Takes deps.edn and packs an uberjar out of it.

• Fast: Does not unpack intermediate jars on disk.
• Explicit: Prints dependency tree. Realize how much crap you’re packing.
• Standalone: does not depend on current classpath, does not need live Clojure environment.
• Embeddable and configurable: fine-tune your build by combining config options and calling specific steps from your code.

Add to your bash aliases:

clj -Sdeps '{:deps {uberdeps {:mvn/version "0.1.3"}}}' -m uberdeps.uberjar

Or add to your deps.edn or ~/.clojure/deps.edn:

:aliases {
  :uberjar {:extra-deps {uberdeps {:mvn/version "0.1.3"}}
            :main-opts ["-m" "uberdeps.uberjar"]}}
}

Supported command-line options are:

--deps-file <file>                Which deps.edn file to use to build classpath. Defaults to 'deps.edn'
--aliases <alias:alias:...>       Colon-separated list of alias names to include from deps file. Defaults to nothing
--target <file>                   Jar file to ouput to. Defaults to 'target/<directory-name>.jar'
--level (debug|info|warn|error)   Verbose level. Defaults to debug

(require '[uberdeps.api :as uberdeps])

(let [exclusions (into uberdeps/exclusions [#"\.DS_Store" #".*\.cljs" #"cljsjs/.*"])
      deps       (clojure.edn/read-string (slurp "deps.edn"))]
  (binding [uberdeps/exclusions exclusions
            uberdeps/level      :warn]
    (uberdeps/package deps "target/uber.jar" {:aliases #{:uberjar}})))

If your project has a -main function, you can run it from within the generated uberjar:

java -cp target/<your project>.jar clojure.main -m <your namespace with main>

• Fixed NPE when target is located in current dir #7

• Make target dirs if don’t exist #4

• Normalize dependencies without namespaces #3

• Initial version
