Clojurians Log v2

Hey all, I'm trying to run the example Sente project (https://github.com/ptaoussanis/sente/tree/master/example-project), however I'm getting quite a few errors that I suspect are related to my environment. I can't figure out for the life of me what the problem is though. Attached is the feedback/errors I get when I try to run lein start. My lein version is Leiningen 2.8.1 and Java version is Java 1.8.0_222 OpenJDK. All on Ubuntu 18.04.

Reflection warnings are warnings that executing certain interop calls may be slow, but they should still work. You can ignore those for now, unless performance for your application is terrible and you want to improve it.

The file containing the full report should give more clues.
