无法在emacs上启动苹果酒REPL

Question

Since I updated cider on my emacs a couple of days ago to CIDER 0.6.0alpha (package: 20140318.1539) I have not been able to run cider-jack-in.

If I try Mx cider-jack-in, I get the following error on the message buffer

 Wrong type argument: stringp, nil

If I run the command from a lisp buffer I get the following backtrace

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  find-file-name-handler(nil file-remote-p)
  file-remote-p(nil)
  start-file-process-shell-command("nrepl-server" "*nrepl-server*<2>" "lein repl :headless")
  cider-jack-in()
  eval((cider-jack-in) nil)
  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  ad-Orig-call-interactively(eval-last-sexp nil nil)
  call-interactively(eval-last-sexp nil nil)

Looking at the source in the debugger shows that the code for start-file-process-shell-command calls file-remote-p a couple of times with default-directory as its argument.

Now, I'm not sure if this is useful, since I'm getting way out of my depth here. But If I try and evaluate default-directory on the source buffer it returns a non-nil value ("/usr/share/emacs/24.3/lisp/").

I tried wiping out my .emacs.d directory and reinstalling cider and clojure mode, but I still get the same problem, and I have not seen any other thread talking about this specific behavior on the cider github page. So it looks like it's somehow related to my environment.

Any help on how to troubleshoot this issue would be greatly appreciated.

Santi.

You were affected by a regression introduced with the addition of the cider-jack-in over tramp feature ( commit ). I've just fixed the problem here .

In future you'd do better to report problems on the project's issue tracker. You're lucky I'm on stackoverflow as well. :-)
