今天研究对象是Ant，用于对msms系统进行Tomcat的自动部署。
遇到一个怪问题，百思不得其解：
通过ant depoly可以把msms.war部署到tomcat上。当然，要求这时候webapps下面没有msms目录。
看tomcat的纪录，加载msms.war正常，网页也可以打开。
通过ant undeploy，可以把msms卸载。Tomcat显示：
Undeploying context [/msms]
正常卸载了。问题是，去看webapps目录下面，居然有一个msms目录的残骸，里面保留的目录是
WEB-INF\lib
有以下几个文件残留着：
commons-digester.jar
commons-validator.jar
struts.jar
这时候msms目录也无法手工删除，必须停掉tomcat后才能删除。
我装的tomcat是5.5。不知道是否还有人遇到过这种情况，我反正是晕了。
build.properties文件如下：
tomcat.dir=C:/ApacheGroup/Tomcat5.5
tomcat.webapps=C:/ApacheGroup/Tomcat5.5/webapps
tomcat.manager.url=http://localhost:8080/manager
tomcat.manager.username=admin
tomcat.manager.password=xxxxxxxx
build.xml文件如下：
<?xml version="1.0"?>
