Tomcat in Eclipse cannot publish Web projects by using Add and remove

This time, after the last launch of the Tomcat ClassNotFound in Eclipse, a new problem has been encountered. Right-click Tomcat to use Add and remove to publish the Web project to Tomcat, start the Tomcat container error, and so on. Then check the publish directory and discover that the published Web project D:\WorkSpace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps not found in the default publishing directory. That is, publishing failed.

Started thinking it was Tomcat, and then deleted Tomcat re-add, then publish Web project discovery is not yet. Click Open Tomcat to view the published Web project, and find the published Web project a little strange. In the past, you can also click Open Web Project to view other projects that depend on the Web project, but now find that this Web project has no subdirectories, that is, it does not see the artifacts it relies on. Suspicion is dependent on the problem, suddenly think of this morning because of the project of the error, so the project was deleted, and then re-introduced from SVN, so into the deployment assembly the original project to rely on and re-add again. After apply, it is found that the published project is OK.
