硒-ANT-测试

我写了一个build.xml，它在其中产生一个错误，声明"taskdef元素的classname属性未定义"

这是我的build.xml

<?xml version="1.0" encoding="UTF-8"?> 
 <project name ="AutomationScripts" default="test" basedir=".">

您需要在"classname"属性中指定实现数据类型的类。根据Ant taskdef文档（更具体地说是typedef），这个任务有两个必需的属性——"name"one_answers"classname"，除非指定了"file"或"resource"。属性"classpath"仅定义可以找到"classname"中指定的类的位置。
