Leiningen unable to start a REPL: "Unable to resolve symbol: create in this context"

Question

I'm just switching from Cursive (IntelliJ IDEA) to Emacs

But I cannot launch REPL from neither CIDER nor lein...

It just says Unable to resolve symbol: create in this context

But in my code I'm not calling create

Most importantly but strangely, lein jar can compile it successfully!

1. The repo: https://github.com/freeze-dolphin/Dumortierite/tree/master/clj-module

2. Launching REPL in 'simpler' project is successful

Answer 1

After some experimentation, the problem seem to be with this line:

(ns io.sn.dumortierite.clj_module.items
  (:import 
    ...
    [io.sn.dumortierite.utils ClojureUtils ItemEffectUtils]
    ... 
  ))

You don't have the library mentioned present in your project. In fact, observe:

~/expr/so/Dumortierite/clj-module > d lib lib/**/*
drwx------ 3 alan alan 4096 Jun 15 09:17 lib/
drwx------ 2 alan alan 4096 Jun 15 09:17 lib/Dumortierite-0.1.0.jar/

Note that the "JAR" file is actual a unix directory.

There may be other problems, but this one is definitely a blocker.
