So here I am figuring I’d take a look at this SDK and what I can do with it. Followed your Wiki for installing the SDK, I already had JAVA and eclipse so that was done, now step 11 states Mark the checkbox for Graphical Editing Framework 3.3.0 not the "SDK" version.
UPDATE: I see to have found out that the Graphic Editing framework is already installed and enabled, probably from another plugin as I never did it, the problem I have now is then when I try to install the BUG SDK I was missing Plug-in Development Environment so after installing that it seems to work. Figure I would let you know so others who might have this problem can try to fix it themselves.
Thanks for the suggestion! Yes we probably need a separate HOWTO for installing the SDK in an existing Eclipse instance, rather than assuming a clean slate.
