it happened again. when i've added the :mvn/local-repo "m2" to my deps.edn and ran time clj -e 1 for the 1st time, i've only seen some of the dependencies being printed, while it was actually downloading all of them:

Downloading: ring/ring-jetty-adapter/1.6.3/ring-jetty-adapter-1.6.3.pom from 
Downloading: crypto-equality/crypto-equality/1.0.0/crypto-equality-1.0.0.jar from

raven:reap onetom$ du -hsc m2
22M     m2
22M     total

after an rm -r m2, on subsequent run, i could see all of the deps printed as they were being downloaded and the size of the maven cache ended up being the same:

raven:reap onetom$ rm -r m2
raven:reap onetom$ time clj -Sforce -e 1

22M     total

for the record, my deps.edn looks like this:

{:paths     ["src" "rsc" "java" "classes"]
 :deps      {org.clojure/clojure                    {:mvn/version "1.10.1"}

                    :extra-deps  {
                                  ;clj-http-fake {:mvn/version "1.0.3"}
                                  }}}
 :mvn/local-repo "m2"
 ; 
 :mvn/repos {"central" {:url

                        #_""}
             "clojars" {:url ""}}}

and my clj version info looks like this:

raven:reap onetom$ time clj -Sverbose -e 1
version      = 1.10.1.469
install_dir  = /nix/store/bqs5l2mc2jlj5z1a21ix0sz0ak8cvn0l-clojure-1.10.1.469-prefix

config_paths = /nix/store/bqs5l2mc2jlj5z1a21ix0sz0ak8cvn0l-clojure-1.10.1.469-prefix/deps.edn /Users/onetom/.clojure/deps.edn deps.edn
cache_dir    = .cpcache
cp_file      = .cpcache/1871601414.cp

/Users/onetom/.clojure/deps.edn is all commented out

Is it possible to just download the dependencies of my project, without running anything? Like with lein deps.

Doing -Spath will print the classpath, and won't execute anything.

Nice trick, thanks!
