How to use current builds of rxjava in clojure with leiningen

I want to use some of the latest features being built frequently at https://github.com/Netflix/RxJava in Clojure, but am having some difficulties getting Leiningen to reference the local .jar that I build. The last version of rxjava released to Clojars was 0.9.0, which I can successfully reach with the following in my projects.clj

:dependencies [[org.clojure/clojure               "1.5.1"]
             [com.netflix.rxjava/rxjava-clojure "0.9.0"]]

Now, I do a successful build of the current rxjava sources, which produces the following files

/Users/rebcabin/Documents/RxJava/language-adaptors/rxjava-clojure/build/libs/rxjava-clojure-0.9.1-SNAPSHOT-javadoc.jar
/Users/rebcabin/Documents/RxJava/language-adaptors/rxjava-clojure/build/libs/rxjava-clojure-0.9.1-SNAPSHOT-sources.jar
/Users/rebcabin/Documents/RxJava/language-adaptors/rxjava-clojure/build/libs/rxjava-clojure-0.9.1-SNAPSHOT.jar

In my Clojure project directory, I do the following

mvn deploy:deploy-file \
    -DgroupId=local \
    -DartifactId=rxjava-clojure \
    -Dversion=0.9.1-SNAPSHOT \
    -Dpackaging=jar \
    -Dfile=/Users/rebcabin/Documents/RxJava/language-adaptors/rxjava-clojure/build/libs/rxjava-clojure-0.9.1-SNAPSHOT.jar \
    -Durl=file:maven_repository

following the instructions given here: https://gist.github.com/stuartsierra/3062743 (see the bottom) via http://www.pgrs.net/2011/10/30/using-local-jars-with-leiningen/ and leiningen - how to add dependencies for local jars?.

That reports success and produces the following:

$ find maven_repository/
maven_repository/
maven_repository//local
maven_repository//local/rxjava-clojure
maven_repository//local/rxjava-clojure/0.9.1-SNAPSHOT
maven_repository//local/rxjava-clojure/0.9.1-SNAPSHOT/maven-metadata.xml
maven_repository//local/rxjava-clojure/0.9.1-SNAPSHOT/maven-metadata.xml.md5
maven_repository//local/rxjava-clojure/0.9.1-SNAPSHOT/maven-metadata.xml.sha1
maven_repository//local/rxjava-clojure/0.9.1-SNAPSHOT/rxjava-clojure-0.9.1-20130628.172154-1.jar
maven_repository//local/rxjava-clojure/0.9.1-SNAPSHOT/rxjava-clojure-0.9.1-20130628.172154-1.jar.md5
maven_repository//local/rxjava-clojure/0.9.1-SNAPSHOT/rxjava-clojure-0.9.1-20130628.172154-1.jar.sha1
maven_repository//local/rxjava-clojure/0.9.1-SNAPSHOT/rxjava-clojure-0.9.1-20130628.172154-1.pom
maven_repository//local/rxjava-clojure/0.9.1-SNAPSHOT/rxjava-clojure-0.9.1-20130628.172154-1.pom.md5
maven_repository//local/rxjava-clojure/0.9.1-SNAPSHOT/rxjava-clojure-0.9.1-20130628.172154-1.pom.sha1
maven_repository//local/rxjava-clojure/maven-metadata.xml
maven_repository//local/rxjava-clojure/maven-metadata.xml.md5
maven_repository//local/rxjava-clojure/maven-metadata.xml.sha1

I now fix my projects.clj file to contain the following:

:dependencies [[org.clojure/clojure               "1.5.1"]
             [com.netflix.rxjava/rxjava-clojure "0.9.1"]]
:repositories {"local" ~(str (.toURI (java.io.File. "maven_repository")))}

but lein deps fails to find the local repo

$ lein deps
Could not find artifact com.netflix.rxjava:rxjava-clojure:jar:0.9.1 in central (http://repo1.maven.org/maven2/)
Could not find artifact com.netflix.rxjava:rxjava-clojure:jar:0.9.1 in clojars (https://clojars.org/repo/)
Could not find artifact com.netflix.rxjava:rxjava-clojure:jar:0.9.1 in local (file:/Users/rebcabin/Documents/ClojureProjects/rxjava/expt1/maven_repository/)
This could be due to a typo in :dependencies or network issues.

The following guesses in project.clj also do not work:

:dependencies [[org.clojure/clojure               "1.5.1"]
             [com.netflix.rxjava/rxjava-clojure "0.9.1-SNAPSHOT"]]
:repositories {"local" ~(str (.toURI (java.io.File. "maven_repository")))}

:dependencies [[org.clojure/clojure               "1.5.1"]
             [com.netflix.rxjava/rxjava-clojure "0.9.1--20130628.172154-1"]]
:repositories {"local" ~(str (.toURI (java.io.File. "maven_repository")))}

any ideas how to proceed, please & thanks?

(I also answered on the mailing list where you asked this)

The groupId in your deploy-file command is incorrect. It should be com.netflix.rxjava. Then in your project.clj, use [com.netflix.rxjava/rxjava-clojure "0.9.1-SNAPSHOT"] for your dependency. Also note that you'll need to do the same with rxjava.core.

from the rxjava project directory run

mvn install

to install the jars to your system's local maven repo.
from your Clojure project's directory add 0.9.1-SNAPSHOT as a dependency and then

lein deps :tree

and make sure you see the correct version used.
