I am using the praticelli aliases which has this for deps-new: :project/new {:replace-deps {com.github.seancorfield/clj-new {:mvn/version "1.1.331"}} :exec-fn clj-new/create :exec-args {:template lib :name practicalli/playground} :main-opts ["-m" "clj-new.create"]} I have a hard time using it.... The options for creating from a custom template are not clear to me, after reading documentation.

Asking it for the option is confusing:

clj  -A:project/new -h

it tells me this in first line: WARNING: Use of -A with clojure.main is deprecated, use -M instead Usage: clojure -X:project/add clj-new/create :template template-name :name project-name options

First I get a warning, and the it tells me for usage "clojure -X:project/add clj-new/create", which I did not type. Is this a side effect of the alias ?

But even typing the right thing, does give a very confusing error:

clojure -X:project/add clj-new/create :template clj-py-r-template/clj-template  :name me/my-app

Failed with: Failed to resolve version for clj-py-r-template:lein-template.clj-template:jar:RELEASE: Could not find metadata clj-py-r-template:lein-template.clj-template/maven-metadata.xml in local (/home/carsten/.m2/repository)

For more detail, enable verbose logging with :verbose 1, 2, or 3

I am digging...

My maven folder of the template contains basically empty folders only, no jar or whatever.

So it could not find the thing in clojars, I suppose. But it is there: https://clojars.org/clj-py-r-template/clj-template

anu idea what could be wrong ?

it worked for sure some time ago, with older versions of clj-new, maybe a year ago

I figured it ou after a while: This works:

clojure -X:project/new clj-new/create :template clj-py-r-template  :name me/my-app

so without the "/clj-template" suffix in the template name

@seancorfield I did a PR to clarify the documentation: https://github.com/seancorfield/clj-new/pull/77

@carsten.behring Note that is clj-new not deps-new -- the former can process Leiningen and Boot template whereas the latter does not: it is deps.edn specific and uses a declarative form of template. I accepted your PR (thank you!) and have done some additional editing to clarify how qualified template names work (including linking to Leiningen's page about templates).

Thanks for this

Would it make sense to add (def clean bb/clean) to the build.clj created by deps-new? Similarly have a jar and uber function that just turns around and calls the bb version? That way there'd be a minimally useful build.clj.

@dorab In addition to the test and ci tasks they already have you mean?

(ns build
  (:refer-clojure :exclude [test])
  (:require [org.corfield.build :as bb]))

(def lib 'app/app)
(def version "0.1.0-SNAPSHOT")
(def main ')

(defn test "Run the tests." [opts]
  (bb/run-tests opts))

(defn ci "Run the CI pipeline of tests (and build the uberjar)." [opts]
  (-> opts
      (assoc :lib lib :version version :main main)
      (bb/run-tests)
      (bb/clean)
      (bb/uber)))

The idea is to encourage folks to always run tests before building the JAR -- and this way if the tests fail, your JAR doesn't get built (and target doesn't get deleted from any prior run).

Yes, in addition to the ci and test that are already there.

I'd rather not encourage building a JAR without running the tests...

I was surprised when I tried to run clj -T:build clean in a directory that was newly created by deps-new. I would expect that deps-new created a minimally functioning build.clj - meaning that it could run the following tasks clean, jar, test, and uber (for apps).

If a project is newly created, you wouldn't need to run clean. The ci task calls clean prior to calling jar or uber.

Having test and ci is "minimally functioning".

Okay. I get what you're saying. The model I had in my head was that the build.clj created by deps-new would have all the basic functionality (like a Makefile). If I wanted something different, I was of course able to modify it as I wished - but that there would be an example of how the "standard" tasks were defined. Perhaps a different approach might be to have the basic clean and jar tasks in the , but commented out. So, that someone could uncomment them as needed.

Look at https://github.com/seancorfield/next-jdbc/blob/develop/build.clj and https://github.com/seancorfield/honeysql/blob/develop/build.clj and https://github.com/clojure-expectations/clojure-test/blob/develop/build.clj -- real-world projects that have just "run tests", ci, and deploy (which a fresh lib project from deps-new has -- the app project doesn't have/need deploy).

If someone wants to add direct clean and/or jar tasks to

(ns build
  (:refer-clojure :exclude [test])
  (:require [clojure.tools.build.api :as b] ; for b/git-count-revs
            [org.corfield.build :as bb]))

(def lib 'lib/lib)
(def version "0.1.0-SNAPSHOT")
#_ ; alternatively, use MAJOR.MINOR.COMMITS:
(def version (format "1.0.%s" (b/git-count-revs nil)))

(defn test "Run the tests." [opts]
  (bb/run-tests opts))

(defn ci "Run the CI pipeline of tests (and build the JAR)." [opts]
  (-> opts
      (assoc :lib lib :version version)
      (bb/run-tests)
      (bb/clean)
      (bb/jar)))

(defn deploy "Deploy the JAR to Clojars." [opts]
  (-> opts
      (assoc :lib lib :version version)
      (bb/deploy)))

But I would discourage that approach and so I don't want them in the build.clj file out of the box.

Okay. That works for me.
