I have been using ubergraph last few weeks up until this morning, but now am having compiling problem.

In my project.clj's dependencies, ubergraph is declared:

(defproject graph-alg "0.1.0-SNAPSHOT"
:dependencies [[org.clojure/clojure "1.10.0"]
               [ubergraph "0.8.2"]]

In my core.clj, I have

(ns gaph-alg.core (:require [ubergraph.core :as uber]))

Even with these settings, when compiling in emacs, I kept having this error message:

*Error compiling c:/.Clojure/snippets/graphworks/graph-alg/src/graph_alg/core.clj at (1:1) #:clojure.error{:phase :compile-syntax-check, :line 1, :column 1, :source "c:/.Clojure/snippets/graphworks/graph-alg/src/graph_alg/core.clj"}

  1. Caused by java.lang.Exception namespace 'ubergraph.core' not found*

I recreated new projects using lein few times with above setting, but still have same issue like above.

I am not sure whether this comes from emacs cider-repl or something else.

Does anybody else know how to handle this problem? Thanks in advance.

    You can narrow the problem by trying it in a REPL free of Emacs and CIDER. For example, "lein repl". Commented Apr 19, 2021 at 23:08
  • The error message means that Ubergraph is not on the Java classpath. You can inspect the classpath in the REPL by evaluating (System/getProperty "java.class.path"). Commented Apr 19, 2021 at 23:12
  • I checked the java.class.path and found ubergraph-0.8.2.jar in the path. Commented Apr 20, 2021 at 0:56
  • I tried: new lein project, added the dep, started a repl and did (:require [ubergraph.core :as uber]) - worked. Since you stated you already tried with a fresh template. Is there a chance you could share your project in full (e.g. on some git site)? Commented Apr 20, 2021 at 16:41

    I found that this error comes from my dumb mistake - I added ubergraph & dorothy in my project.clj file with dorothy version 0.0.7, which conflicts with ubergraph's dorothy version. After I downgraded dorothy version to 0.0.6, which is the same version that ubergraph is using, it works fine. Thank you so much guys - Phill & cfrick - for your helpful comments!
