Simple noir server won't start

Question

I've just started to learn Clojure, and thought a good way to dive into it would be to write a simple Noir website.

I've installed leiningen, did lein self-install and installed the lein noir plugin. When I create a dummy project ...

>> lein noir new test-noir
Creating noir project:  test-noir
Creating new dirs at:  /Users/pdeuchler/Documents/workspace/test-noir
Adding files...
Project created!
>> cd test-noir/

And then try to run it ...

>> lein run

I get an error which I googled, but resulted in no relevant results.

Can anyone help me out?

That should work. Out of curiosity, what happens when you run lein deps before lein run? Also, what version of Leiningen (lein -v) are you running? And finally what is in your project.clj? — Julien Chastang, Jun 07 '12 at 21:17
I get this stack trace when running `lein deps` http://pastebin.com/npSA5rzQ. I'm running Leiningen 1.6.1 on Java 1.6.0_31 Java HotSpot(TM) 64-Bit Server VM. This is my `project.clj` (unedited from `lein noir new test-noir`) http://pastebin.com/NfYbH1dh — pdeuchler, Jun 07 '12 at 21:24
Grab the latest stable Leiningen which is at least 1.7.1, and start over. Let us know what happens. — Julien Chastang, Jun 07 '12 at 21:36
Updated Leiningen... when running `lein deps` I get what seems to be the same stack trace... http://pastebin.com/8gTQyBx2 — pdeuchler, Jun 07 '12 at 21:48
Something is up with Maven and your .m2 directory. This is not a problem with Clojure or lein. Try moving the .m2 directory out of the way and give it another shot. — Julien Chastang, Jun 07 '12 at 22:01
