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

Project->Properties->Java Build Path, find GWT SDK in this list, click Edit.

• If Use default SDK is checked make sure the default is available. If not, click Configure SDKs... and make sure you don't have an x symbol on your SDK. If so, remove it and re-add it.

• If Use specific SDK is checked, make sure you've selected one that is available.
