Hi,
I've seen some reports on this list that Webtest wouldn't work with
Ant 1.6.0. The reason is that we (the Ant team) have broken backwards
compatibility for third-party TaskContainer implementations and didn't
notice it until after 1.6.0 has been released.
Fortunately there is a way to change the custom TaskContainers in a
way that they will work with both Ant 1.5.x and Ant 1.6.x[1] and the
patch that I've attached (against build 392) should work. I haven't
tested it thoroughly though since the self test doesn't seem to pass
with an unmodified version of Webtest for me either.
Cheers
Stefan
