The attached antlib.xml would need to go into clojure.jar under the
directory clojure (the rest of the attachment is a patch to build.xml
that takes care of this).
But in reality this approach doesn't get us very far since the whole
classpath logic is too complex to make it really useful when
implemented in XML instead of Java or Clojure.
Oh, an example for clj:compile is in the patch, but I'm cheating - it
won't work that easily for code other than Clojure itself.
<clj:script> works and may actually be usuable as is:
<project xmlns:clj="antlib:clojure">
<taskdef uri="antlib:clojure">
<classpath location="clojure.jar"/>
</taskdef>
<clj:script script="hello.clj">
<classpath>
<classpath location="clojure.jar"/>
</classpath>
</clj:script>
</project>
and hello.clj
(println "Hello, world!")
result in
Buildfile: testantlib.xml
[java] Hello, world!
