emacs+eclim for Java development not working

[Shiyuan]

Hi,
    I am learning Java and I am looking for a  Java development environment
in emacs.  The package emacs+eclim http://www.skybert.net/emacs/java/ seems
to provide what I want.

I tried to setup emacs+eclim following this instruction:
https://github.com/senny/emacs-eclim
After setting the variables in .emacs as instructed above, I tried to
involve M-x eclim-java-find-declaration I got the error: "You must specify
a valid pattern or element search"

Then I stepped through the elisp function: eclim-java-find-declaration():

(defun eclim-java-find-declaration ()
  "Find and display the declaration of the java identifier at point."
  (interactive)
  (let ((i (eclim--java-identifier-at-point t)))
    (eclim/with-results hits ("java_search" "-n" "-f" ("-o" (car i)) ("-l"
(length (cdr i))) ("-x" "declaration"))
      (eclim--find-display-results (cdr i) hits t))))

I notice that the function eclim--java-identifier-at-point correctly pickup
the class name in my code, but the class name has never been passed to the
command-line,
The Backtrace is :

shell-command-to-string("~/softwares/eclipse/eclim -command java_search -o
938 -l 12 -x declaration ")
* (eclim--parse-result (shell-command-to-string cmd))
* (let ((cmd (eclim--make-command args))) (if eclim-print-debug-messages
(progn (message "Executing: %s" cmd))) (eclim--parse-result
(shell-command-to-string cmd)))
* eclim--call-process("java_search" "-n" nil "-f" nil "-o" "938" "-l" "12"
"-x" "declaration")
* apply(eclim--call-process ("java_search" "-n" nil "-f" nil "-o" "938"
"-l" "12" "-x" "declaration"))
* (let ((res (apply (quote eclim--call-process) command-line))) (funcall
on-complete-fn) res)


Do I miss anything? I am on Mac 10.9 (mavericks) and Eclipse Kepler. Any
help is greatly appreciated. If you know any other emacs package can
provide similar functionality, please also let me know.

Bests,
Shiyuan
