I believe this is caused by class loader visibility issue. Even if
your ant classes are there, it seems that your woproject.jar is
loaded in a different classloader, hence not seeing the ant classes.
I would suggest you add the woproject.jar into the initial ant
classpath within Eclipse to see if that solves it:
