Leiningen commands suddenly return errors

Question

When running lein commands, I get this error:

Failed to read artifact descriptor for com.cognitect:transit-clj:jar:0.8.309

I have no clue what's going on, I've had the error for a day now. These are my dependencies:

  :dependencies [[ch.qos.logback/logback-classic "1.2.9"]
                 [com.novemberain/validateur "2.6.0"]
                 [com.timezynk/assembly-line "1.0.0"]
                 [com.timezynk/useful "1.19.0"]
                 [compojure "1.7.0" :scope "provided"]
                 [congomongo "2.5.1" :scope "provided"]
                 [org.clojure/clojure "1.11.1" :scope "provided"]
                 [org.clojure/tools.logging "1.2.4"]
                 [slingshot "0.12.2"]
                 [tortue/spy "2.4.0"]]

Edit: It looks like a Maven error, and maybe it is, but I don't know anything about Maven, and I can't find any info that is readable to me.

Found a solution. Completely cleaning out the repository solved the issue:

cd ~/.m2/repository
sudo rm -rf *
