I just downloaded Eclipse and the Google Plugin to begin compiling the Google Web Toolkit from the source and building a sample application with it. However, upon installation of the plugin, I am getting this error:

From the look of the error, I’d say this might have something to do with Google actually, unless I’m missing something incredibly obvious.
Try this
Help-> Install New Software -> paht: http://dl.google.com/eclipse/plugin/4.2
did you try same link?
