GWT 2 upgrade almost painless

I took the plunge and upgraded my Google Eclipse plugin and SDKs to GWT 2 using the normal Eclipse update mechanism. The new development mode threw me for a bit of a loop, but that’s the only problem so far. The GWT 2 docs say that the browser will automatically prompt you to download the Google Web Toolkit Developer plugin, but that wasn’t happening for my existing GWT project, only new ones.

The solution was simply to delete the generated app directories under the war folder, and clean and rebuild the project. Then I was prompted to download the plugin as expected, and the browser makes the connection to Eclipse so I can view the GWT logs.

So far so good. I’m anxious to try out the new UIBinder templating and hopefully simplify page layout issues…
