The config.clj File looks like this:

    (ns edu.upc.modelvsdocument.config
  (:use [edu.upc.modelvsdocument.utils]
        [com.rpl.specter]
        [edu.upc.modelvsdocument.schemas]
        [edu.upc.modelvsdocument.utils]
        [clojure.pprint])
  (:require [clojure.java.io :as io]
            [clojure.spec :as spec]
            [clojure.spec.test :as stest]
            [edu.upc.modelvsdocument.schemas :as t :refer :all]
            [clojure.walk :as walk]))

I read a lot of stuff about clojure/spec/alpha__init.class, but i don't know if this relates to my problem. Please provide a desperate clojure neewbie some wisdom:)

We'd be happy to help over in #clojurians slack, but I think it would include a lot of back-and-forth about your setup and basic clojure info, and not a productive use of this ask site.

ok, thank you for your suggestion!:)

My assumption is that you're using Clojure 1.9+ but not including the spec.alpha and core.specs.alpha libraries that it depends on.

As Justin said in the other answer, might be easier to get interactive help in the Clojurians slack.
