About Myelipse introduction of web projects

I created a new web project wants to come before the introduction of web project , point inport-general-existing projects into workspace and then

Select the current workspace directory , but search out the projects are gray and can not be introduced , giving the error message is Some projects cannot be

imported because they already exist in the workspace Is this what's causing it ? Solution , what is it ? waiting for experts to answer ! ! !
------ Solution ---------------------------------------- ----

copying files directly related to the new project workspace under the appropriate folder , and then right-click the project name myeclipse refresh on it
------ For reference only ---------------------------------------
to determine this web project there webroot , etc., prior to the workspace are deleted ~

troublesome thing clear , you said this means that this is a new web project it or previous project? "Workspace in the previous" What does it mean something ?

good projects to add deleted , plus another when Some projects cannot be imported because they already exist in the workspace. Then do not hook the copy check box , the point right refresh.
