when I compile floodlight, I get the following error:

[zhangdongdongdong]

I use the following steps to install floodlight:

sudo apt-get install default-jdk
java -version
sudo apt-get install build-essential ant maven python-dev eclipse
git clone git://github.com/floodlight/floodlight.git
cd floodlight
ant

But when I compile floodlight, I get the following error:

`Buildfile: /home/zddd/yanzhen/floodlight/build.xml
[taskdef] Could not load definitions from resource tasks.properties. It could not be found.

What's wrong with that?
