Error when trying to run ClojureScript on Windows

I try to run ClojureScript "hello-world" project on Windows 10 Home 22H2 19045.4529. I follow documentation from https://clojurescript.org/guides/quick-start and get following output:

C:\Users\1\Documents\hello-world>java -cp "cljs.jar;src" cljs.main --compile hello-world.core --repl

Changing structure of application didn't help. (removing hello_world folder)

Solution

  • I suspect you have the Java JRE installed, whereas Clojure(Script) need the full Java JDK. Not exactly sure how that would lead to a Stack Overflow but try installing a full JDK variant. At least Version 11+, otherwise you'll run into issues a bit later again.

    Version 21 is the current LTS (Long Term Support) Release, so I'd recommend that.
