Build failed when Wordcount example code has been changed

Hi guys !

I have set up a single node cluster as per below link
http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/#run-the-mapreduce-job

I have tried to run Wordcount example.
$bin/hadoop jar hadoop-*--examples.jar wordcount dfsinput dfsoutput
It works.

> I have modified the code say printfs in Wordcount.java in
> ${HADOOP_HOME}/src/examples/org/apache/hadoop/examples/WordCount.java 

   I was thinking of doing these to see the changes :

  1 {HADOOP_HOME}$ ant build
  2 started daemons
  3 $bin/hadoop jar hadoop-*--examples.jar wordcount dfsinput dfsoutput
 
   but i get this dependency error in step 1.

Any help ?

Arun
