我正在使用Ant将战争部署到Tomcat服务器，但这给了我以下错误：

这是我用于此部署的Ant目标（这是引发异常的行）：
<target name="deploy-debug" description="Install DEBUG">
<deploy url="http://debug.webiste.ro:8180/manager" username="admin" password="password"
path="/debug-war" war="wars/debug-war.war"/>
</target>
我正在使用Tomcat 9.0.10和Ant 1.10.3。
我看到有人建议在tomcat_users.xml中没有正确定义tomcat用户。我已经对其进行了修改，但是当我尝试进行部署时，它仍然给我一个例外。我可以在浏览器中成功登录Tomcat管理器应用程序。这是我的tomcat_users.xml：
<tomcat-users xmlns="http://tomcat.apache.org/xml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
version="1.0">
<role rolename="tomcat"/>
<role rolename="manager-script"/>
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<user username="admin" password="password" roles="manager-gui,manager-script,admin-gui,admin-script"/>
</tomcat-users>
我要部署的war文件具有80 Mb，大于Tomcat的默认最大上载值（50 Mb）。我尝试将最大上传值增加到100 Mb，但仍然给我例外。
关于这个问题有什么想法吗？
