A not complete Java client for Atlassian Stash. Currently we extend it with only what we need, but we happily apply your pull-request :D
In its simplest form you do:
StashApi api = StashClient.create("url");
Page<Project> pagedProjects = api.getProjects();
List<Project> projects = pagesProjects.values();
Each call on api results in a HTTP(s) call.
The StashClient is a direct wrapper around the Stash APIs, without any beautification' whatsoever.
Follow the code-completion of your favorite IDE, it should speak for itself :)
