Clojure is odd because you can't reliably add to the classpath at
runtime. Because of this, I unpack all my dependencies in one place
(target/dependency) so the classpath never changes. Then I use this
function to start Slime:
(defun slime-project (path)
"Setup classpaths for a clojure project and starts a new SLIME session.
Kills existing SLIME session, if any."
(interactive (list
(ido-read-directory-name
"Project root: "
(locate-dominating-file default-directory "pom.xml"))))
(when (get-buffer "*inferior-lisp*")
(kill-buffer "*inferior-lisp*"))
(setq swank-clojure-binary nil
swank-clojure-jar-path (expand-file-name "target/dependency/" path)
swank-clojure-extra-classpaths
(mapcar (lambda (d) (expand-file-name d path))
'("src/" "target/classes/" "test/"))
swank-clojure-extra-vm-args
(list (format "-Dclojure.compile.path=%s"
(expand-file-name "target/classes/" path)))
slime-lisp-implementations
(cons `(clojure ,(swank-clojure-cmd) :init swank-clojure-init)
(remove-if #'(lambda (x) (eq (car x) 'clojure))
slime-lisp-implementations)))
(save-window-excursion
(slime)))
I use a single Emacs instance per project. It's possible to have
multiple Slime sessions in an instance, but I find this gets confusing
and would rather manage them separately.
You'll need to remove the call to locate-dominating-file if you're not
on Emacs 23 yet.

On my machine it uses the current working directory of whatever buffer
was open when you launched Slime. Maybe try opening one of your project
files before launching?
