安装以前版本的GPE？

Question

I want to roll back my Google Plugin for Eclipse to a previous version. How can I accomplish that?

Answer 1

Use Help>About>Installation Details>Installation History to see your past list of installed configurations. You should be able to select one and revert to that configuration.

EDIT : update from comments

While eclipse keeps around the past configurations it may need to go to p2 repositories on the internet to download the older artifacts (and that can trip up some configuration reverts).

Answer 2

Unless you have a copy of the older version, you can't roll back. You can definitely get old versions of GWT, but they don't keep around old versions of GPE.
