How to set up lein cooper on Windows?

Question

I've followed the Leinigen install instructions on Windows (with c:\leinigen\ in my path, which is where lein.bat is). I'm now trying to use lein-cooper but this is giving me the following error:

java.io.IOException: Cannot run program "lein": CreateProcess error=2, The system cannot find the file specified

I get the above when I run lein cooper from a Powershell prompt. I've got an entire project where this does work on my colleague's OSX, but on Windows tit doesn't work.

I've created a smaller repro using the following project file:

(defproject cooper.repro "0.0.1"
    :dependencies [[org.clojure/clojure "1.9.0"]
                [org.clojure/clojurescript "1.9.946"]]

    :plugins [[lein-cljsbuild "1.1.7"]
            [lein-cooper "1.2.2"]
            [lein-figwheel "0.5.14"]]

    :source-paths ["src/"]

    :cooper {"cljs" ["lein" "figwheel"]}

    :figwheel {:http-server-root "./" :server-port 3000}

    :cljsbuild {:builds [{
        :id "dev" 
        :source-paths ["src"] 
        :figwheel true
        :compiler {
            :main hello-world 
            :asset-path "js/out" 
            :output-to "resources/public/exmple.js" 
            :output-dir "resources/public/out"
        }}]}
)

My src folder contains just a hello-world clojurescript file with only a namespace. If I run just lein figwheel from the command line instead it does work as expected (even though it doesn't do anything interesting).

At first I thought it was a path-related issue so I rebooted my machine but that didn't help.

Google search gives zero useful results.

Any tips on getting this fixed? Or should I file a bug (and if so: where? for figwheel, or for lein-cooper?).

For now, because we were using `npm` anyways, I just resorted to using [npm's Foreman package](https://www.npmjs.com/package/foreman). — Jeroen, Jan 03 '18 at 10:14
I've cross-posted this question [on lein-cooper's GitHub issues list](https://github.com/kouphax/lein-cooper/issues/11) because perhaps it's just a missing feature. — Jeroen, Jan 03 '18 at 13:46
so have you managed to solve the issue? I have same problem on Windows. — Twice_Twice, May 02 '18 at 08:44
@Twice_Twice Nope, sorry. I stuck with Foreman, and since last month I've moved on to another tech stack for my next project. — Jeroen, May 02 '18 at 14:15
I have same issue, interesting , if you rename `lein` to `lein.bat` then you run it . it works on my windows machine — Shawn Zhang, Aug 08 '19 at 04:57
