ClojureScript Quick Start - Error: Could not find or load main class clojure.main

[gilmoretj]

I suspect there is a MS Windows-specific configuration step missing from the Quick Start guide (https://github.com/clojure/clojurescript/wiki/Quick-Start).

I was alright until I reached "Auto-building". Running the compilation step for watch.clj, I got the error message "Error: Could not find or load main class clojure.main".

I carried on to the "Running ClojureScript on Node.js" section only to encounter the same error running the node.clj build.

The initial build.clj build worked fine.

I am having the same issue with the NodeJS quick-start section on OSX 10.10.1.

Notice that the Windows steps needs the classpath bits to be in quotes. Or did you already try that?

java -cp "cljs.jar:src" clojure.main watch.clj

And all the previous steps worked for you?

David,

Apologies for my delay.

I have repeated the Quick Start guide given your advice and managed to proceed much further. I skipped both the Browser and Node REPL sections but managed to get the watch build and node build working fine.

I have downloaded the rlwrap tar and a 64bit edition of Cygwin and will have to give the REPL sections a go.

Thanks.

I bumped into this problem this morning. For Windows, in addition to the quotes, you also need to change the colon to a semi-colon, giving:

java -cp "cljs.jar;src" clojure.main watch.clj
