I don't have a working Clojure environment yet, so I've done a few
things with the REPL and copy-paste of ant.clj.
I get a Clojure compilation error[1] if I use the define-ant-task
macro as you do in our commented code. If I manually expand
define-ant-task I get the expected exception from <fail> (that's what
you get when running that task):
user=> (doseq td (.getTaskDefinitions ant-project) (do (.execute
(instantiate-task ant-project (.getKey td)))))

I don't think you really want to execute the freshly defined task
right away as the macro currently does.
