Hi, If you navigate to Project Properties -> Google -> Web Application, do you have the option "Launch and deploy from this directory" checked? If so, when you switched SDKs on your project, the Google Plugin for Eclipse should have copied over the new libraries from the SDK over to your war/WEB-INF/lib directory.
Have you manually copied/modified/removed any of the App Engine-related libraries in the war/WEB-INF/lib folder? If so, then the Google Plugin for Eclipse will not overwrite those changes on an SDK switch. What will happen is that when switching SDKs, a warning will appear in the problems view, indicating that there is a mismatch between the SDK jars and those in your war/WEB-INF/lib folder. By selecting the warning and hitting CTRL-1, you'll be given the option to synchronize the jars in the new SDK with the jars in war/WEB-INF/lib.
