"The clojure executable isn’t on your ‘exec-path’" even though lein is on my exec-path (macOS)

Question

I have the following exec-path (according to describe-variable):

("/usr/local/bin/" "/usr/bin/" "/bin/" "/usr/sbin/" "/sbin/" "/usr/local/Cellar/emacs-plus/25.3/libexec/emacs/25.3/x86_64-apple-darwin16.7.0/")

This is the lein executable path:

/usr/local/bin/lein

This is what happens when I run cider-jack-in:

The clojure executable isn’t on your ‘exec-path’

What gives?

Edit: (cider-lein-command is lein)

If I create a project with lein new and go into that project, it works. — The Unfun Cat, Feb 26 '18 at 17:19
what about cider-jack-in-command? https://github.com/clojure-emacs/cider/blob/master/cider.el#L288 maybe project-type isn't set to lein. — Jonah Benton, Feb 26 '18 at 21:55
`cider-lein-command is a variable defined in ‘cider.el’. Its value is "lein"` — The Unfun Cat, Feb 26 '18 at 22:00
Right, but it's looking for the clojure command, not the lein command. "clojure" is an executable that was introduced with the new cli tool: https://clojure.org/guides/deps_and_cli — Jonah Benton, Feb 26 '18 at 22:16
Thanks for the help @Jonah B. Could you please add your comment as an answer so I can accept it :) ? — The Unfun Cat, Feb 27 '18 at 17:33
I get this problem if i do `restart` in the cider repl. How do I configure cider to use lein? — ackerleytng, Mar 03 '18 at 06:09

Looks like cider is looking for the clojure command, not the lein command. "clojure" is an executable that was introduced with the new cli tool:

Yes so... I'm having the same problem. I swear I was able to use ClojureCLI with CIDER, but I'm in a new system, with new Emacs, and can't do that anymore. I'm not interested on Lein. – jgomo3 Jan 28 '22 at 22:32

I would just like to build onto Jonah Benton's answer, in response to ackerleytng's question on how to configure cider to use lein instead:

To change cider build command from clojure to lein, set lein as the value for variable cider-default-repl-command.

For the emacs beginner, you can see and change a variable value with keys C-h v.
