This addresses #263. I couldn't get ./build install to run without errors even before I made these changes. Let's see if circleci passes.

Great job on this! 👍

Cool I'll make those changes. I'm having a hard time testing this in emacs, how do you go about testing this within emacs? When I do a lein install, I don't get the same behavior as when I run in the a separate lein repl (with the appropriate profiles). Maybe I should try renaming the project and deploy to my personal clojars to get it to work.

runnig ./build install i get the following:
Exception in thread "main" java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter, compiling:(cljs/util.cljc:1:1)

I think I know my issue with build.sh, I keep forgetting about the proper profile.

Testing in emacs is giving me different behavior. It's downloading on every invocation of jack-in. It is getting the gzipped version at least :-).

[paulrd]

Is make inline-deps always required before I do lein install?

[paulrd]

ah! :force true is set! why!?

[paulrd]

Ah, ok it's not a bug. The default custom variable cljr-populate-artifact-cache-on-startup is true. Changing it to nil fixes the issue. I might open an issue there just as a reminder.

[paulrd]

One more thing I should change I should either keep the map sorted or resort it when loading from cache file.

Looks good other than a final nitpick! 👍
