Re: Noob: Getting (re)started with Clojure on OS X
I would even argue against using central profiles. I think it obscures
behavioural differences between machines and can impair reproducibility.
Arguably better to have all deps in project where possible.

Re: Noob: Getting (re)started with Clojure on OS X
[cider/cider-nrepl "0.8.2"]
is quite old. It looks like lein 2.9.1 (as of 2.8.2) uses a newer version
of nrepl that requires cider-nrepl 0.18+ or something along those lines.
In newer versions of cider, you may not need to include this plugin at all.
I know that the "jack-in" commands of cider can do it automatically for you
at least. If removing the dep works fine for your workflow, I'd stick with
that. Less is more. :-P

Hello Sean,

Many thanks for the reply.
My ~/.lein/profiles.clj file looks like
{:user {:plugins [[cider/cider-nrepl "0.8.2"]]}}
What should it look like?
*
I've used Java quite a bit, and my CLASSPATH is extensive.
It’s set in my ~/.bashrc
What’s my next step?
Best,

Check what’s in your ~/.lein/profiles.clj file – that’s usually the cause of
bizarre errors that people report with Leiningen.
Also check your environment variables: env|fgrep CLASSPATH
Per the warning, you probably want to remove whatever is setting that (from one
