[FIXED] This project needs to migrate WTP metadata

After I checkout code from SVN repository, some of my Eclipse's projects alert this error

"This project needs to migrate WTP metadata"

and it's no provide clue for solve them.

I found this thread Eclipse error: This project needs to migrate WTP metadata

There's a way to solve this error almost bottom of the page.

Just right-click at alerting project and click "Validate"

Then the problem must be solved
