According to this post: https://groups.google.com/forum/?fromgroups#!topic/kivy-users/n7c3thksnzg, it is possible to use Eclipse as an IDE for Kivy through PyDev. However, I
I think it's just pointing that:
The PATH, GST_PLUGIN_PATH, GST_REGISTRY environment variables must be set (which you can actually do on the command line and then start up eclipse from that command line, or set in the interpreter configuration in the environment tab): http://pydev.org/manual_101_interpreter.html.
Kivy must be added to the PYTHONPATH somehow. If you want, you can add it only to a project (as pointed in the post -- see: http://pydev.org/manual_101_project_conf2.html) or to the actual interpreter configuration if more projects will share that: http://pydev.org/manual_101_interpreter.html.
