我在运行tomcat ant任务时遇到问题。我发现了几个类似的案例，但没有一个有帮助：
ant安装以部署Tomcat Web应用程序失败，出现权限问题
为什么Ant在部署时返回403？
Ant Tomcat 7重新加载文件NotFoundException
版本：
- 操作系统：Windows 7 x64 Professional
- Java版本：1.6.0_25
- Ant版本：1.8.3
- Tomcat版本：7.0.011
我的tomcat users.xml:
<tomcat-users><role rolename="manager-script"/>
<user username="script" password="script" roles="manager-script"/>
<role rolename="manager-gui"/>
<user username="manager" password="manager!" roles="manager-gui"/>
</tomcat-users>
Ant脚本的一部分：
<property name="app.name" value="london"/>
<property name="manager.url" value="http://localhost:8081/manager/text"/>
<property name="manager.user" value="script"/>
<property name="manager.password" value="script"/>
<property name="update.filename" value="update.war"/>
<taskdef name="tomcatStart" classname="org.apache.catalina.ant.StartTask"/>
<taskdef name="tomcatStop" classname="org.apache.catalina.ant.StopTask"/>
<taskdef name="tomcatDeploy" classname="org.apache.catalina.ant.DeployTask"/>
<target name="main">
<tstamp/>
<tomcatStop
url="${manager.url}"
username="${manager.user}"
password="${manager.password}"
path="/${app.name}"
/>
<tomcatDeploy
url="${manager.url}"
username="${manager.user}"
password="${manager.password}"
path="/${app.name}"
war="file:${update.filename}"
/>
</target>
控制台输出（StopTask）：

奇怪的是，我让它工作了几次，但现在它再也不工作了。
另一个奇怪的事情是
StartTask和StopTask生成FileNotFoundException，但
DeployTask生成java.io.IOException:服务器返回HTTP响应代码：403…
该错误是否可能是由路径中编码的（%2F）斜线符号引起的？
非常感谢）
看起来所有设置都正常：
- 我删除了Tomcat文件夹
- 解压缩的新副本
- 应用的设置
现在一切都正常了。
我很遗憾没有早点检查。
