AmazonEMR教程示例不使用ant编译

我正在尝试做亚马逊emr（elastic mapreduce）的教程https://www.youtube.com/embed/zsu8n2povbm?rel=0&hd=1;自动播放=1
我下载了教程示例http://elasticmapreduce.s3.amazonaws.com/training/wikipedia-lab.tgz，计算维基百科文档集合中的bigram数。我一开始就被卡住了：

2. Build the job jar

   [On your dev machine]

   % ant clean job

   This will create the wikipedia-ngrams-job.jar Hadoop job jar
   file in your build sub-directory. If you have Hadoop installed on
   your development machine, you can try running it locally via:

   % hadoop jar build/wikipedia-ngrams-job.jar -inputfile src/test/resources/enwiki-split.xml -outputdir build/test

   This will generate text output files in build/test/raw-counts and build/test/sorted-counts.
   To view the results, you can dump the output (these are text files), e.g.

   % cat build/test/sorted-counts/part-r-00000

以下是终端输出：

> ant clean job
Buildfile: /Users/jfk/work/data/aws_s3/wikipedia-lab/build.xml

clean:
     [echo] cleaning wikipedia-ngrams
