The project XXX does not have any GWT SDKs on its build path

Question

Sometimes, when I start Eclipse (Java EE IDE for Web Developers, Indigo SR 1) on my MacOSX Lion, my GWT (2.4.0) project initially fails to compile<

Answer 1

I believe the problem was occurring because Eclipse had some stale settings about available/linked GWTs.

Therefore, building on the answer by Chris Cashwell, I recommend the following:

1. Remove all GWTs from your build path. (You might have more than one GWT on your build path.)
2. Remove all GWTs linked in Eclipse in Project>Properties>Google>Web Toolkit>Configure SDKs, .
3. Add only the latest GWT, and make it default.

EDIT: Sometimes, I still need to do a Project > Clean, but this is rare now.
