From what I read on other forums, Google deletes old plugins after 2 releases go by. No one in my group thought to archive the GWT Eclipse 3.5 plugin. Now the GWT Eclipse plugin is gone, and all attempts to use a later version of Eclipse have failed. The failures are due to tight coupling between JBoss ESB 4.7 and their customized "JBoss developer studio".
It would seem a small matter for Google to fix all the broken links on their site by putting the files back, and I'm trying to find a way to ask them to do that.
In the mean time, did anyone out there manage to squirrel away a copy of the plugin? Thanks!
