I’m not sure. I haven’t seen that error before and am not sure which plugin contributed it (I know MyEclipse didn’t, but I mean other than WTP or Maven).
If you switch to the Navigator view, you should be able to see all the dot files in the project that define the project’s metadata. The MyEclipse ones usually have “my” in the name. That might help you figure out which ones it’s referring to.
I recently upgraded to 5.5.. I have an existing web project that does not use maven, but when I do a clean and rebuild I get the error “This project needs to migrate WTP metadata”. The error shows up about the same time the Facelets Validator phase is indicated.
I choose the “migrate WTP metadata” quick fix, and nothing happens.
How can I get rid of the error message or disable the Facelets Validation?
