Hi Mimmo,
Unfortunately, there's no way to do that right now. I can't even think of

have a single :source-path and is not otherwise customizable. If you

One other thing I ought to mention is that your *.cljs files need to be
arranged in an appropriate directory structure (i.e. the directories must
match the namespaces):
/src-cljs/live/helper/webTemplate.cljs
/src/cljs-test/helper/webTemplate/test.cljs

For what you're trying to do, :externs is not the solution.
Ultimately, all you need to do is make sure that both src-cljs/live and
src-cljs/test are on the classpath at compile time. The easiest way to do
this would be to put both builds into the same project:

The problem is that take-while is lazy, so it does not actually perform the

How would that affect Java interop? It seems like it would make Clojure

Hey,
I just released a major update to the lein-cljsbuild plugin for

PhantomJS.
* Support for running ClojureScript

appealing. A couple of notes:
