'How to setup clojure.main?

In reference to the thread here : Clojurescript: Error: Could not find or load main class clojure.main

Where (in which directory) do we need to keep the clojure.jar? Should it be in the lein folder or in the folder where lein folder exists?

I am trying Clojure for the first time and have already spent a large amount of time in setting up Clojure and lein. But still facing the same error.

Open a project with lein

$ lein new myproject
$ cd myproject

There in src/<projectname>/core.clj put your code - and from inside this myproject folder start lein: lein repl It will run the core.clj code - and say sth like:

nREPL server started on port 46297 on host 127.0.0.1 - nrepl://127.0.0.1:46297

So you can connect with this repl from emacs using M-x cider-connect and choose localhost and as port 46297 or whatever is given as port in that nREPL line!
