How do I add non Maven code into boot-clj/boot?

Question

I worked through Developing Clojure on App Engine. I was then attempting to replicate the same functionality using boot. However, I do not know how to include the Google App Engine (non Maven) code in a boot project. Any help getting me past this point is appreciated.

All of the following code is hosted here

Here is the currently working project.clj

(defproject clojure-gae "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :license {:name "Eclipse Public License"
            :url "http://www.eclipse.org/legal/epl-v10.html"}
  :dependencies [[org.clojure/clojure "1.7.0"]
                 [ring "1.4.0-RC2"]
                 [compojure "1.3.4"]
                 [com.google.appengine/appengine-api-1.0-sdk "1.9.31"]]
  :plugins [[lein-ring "0.9.6" :exclusions [org.clojure/clojure]]]
  :ring {:handler clojure-gae.core/app}
  :profiles {:dev
             {:dependencies
              [[com.google.appengine/appengine-api-stubs "1.9.31"]
               [com.google.appengine/appengine-local-runtime "1.9.31"]
               [com.google.appengine/appengine-local-runtime-shared "1.9.31"]]}})

Here is the currently broken build.boot I am working on, based on the previous project.clj.

(set-env!
 :source-paths #{"src"}
 :resource-paths #{"assets"}
 :dependencies '[[compojure "1.3.4"]
                 [com.google.appengine/appengine-api-stubs "1.9.31"]
                 [com.google.appengine/appengine-local-runtime "1.9.31"]
                 [com.google.appengine/appengine-local-runtime-shared "1.9.31"]
                 [org.clojure/clojure "1.7.0"]
                 [pandeiro/boot-http "0.7.1-SNAPSHOT" :scope "test"]
                 [ring "1.4.0-RC2"]])

(require
 '[pandeiro.boot-http :refer :all])

(task-options!
 pom {:project "clojure-gae"
      :version "0.1"}
 jar {:main 'clojure_gae.core
      :manifest {"Description" "A Clojure Application on Google App Engine"}}
 repl {:init-ns 'clojure-gae.core}
 serve {:handler 'clojure-gae.core/app
        :reload true})

(def DEV_DEPENDENCIES '[])

(deftask dev
  "Profile for doing local development"
  []
  (set-env! :dependencies #(reduce conj % DEV_DEPENDENCIES))
  (comp
   (serve)))

It fails with

bash$ boot dev

Obviously, boot has no idea how to get the com.google.appengine code. In lein's world, there was the lein localrepo install ... steps I went through (in the article) concerning how to install non Maven projects into my local repository. It seems that the App Engine Jar's should still be in my local repository, but boot does not seem to see them. How do I make the appengine jars visible within my boot project?

Answer 1

The jar has to be visible from your classpath. This is similar to this question : leiningen - how to add dependencies for local jars?

But for boot, so adding the location to your line :resource-paths #{"assets"} should work.

For instance, if your jars are in "lib", the previous line should look like this : :resource-paths #{"assets" "lib"}

Note : in your case, installing these with lein localrepo should still work. But boot has a built-in install task https://github.com/boot-clj/boot/blob/master/boot/core/src/boot/task/built_in.clj#L679

To use from the command-line like that : boot install -f warp-0.1.0.jar -p tailrecursion/warp"
