When I do "lein run" now, I get "Exception in thread "main"
java.lang.ClassNotFoundException:".
I'm early in the process of getting a Clojure development environment set
up--I coded a lot of LISP years ago and want to dust off my skills with
Clojure--and I have previously successfully done the following on Mac OS X
10.7.5:
- Installed Leiningen using Brew--this installed a V1 version
- Created and run projects ("lein new"; "lein run"; etc.)
- Everything worked great
However, I wanted to use nREPL in Aquamacs, so I needed lein 2.x. The only
way I could get lein2 installed was using these
steps<http://mikeebert.tumblr.com/post/30368615037/upgrading-to-leiningen-2>.
After completing them, I successfully tested nREPL inside Aquamacs. Again
things seemed to work great.
But while "lein new" still works, "lein run" does not. I get the following
exception:
Exception in thread "main" java.lang.ClassNotFoundException:

My project.clj looks like this:

:description "http hello"
; :url "http://example.com/FIXME";
; :license {:name "Eclipse Public License"
; :url "http://www.eclipse.org/legal/epl-v10.html"}
:dependencies [[org.clojure/clojure "1.4.0"]])
I've done a lot of searching and tried several different things, to no
avail. I'd appreciate any pointers you can give me. Thanks ...
