Clojurians Log v2

Hi.When building my tiny test project I get: $ cd <PROJECT-ROOT> $ clj -T:build uber Namespace could not be found on classpath: build I did everything according to: https://clojure.org/guides/tools_build

Hang on.... I ENTER-ed too early.... Sry!

My dep.edn is:

{:paths ["src"]
 :deps {org/jaudiotagger {:mvn/version "2.0.3"}
        claudio/claudio {:mvn/version "0.1.3"}}
 :aliases
 {;; Run with clj -T:build function-in-build
  :build {:deps {io.github.clojure/tools.build {:git/tag "v0.10.11" :git/sha "c6c670a"}} 
          :ns-default build
          }}}

(It's "deps.edn" actually...)

The build.clj resides directly in src:

(ns build
  (:require [clojure.tools.build.api :as b]))

(def lib 'audio-tagger)
(def version (format "0.1.%s" (b/git-count-revs nil)))
(def class-dir "target/classes")
(def uber-file (format "target/%s-%s-standalone.jar" (name lib) version))

;; delay to defer side effects (artifact downloads)
(def basis (delay (b/create-basis {:project "deps.edn"})))

(defn clean [_]
  (b/delete {:path "target"}))

(defn uber [_]
  (clean nil)
  (b/copy-dir {:src-dirs ["src" "resources"]
               :target-dir class-dir})
  (b/compile-clj {:basis @basis
                  :ns-compile '[audio-tagger]
                  :class-dir class-dir})
  (b/uber {:class-dir class-dir
           :uber-file uber-file
           :basis @basis
           :main 'audio-tagger.main}))

There is a main in src/audio_tagger.clj:

(defn -main [& args]
  (if (seq args)
    (doseq [arg args]
      (println arg))
    (throw (Exception. "Must have at least one argument!"))))

I spend all day to compile these 5 lines. In my frustration I finally came here to beg for some pros hints.

When using -T the project paths are not on the classpath (but by default “.” Is)

So you can put it in the project root or add :paths [“src”] to your :build alias

Sry about the German snippets...

I think I get a clue on your hint "you can put it in the project root". You speak of build.clj? That can be moved from src to <PROJECT-ROOT>? I'll try it. Already MANY THANKS for having a look at this misery.

Unfortunately same result as above.

Okay, I just learned here: https://kozieiev.com/blog/packaging-clojure-into-jar-uberjar-with-tools-build/ that build.clj MUST reside in project root, it seems. The rest is identlical to the official guide. Alas, I still get:

$ cd <PROJECT-ROOT>
$ clj -T:build uber
fatal: not a git repository (or any parent up to mount point /)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).

I just init-ed a git repos with my project root and commit that crap. Now it runs. uberjar got created. Honestly...... !!!!???!!! I'missing words.... Shouldn't the fact be mentioned in the official guide that tools.deps ONLY FLIES when GIT is involved and you have at least one commit. And what does a repos system have to to with a build system anayway??? I'm puzzled...
