Build Identifier: I20100608-0911

I have google web toolkit 2.0.4 installed.
I have selected a project of mine and then right click->properties->Google->Web Toolkit->and checked Use Google web toolkit.
The project does not have any facets or any dependencies on WTP, but it contained some jsps that were opened in an editor.

The following error occurred during selection "Use Google web toolkit':
