Hi everybody!

I am quite new concerning to Eclipse and I hope that my problem is not so hard and somebody will be able to help me. The problem is that I would like to use eclipse.buildScript ANT task in Eclipse to generate build files but I always end up with an error saying that Ant could not find the task or a class this task relies upon.

Thank you beforehand!
