"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)

(from the comment)

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:
