ClassNotFoundException using :preloads

[jlo1]

Trying to use the :preloads key (based off the project.clj and env.all in this repo: https://github.com/areina/elfeed-cljsrn/blob/master/project.clj#L46), but hitting some issues, either locally or on CircleCI.

Using ['env.all], I can get circle ci to preload the file and run the tests successfully, but I get a figwheel compilation error when trying to start figwheel locally:

The Vector at (:cljsbuild :builds 2 :compiler :preloads) contains a non-conforming value: 
  'env.all
It should be a Symbol

  {:cljsbuild {:builds [{:compiler {:preloads ['env.all
                                               ^---- The value at key 0 doesn't conform]}}]}}

If I remove the quote and change it to [env.all], I'm able to start figwheel locally without any errors, but the circle ci build fails with the following stacktrace:

Any idea how to fix this?

This is a common mistake you can't quote things in a project.clj, you must leave the quote offf

Thanks for the response @bhauman! Leaving the quote off however results in the ClassNotFoundException (stacktrace is pasted above). Any idea how to workaround that?

[bhauman]

That stacktrace is saying that env.all doesn't exist. But for questions like this you should head over to the Clojurians slack.
