#get_dependencies_of_this_gem(name_of_the_gem = @name_of_this_gem, is_local = true) ⇒ Object Also known as: get_deps

#

get_dependencies_of_this_gem

The second argument to this method tells us whether we should work in a remote way or in a local way. If true then we will assume that all gems are local dependencies.
