If you have your SDK folder mounted as an Eclipse project you either need to remove it from your workspace or make sure the files are open and accessible.

OK,Mr.Now,I create it successful but there some new problems start. Please look at the picture 2 ,I create a liferay project,and deploy it successful.After I start the Tomcat and open the localhost:8080 webpage,while I cannot find the new portlet in the samples,the picture 3 shows the problem.
Could you help me ?Thanks!
