Here's what I've added to the swank-clojure codebase. It supports the
somewhat standard src/ and classes/ project layout style as well as one
based on Maven conventions.
(defun swank-clojure-project (path)
"Setup classpath for a clojure project and starts a new SLIME session.
Kills existing SLIME session, if any."
(interactive (list
(ido-read-directory-name
"Project root: "
(if (functionp 'locate-dominating-file) ; Emacs 23 only
(locate-dominating-file default-directory "src")
default-directory))))
;; TODO: allow multiple SLIME sessions per Emacs instance
(when (get-buffer "*inferior-lisp*") (kill-buffer "*inferior-lisp*"))
(setq swank-clojure-binary nil
swank-clojure-classpath (let ((l (expand-file-name "lib" path)))
(if (file-exists-p l)
(directory-files l t ".jar$"))))
(add-to-list 'swank-clojure-classpath (expand-file-name "src/" path))
;; For Maven style project layouts
(when (or (file-exists-p (expand-file-name "pom.xml" path))
(file-exists-p (expand-file-name "project.clj" path)))
(dolist (d '("src/main/clojure/" "src/test/"
"target/classes/" "target/dependency/"))
(add-to-list 'swank-clojure-classpath (expand-file-name d path)))
(add-to-list 'swank-clojure-extra-vm-args
(format "-Dclojure.compile.path=%s"
(expand-file-name "target/classes/" path))))
(run-hooks 'swank-clojure-project-hook)
(setq 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)))

This version has a hook, so you can customize your one-off project
settings using that.
Thoughts?
