使用 Ant 构建 Pig 的难度

Question

我是一个猪新手，一直试图让它在我的 Windows 7 机器上运行。我的 hadoop (2.4.0) 在我的本地机器上运行良好，但是每当我尝试运行一个简单的 Pig 脚本时，每当我尝试转储文件的内容时它都会引发错误。

找到了here 的类似问题的解决方案，我尝试使用 Ant 重建我的 Pig (0.12.1)。 每当我跑步时

ant clean jar-withouthadoop -Dhadoopversion=23

我收到以下错误：

我在这里做错了什么？我是缺少文件，还是 build.xml 中的配置问题？

编辑：我已经从 cmd 和 cygwin 终端运行了这个命令。它们都输出相同的错误。

EDIT2：我正在使用 Ant (1.9.4) 构建

最终编辑：原来我需要将 pig src 存档（pig-0.12.1-src.tar.gz）移动到 cygwin 主目录，解压缩，cd 到解压缩的存档并运行命令。

Answer 1

我遇到了同样的问题。我通过在我的 cygwin 家中通过 cygwin 编译 pig 来解决它。

我的常春藤设置是这样的：
