This is used for gem dependency file support.

Example:

set = Gem::Resolver::GitSet.new
set.add_git_gem 'rake', 'git://example/rake.git', tag: 'rake-10.1.0'

    #add_git_spec(name, version, repository, reference, submodules)  
  

  

    This method is for internal use only.
  



  

    

Adds and returns a GitSpecification with the given name and version which came from a repository at the given reference.  If submodules is true they are checked out along with the repository.



This fills in the prefetch information as enough information about the gem is present in the arguments.
