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

[didibus]

Expected behavior

Given a clojure-mode buffer.
Given we have no project.clj
When running cider-jack-in
Then we are connected to an empty standard Clojure REPL

Actual behavior

We are instead greeted with the following error: user-error: The clojure executable isn’t on your ‘exec-path’, and cider does not start a repl and does not jack-in.

Steps to reproduce the problem

C-x b into a new buffer.
M-x clojure-mode to switch major mode to clojure.
M-x cider-jack-in

hi @didibus this seems most likely a problem with your setup. I think a simple remedy is to add lein to your path. You can do this inside of emacs as well with

(add-to-list 'exec-path "lein/path")

The actual problem here is different - since CIDER 0.17 repls outside projects are started using clojure ... instead of lein repl. But I don't think that the clojure script is present on Windows, so we should probably make the default command selection a bit smarted and check if clojure is present, falling back to lein.

Ya, emacs can find lein properly, for example, I can cider-jack-in given a project.clj file is present. But it seems to try and use tools.deps to start a repl without a project. And since that's not yet available on Windows, lein should still be used.

Hi! As the windows support for clj is looming and I've started to work on few projects that unfortunately are scafolded around clj instead of lein, what's the stat with this?

I seem to have similar issue to above, which I believe is rooted into to the fact that current windows clj is mainly run through PowerShell. Any suggestions for some workarounds for the time being?
