Incorrect plugin spec yields NoSuchFieldError: DEF_CONTENT_CHARSET

[dirtyvagabond]

If a non-existent artifact is specific in the plugins file, Drake explodes with an incredibly arcane and unhelpful stack trace.

Example plugins.edn:

{:plugins [[dirtyvagabond/unicorn "0.1.0-SNAPSHOT"]]}

Yields:

Exception in thread "pool-2-thread-1" Exception in thread "pool-3-thread-1" Exception in thread "pool-1-thread-2" Exception in thread "pool-1-thread-1" java.lang.NoSuchFieldError: DEF_CONTENT_CHARSET

Potential fix courtesy @stfactual :

On project.clj line 32, [com.cemerick/pomegranate "0.2.0" :exclusions [org.apache.httpcomponents/httpcore]] works for me. It failed when excluding the one from the S3 library.

I can't explain your original bug as stated, but I can explain something similar. clj-s3 and pomegranate each bring in a different version of httpcore (4.2 for s3, 4.1.x for pomegranate). Drake failed for any plugins.edn when I excluded 4.2, so I instead excluded 4.1.x. That made it work both for the existing library and for nonexisting.

If you have a library in your local Maven repository, it's possible it wouldn't make an HTTP request. That might be the reason things worked when your library existed. I used [funnyplaces "1.2.3"], which wasn't in my local repo but does exist on clojars, and it failed.

This error message looks more like a version mismatch. Are you sure it
comes from non-existent artifacts?

No, not sure at all. In Spencer's quote, he's suggesting it can happen when Pomegranate triggers a dep request over the wire
