Indeed, those reference didn't make it over to git.
I think the best way to deal with the situation is create a new maven branch out of the master branch and then commiting the .pom files from the old maven branch into it.
Besides, I plan to convert all non-master branches of the openfire git to tags prefixed with "attic/" as those branches shouldn't be used because most of them don't have a shared parent commit with the master branch. So please simply ignore any non-master branch for now and more importantly, don't commit against them.
