Here is <code>modules/a/deps.edn</code></p> <pre><code>{:paths ["src"]} </code></pre> <p>Those files require a compilation step. Here is the top-level <code>build.clj</code> file expected to proccess those files.</p> <pre><code>(ns build (:require [clojure.tools.build.api :as b])) (def module-a (binding [b/*project-root* "modules/a"] (b/create-basis {:project "deps.edn"}))) (defn compile-a [_] (b/compile-clj {:basis module-a :src-dirs ["modules/a/src"] :class-dir "target/module-a/classes"})) </code></pre> <p>However when invoking <code>clojure -T:build compile-a</code> from top-level directory I encounter the following error </p> <pre><code>Execution error (FileNotFoundException) at user/eval136$fn (compile.clj:5). Could not locate monorepo/module/a__init.class, monorepo/module/a.clj or monorepo/module/a.cljc on classpath. </code></pre> <p>The problem is that the "src" relative directory is not expanded in the <code>:classpath-roots</code> which lead <code>compile-clj</code> to search source files in the wrong location. It is possible to work around the issue by binding the <code>*project-root*</code> again and adapting <code>:src-dirs</code> and <code>class-dir</code> relative to module A root directory like this</p> <pre><code>(defn compile-a [_] (binding [b/*project-root* "modules/a"] (b/compile-clj {:basis module-a :src-dirs ["src"] :class-dir "../../target/module-a/classes"}))) </code></pre> <p>However IMO it would be better if the computed classpath in the basis was fully expanded by transforming relative paths into absolute ones to avoid this extra ceremony.</p> <p>What do you think?<br> Is there a reason why relative source path directories are currently kept relative ?</p> tools.build https://ask.clojure.org/index.php/11982/relative-directories-in-classpath-roots Sun, 19 Jun 2022 16:50:53 +0000 https://ask.clojure.org/index.php/11922/how-to-require-a-symbol-from-within-a-function <p>Why can't I use require in a function like so?</p> <pre><code>(comment (-&gt;&gt; [1 2] (reduce (fn [acc v] (require '[clojure.set :as c-set]) (c-set/union acc #{v})) #{})) ;=&gt; Syntax error compiling at (lab/sandbox_playground.clj:31:18). ; No such namespace: c-set ) </code></pre> <p>At first I was thinking it was that require needs to go top-level.

Lein provided injections as an escape hatch, tools.build doesn't seem to have an equivalent.</p> <p>Looking at the code, tools.build seems to compile code from a separate generated script in a temp file, which seems to make injections or wrappers impossible. Also couldn't find options to pass other than compiler options.</p> <p>A more in-depth description of this use case can be found on clojureverse: <a rel="nofollow" href="https://clojureverse.org/t/require-import-inside-deftest/8644/3">https://clojureverse.org/t/require-import-inside-deftest/8644/3</a></p> <p>Is there a solution or suggested workaround available?</p> tools.build https://ask.clojure.org/index.php/11610/is-it-possible-to-set-a-var-during-compilation-in-tools-build Mon, 28 Feb 2022 20:50:43 +0000
