在Pig 0.10.0中 piggybank源程序已经包含在contrib文件夹中，但是没有编译成jar包形式，需要自己用ant编译,官方的参考文档https://cwiki.apache.org/confluence/display/PIG/PiggyBank，但似乎只适合以前的版本
下面是我的编译步骤，仅供参考，过程中有很多自己不懂的地方，希望起到一个抛砖引玉的作用：
第一步：进入build.xml所在文件夹
[root@master java]# cd /home/swxing/pig-0.10.0/contrib/ [root@master contrib]# ls CHANGES.txt penny piggybank zebra [root@master contrib]# cd piggybank/ [root@master piggybank]# ls java [root@master piggybank]# cd java [root@master java]# ls build build.xml lib src
第二步：使用ant编译
[root@master java]# ant -file build.xml
提示错误：
BUILD FAILED
/home/swxing/pig-0.10.0/contrib/piggybank/java/build.xml:92: /home/swxing/pig-0.10.0/build/ivy/lib not found.
看了一下的确不存在这个目录，但是看到pig-0.10.0根目录下有ivy文件夹，然后我就在pig-0.10.0目录下自己建了一个子目录：build/ivy/lib，然后把ivy文件夹和lib文件夹都拷贝进去了
这个地方我也不知到原因。。。。然后再用ant编译,提示80个错误。。。

仔细看发现都是在/piggybank/storage/中java文件的错误，因为我的机子没装hive，所以提示没法引用，反正现在也永不到storage中的自定义函数，所以我就将storage中的内容清空了，再编译，就okay了。
附上我自己编译的piggybank jar包
