I\'ve been developing a java application using git as source code repository. I\'d like to share the project with other java developers and hg seems to be most used by them.
You may want to look at the http://hg-git.github.com/ utility: a Git plugin for Mercurial
This plugin is originally developped by the guys of GitHub, and allows the convert from git<->mercurial losslessly. In theory, you could even be able to clone the hg repository.
