tag py-compile errors,[develop with Eclipse and pyAnt]

[shuimuliang at gmail.com]

I configured Eclipse according to the paper
http://www.ibm.com/developerworks/library/os-ecant/index.html.
But, when I build the ant file,it failed with the following message:
Could not create task or type of type: py-compile.

I hava added pyAntTasks.jar to ${eclipse}/plugins/
org.apache.ant_version/.

How to solve this problem,thanks.
