Help with new Roo Project

[lucasite]

Hi,
Help - I cant build my project.
Its really wierd. Last night I created a new spring roo project, followed a tutorial on creating an entity and some fields. I ran gwt setup. And everything worked fine. I could run the project and play with the scaffold app in a browser.

This morning I open eclipse, and I have a red x symbol on my project.
If I clean the project, it goes away temporarily and comes back once the project has finished building.

There's no output in the console tab to show any errors.
The red x symbol only appears at the project level, it doesnt point to any specific file. And to be honest, I havent changed any files yet.

Ive tried closing/opening sts eclipse.
Ive tried closing/reopening the project.

Im scratching my head, I dont know what else to do.

Can anyone suggest how I can trace what the problem is?

I discovered if I opened the Error Log window, there was a more accurate error message there.
It seems the project drops the reference to GWT SDK library.
I had to add it again by simply right clicking on project, selecting google, web settings. and clicking ok on the dialog box.

Take a look in Eclipse's "Problems" view.
Window -> Show View -> Problems
