即使正确设置了ANT_HOME、JAVA_HOME和 PATH 变量，我也无法运行 ant。任何回应都值得赞赏。
谢谢！

ANT_HOME is set incorrectly or ant could not be located. Please set ANT_HOME.
C:UsersRahul>
实际上
ANT_HOME设置不正确，因为ANT_HOME指的是 Ant 安装目录的路径，该目录是 bin 的父目录。并且您设置的路径到 bin 是不正确的。
执行以下操作
ANT_HOME = C:UsersRahulDownloadsapache-ant-1.8.4
Ant Home 应该是
ANT_HOME = C：\Users\Rahul\Downloads\apache-ant-1.8.4
同样在环境变量中编辑路径系统变量并向其添加以下路径
;C：\Users\Rahul\Downloads\apache-ant-1.8.4\bin
