After upgrading Clojurescript '1.9.494' getting JSC_PARSE_ERROR

After upgrading my Clojurescript version 1.8.51 to 1.9.494 I'm getting the following error:

And it says Successfully compiled but it does not reflect the new code.

Successfully compiled "resources/public/js/app.js" in 11.472 seconds.

When I switch to 1.8.51 version everything just works fine.

Solution

  • This is a bug in closure-compiler. It's been fixed, but we're just waiting on the next version to be released.

    Edit: It has now been released - version 20170409
