Heroku buildpack for clojure tools

Minimal unofficial buildpack for clojure tools.deps and tools.build projects. Based off the official heroku clojure build pack.

To use this build pack

Set your heroku app to use this build pack:

heroku buildpacks:set https://github.com/andersmurphy/heroku-buildpack-clojure-tools.git -a my-app

Make sure your project root contains the following files:

A Procfile file:

web: java -jar target/my-app.jar -m my-app.app

A bin/build file (make this file executable with chmod +x bin/build):

clojure -T:build uber

A deps.edn file:

{:paths   ["src" "resources"]
 :deps    {org.clojure/clojure {:mvn/version "1.11.0-alpha3"}}
 :aliases {:build
           {:deps       {io.github.clojure/tools.build {:git/tag "v0.6.8"
                                                        :git/sha
                                                        "d79ae84"}}
            :ns-default build}}}

A build.clj file:

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

(def lib 'my-app)
(def class-dir "target/classes")
(def basis (b/create-basis {:project "deps.edn"}))
(def uber-file (format "target/%s.jar" (name lib)))

(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 :src-dirs ["src"] :class-dir class-dir})
  (b/uber {:class-dir class-dir
           :uber-file uber-file
           :basis     basis
           :main      'my-app.app}))
