Starting from:
lein new foo
cd foo
Say I have a random JAR file that is not available in any repository:
touch README.md
jar cf bar.jar README.md
Let's assume I've installed it in a project-local repository like this:
mkdir repo
mvn install:install-file -DgroupId=local -DartifactId=bar \
-Dversion=1.0.0 -Dpackaging=jar -Dfile=bar.jar \
-DlocalRepositoryPath=repo
And I write my project.clj like this:
(defproject foo "0.1.0-SNAPSHOT"
:dependencies [[org.clojure/clojure "1.4.0"]
[local/bar "1.0.0"]]
:repositories {"project" "file:repo"})
Making sure my local cache is clean:
$ rm -rf ~/.m2/repository/local
The first time, Leiningen prints errors:
$ lein deps
Could not find artifact local:bar:pom:1.0.0 in central (http://repo1.maven.org/maven2)
Could not find artifact local:bar:pom:1.0.0 in clojars (http://clojars.org/repo/)

But the second time it works:
$ lein deps
$
Some inspection shows that local/bar has been copied to my ~/.m2/repository cache:
$ find ~/.m2/repository/local
~/.m2/repository/local
~/.m2/repository/local/bar
~/.m2/repository/local/bar/1.0.0
~/.m2/repository/local/bar/1.0.0/_maven.repositories
~/.m2/repository/local/bar/1.0.0/bar-1.0.0.jar
~/.m2/repository/local/bar/1.0.0/bar-1.0.0.pom
Starting from scratch:
$ rm -rf ~/.m2/repository/local
Try running Leiningen:
$ lein deps

Could not find artifact local:bar:pom:1.0.0 in clojars (https://clojars.org/repo/)

Failed to collect dependencies for [#<Dependency org.clojure:clojure:jar:1.4.0 (compile)> #<Dependency local:bar:jar:1.0.0 (compile)>]
No matter how many times I run it, I get the same results. My ~/.m2/repository cache has the correct directories, but no files have been copied:
$ find ~/.m2/repository/local
~/.m2/repository/local
~/.m2/repository/local/bar
~/.m2/repository/local/bar/1.0.0
Variations on the repository URL like file://repo have no positive effect.
