I started to play with the Kit Web Framework and followed the instructions to build the default example, https://kit-clj.github.io/docs/guestbook.html#guestbook_application
> clojure -Ttools install com.github.seancorfield/clj-new '{:git/tag "v1.2.404"}' :as clj-new > clojure -Tclj-new create :template io.github.kit-clj :name kit/guestbook > cd guestbook I then try to start a CIDER repl by typing: > clj -M:dev:cider This fails with a class-not-found error: java.lang.NoClassDefFoundError: org/xnio/channels/StreamSourceChannel The complaint comes from Exception in thread "main" Syntax error compiling . at (ring/adapter/undertow/request.clj:10:17) I can get rid of this issue by adding org.jboss.xnio/xnio-api {:mvn/version "3.8.16.Final"} org.jboss.xnio/xnio-nio {:mvn/version "3.8.16.Final"} to my deps.edn file. Eventually, I succeeded and got a REPL working, but there were a few additional classes that threw errors when I invoked the (go) function at the REPL: those erors were fixed by adding the below to the deps.edn file: org.wildfly.common/wildfly-common {:mvn/version "2.0.0"} org.jboss.logging/jboss-logging {:mvn/version "3.6.0.Final"} io.smallrye.config/smallrye-config-common {:mvn/version "3.8.3"} io.smallrye.common/smallrye-common-net {:mvn/version "2.4.0"} org.jboss.threads/jboss-threads {:mvn/version "3.6.1.Final"} io.smallrye.common/smallrye-common-cpu {:mvn/version "2.4.0"} Set-up on Guix System: - openjdk 21.0.2 (also tested: openjdk 11.0.22) - clojure-tools 1.11.2.1446 Note that I can run the above on Debian 12.6 just as the documentation suggests, with no need to add any additional classes to the deps.edn file when I have clojure-tools manually installed on Debian per the script on the Clojure website. Additionally, I got the same errors when I used clojure-tools on Debian using the Guix package manager. This suggests that the issue is related to clojure-tools. I have a work-around so this issue is in no way critical. Nevertheless, I thought that I should report it should the folks that look after the clojure-tools package want to look into it. I don't know my way around the Clojure web stack so I couldn't figure out how to provide a simpler example. I will try to find something simpler in a different domain in the meantime. Regards, afm
