Item no error also reported this project needs to migrate WTP metadata wrong

Overall, the project error occurred: This item needs to migrate WTP metadata resolved: Right-click on the project and select "Validate", that is, validate can be resolved, but the location is different.

The simple solution is to right-click on the project and select Validate, and the error disappears after the validate is done.

But my notebook myeclipse is no Validate option, later found that in the project right-click option MyEclipse There is a run Validate, after clicking it, run an error disappears, good.
