lein cljsbuild once release doesn't work

[be9]

The generated project.clj file doesn't have :output-dir setting for cljs release build, and lein cljsbuild once release fails without it:

~/hacks/omtest∴ lein cljsbuild once release
Compiling ClojureScript.
Compiling "resources/public/js/omtest.js" from ["src/cljs"]...

However if I add this line:

                                 :output-dir "resources/public/js/outrelease"

I get this:

I'm quite new to clojure(script), might be something trivial. But the generated template doesn't work "off the shelf" for me.

[jalehman]

I actually had this issue the other day and forgot to apply the patch to this repo. Turns out that it's due to my using old references to react js in the :preamble and :externs of the builds. Just deployed a fix -- see if that does the trick.

[jalehman]

Also, the index.html comes configured for the dev build. You'll need to change it as shown here.

[jalehman]

Hm. That didn't seem to fix it. Will check into it.

[be9]

@jalehman thanks! what's the exact change that should be applied to index.html? Is there also a way for index.html to work for production and dev environments?
