hi! I'm somehow getting a nullpointerexception when trying to set this up. I have the following in ~/.clojure/deps.edn :

:aliases {:rebel {:extra-deps {com.bhauman/rebel-readline {:mvn/version "0.1.4"}}
                    :main-opts ["-m" "rebel-readline.main"]}
            :new {:extra-deps {com.github.seancorfield/clj-new 
                               {:mvn/version "1.1.297"}}
                  :exec-fn clj-new/create
                  :exec-args {:template "app"}}}

heyarne08:04:32

and running clojure -X:new :name myname/myapp gives me this stacktrace:

{:clojure.main/message
 "Execution error (NullPointerException) at clj-exec/requiring-resolve' (clj_exec.clj:57).\nnull\n",

Any idea what's happening?

seancorfield17:04:52

@arne-clojurians Are you running that command in a directory that has a deps.edn file? Maybe that has a :new alias that is hiding your user-level one?

seancorfield17:04:43

Also, what does clojure -Sdescribe say?

heyarne16:05:12

@U04V70XH6 thanks for your response! the error happens in different directories, none of which has a deps.edn, so the shadowing doesn't happen.

heyarne16:05:27

clojure -Sdescribe looks like this:

{:version "1.10.1.645"
 :config-files ["/nix/store/1j1rbh1yy66rmpf1lqfsafni06k7bvid-clojure-1.10.1.645/deps.edn" "/home/arne/.clojure/deps.edn" ]
 :config-user "/home/arne/.clojure/deps.edn"
 :config-project "deps.edn"
 :install-dir "/nix/store/1j1rbh1yy66rmpf1lqfsafni06k7bvid-clojure-1.10.1.645"
 :config-dir "/home/arne/.clojure"
 :cache-dir "/home/arne/.clojure/.cpcache"
 :force false
 :repro false
 :resolve-aliases ""
 :classpath-aliases ""
 :jvm-aliases ""
 :main-aliases ""
 :tool-aliases ""
 :all-aliases ""}

heyarne16:05:18

and (last (:config-files %)) / (:config-user %) is the correct config file

heyarne16:05:38

the other deps.edn in /nix/store/… is the vanilla deps.edn:

{
  :paths ["src"]

  :deps {
    org.clojure/clojure {:mvn/version "1.10.1"}
  }

  :aliases {
    :deps {:extra-deps {org.clojure/tools.deps.alpha {:mvn/version "0.9.763"}}}
    :test {:extra-paths ["test"]}
  }

  :mvn/repos {
    "central" {:url ""}
    "clojars" {:url ""}
  }
}

seancorfield16:05:12

1.10.1.645 is pretty old — a lot has changed since then — and that isn’t even a stable release: https://clojure.org/releases/tools

seancorfield16:05:06

clj-new’s README states 1.10.1.727 as a minimum version.

seancorfield16:05:26

LMK if you still see the error on an up-to-date Clojure CLI.

heyarne18:05:38

Indeed! I updated to 1.10.3.x and it works flawlessly. Thanks 🙂
