      NEWER than swap file!

(1) Another program may be editing the same file.  If this is the case,
    be careful not to end up with two different instances of the same
    file when making changes.  Quit, or continue with caution.
(2) An edit session for this file crashed.
    If you did this already, delete the swap file ".server.xml.swp"
    to avoid this message.

Swap file ".server.xml.swp" already exists!

[O]pen Read-Only, (E)dit anyway, (R)ecover, (D)elete it, (Q)uit, (A)bort:

解决方案：ls -a 查看隐藏文件，在linux系统中  隐藏文件以点开头，如果发现类型 .server.xml.swp  的文件！直接删除就可以了
