issue ?
