网上找了两种解决办法

1.修改项目的发布地址:

原文:

I was getting the annoying error in Eclipse with Tomcat where it
didn’t think it could publish an application since some files were
locked, when they were locked by the javaw.exe process that eclipse.exe
started. The fix for me was to not have “Use Tomcat installation”
selected in my server configuration. When I switched back to the default
of “Use workspace metadata”, the error stopped happening.

2.clean

原文:

 I performed a "clean" operation on the Tomcat server instance and
the problem just went away. It's being doing fine since that. I'll let
you know if I see this issue again.

我使用这种方法时，问题刚开始消失了，但过了一阵又是老样子。

 

我突然想到同一个eclipse下的别的项目使用的时候没有出现这个问题，有可能是项目设置的问题,

这个web项目引用了另外一个java项目（项目B）,两个项目有一些相同的jar包，是不是这些相同的jar发布的问题呢，我把项目B的
Java EE Module Dependencies(项目B右键->Properties->Java EE Module
Dependencies)里的jar包引用去掉，问题解决了。

3.new server

简单有效可行的方法，把原来抛错的tomcat server delete，再重新 new 一个!!!别再纠结了哦～～嘎嘎 : P

重新建立一个Server，然后 switched back to the default of “Use workspace metadata”, 问题解决 ，OH YEAH！！！
