hi, I am new to all this. I am on Ubuntu 16.04 64bit and did "sudo apt-get install leiningen" and did "lein uberjar" to get the cljminecraft-1.0.6-SNAPSHOT-standalone.jar file and put it into my ~/Bin/Minecraft/plugins directory, and then relaunched spigot (tried with both 1.12.1, and 1.12.2) inside ~/Bin/Minecraft. I got what appears to be a very similar error (see below). Then I tried "lein upgrade" and of course it told me:
$ lein upgrade
Upgrades should be done using apt rather than Leiningen itself.
the terrible terror:
This server is running CraftBukkit version git-Spigot-109b080-ab09b27 (MC: 1.12.2) (Implementing API version 1.12.2-R0.1-SNAPSHOT)

fwiw
$ java -version
java version "1.8.0_151"
Java(TM) SE Runtime Environment (build 1.8.0_151-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode)
[solved] Ok, apparently I had to get the raw "lein" script from https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein and then chmod +x it and put it into my path and sudo apt-get remove leiningen and then rebuild, I guess the apt lein was 1.x and the new lein is 2.x. The cljminecraft-1.0.6-SNAPSHOT-standalone.jar ended up in clj-minecraft/target/ and then I coped that over to my ~/Bin/Minecraft/plugins and restarted the spigot server and the error went away. Hopefully this will make sense to other clueless n00bs like I once was...
