Hi

Reading this resource in regular REPL:

$ clj
Clojure 1.9.0
user=> (require '[clojure.java.io :as io])
nil
user=> (slurp (io/resource "foo.txt"))
"Hi\n"
user=>

Import this project into Cursive and set up a REPL

Note that there is no evidence that resources is in the classpath above.

If instead you check via clj:

$ clj -Spath
src:resources:/Users/mfikes/.m2/repository/org/clojure/clojure/1.9.0/clojure-1.9.0.jar:/Users/mfikes/.m2/repository/org/clojure/spec.alpha/0.1.143/spec.alpha-0.1.143.jar:/Users/mfikes/.m2/repository/org/clojure/core.specs.alpha/0.1.24/core.specs.alpha-0.1.24.jar

I rolled intellij back to 2018.1.4 with cursive 1.8.0-eap3-2018.1 and I am now able to load files from my resources directory.

In case anybody was stuck on this, a workaround for the latest intellij and latest cursive plugin was to put the resources directory inside the src directory. Its gross, but hopefully will be unnecessary soon.

Running (System/getProperty "java.class.path") shows that the resources directory is not on the classpath.

All I had to do was mark the resources directory as a resource root in cursive and everything works great!
