当我输入命令 ant reload 时，服务器会生成 eception。我在我的 buil.xml 文件中编写了 ant reload 脚本。但服务器无法重新加载它。例外是

根据异常，看起来 ant 无法连接（拒绝连接）到您的 tomcat 服务器。

仔细检查 tomcat 是否运行了 manager webapp，并且 ant 正在连接所有正确的信息。

默认情况下，Tomcat 没有启用任何管理器 Web 应用程序用户。您需要取消注释用户并在 $TOMCAT_HOME/conf 中找到的 tomcat-users.xml 中为他们提供管理员角色。

然后，ant 使用该用户及其密码连接到该用户。
