无法运行 Ant 文件

Question

当我通过命令提示符运行 ant 文件时，我会得到如下错误：

我还添加了 jcommander jar 文件和 class pathelementlocation。但它仍然不起作用。引导我伸出援手。

Answer 1

我明白了。实际上在文件集标签中我提到了默认路径

<fileset dir="${lib-dir}">

示例：C:/Project/Jars

但在我的项目中，我没有创建在 file set dir

中提到的确切路径

在项目中我保留了像 C:/Project/Jars/lib

这样的项目结构

现在，我将项目结构中的库路径更改为 C:/Project/Jars，现在可以使用了。
