删工程时总间断,后来从文件删除,不能导入 Some projects cannot be imported because they already exist

删工程时总中断,后来从文件删除,不能导入 Some projects cannot be imported because they already exist
原因:删除这个工程时,总是出现部分文件正在使用,无法删除,后来就把tomcat及,workspace里的工程全删了,重启myeclipse,再导入工程,则出现这个错误

解决办法:打开要导入的工程:找到与src同目录下的.project文件,打开,改变<name></name>里的工程名称,再导入即可
