1) Gem names with ":" will not work on Windows, is not safe.

2) RubyGems cannot install gems across multiple repositories (so if
your maven wrapper is in another server it will not find it)

3) Last but not least: let's not turn RubyGems "dependencies" into
"anything this gem depend on".

RubyGems dependencies *must be* a gem.
