[Mea Culpa I pointed to Clojure 1.3, not Clojure 1.3.0.]
I just downloaded the latest Clojure jar file, 1.3.0. I have a simple cake project, which is now throwing a missing artifact error
1 required artifact is missing.
for artifact:
org.apache.maven:super-pom:jar:2.0
What do I need to add to my project.clj file
(defproject repl-test "0.0.1-SNAPSHOT"
:description "TODO: add summary of your project"
:dependencies [[org.clojure/clojure "1.3"]
[org.clojure/clojure-contrib "1.2.0"]
[clojure-csv/clojure-csv "1.2.4"]
[org.clojure/tools.cli "0.1.0"]
[clj-http "0.1.3"]]
:repositories {"clojure-snapshots" "http://build.clojure.org/snapshots"}
:main repl-test)
or what do I need to build to fetch this missing artifact?
I have made sure the clojure-1.3.0.jar file is installed.
If this is a POM problem, I'm not sure what command to run to install the artifact.
Replace [org.clojure/clojure "1.3"] with [org.clojure/clojure "1.3.0"] then this should work.

Okay. I'm trying to muck about with twitter4j inside a Clojure REPL, provided by Leiningen. I've specified twitter4j as a build dependency:
(defproject testproject "0.1.0-SNAPSHOT"
:description "Tryin stuff"
:repositories {
"twitter4j" "http://twitter4j.org/maven2"
}
:dependencies [[org.clojure/clojure "1.5.1"]
[compojure "1.1.6"]
[org.twitter4j/twitter4j-core "3.0.5"]
[org.twitter4j/twitter4j-stream "3.0.5"]]
:plugins [[lein-ring "0.8.8"]]
:ring {:handler testproject.core/app}
:profiles {:dev
{:dependencies [[javax.servlet/servlet-api "2.5"]
[ring-mock "0.1.5"]]}})
So far, so good. lein deps downloads everything without complaint into the default repo in ~/.m2. Awesome. I fire up the REPL, and I get this and only this:
user=> (import '(org.twitter4j.conf ConfigurationBuilder))
ClassNotFoundException org.twitter4j.conf.ConfigurationBuilder java.net.URLClassLoader$1.run (URLClassLoader.java:202)
The twitter4j jars are all present and accounted for, in ~/.m2/org/twitter4j/twitter4j-core/3.0.5/. Is there... something I don't get about importing Java classes? Some extra config I need to provide?
Try this (the proper package name):
user=> (import '(twitter4j.conf ConfigurationBuilder))
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:

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.
I'm new to clojure. I have a jar file I want to play with in a clojure repl, but I've failed to do so with leiningen 2.
I have tried placing the jar file in src/myjar.jar and also in src/org/mydomain/myjar.jar
When I run lein repl I get errors stating that leiningen can not find my artifact, and a reference to a page about repeatability which I do not understand.
Here is my project.clj (with the real name of myjar)
(defproject cljliveordead "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 "1.3.0"]
[org.allen.temporalintervalrelationships/time "0.2" :extension "jar"]])
You can use local jars using the lein-localrepo plugin. Add this line to your project.clj
:plugins [[lein-localrepo "0.4.0"]]
Then install the jar to the local repository using
lein localrepo install <path-to-jar> org.allen.temporalintervalrelationships/time 0.2
You can check that the file is installed by running lein localrepo list and check that lein can resolve the project dependencies using lein deps. If all is well then you can start playing with the jar using lein repl.
Leiningen doesn't like local jars due to its goal of repeatable builds. If this was a real project using a third party closed source jar then the best thing to do is install it in a local Nexus repository and add a reference to that repository to your project.
However, this all seems a bit heavyweight for what you are trying to achieve. If all you want to do is play with the jar in the REPL then create a simple project like this
(defproject clojure-time "0.1.0-SNAPSHOT"
:dependencies [[org.clojure/clojure "1.4.0"]
[com.cemerick/pomegranate "0.0.13"]])
and use the pomegranate library to add the jar to your classpath manually
(require '[cemerick.pomegranate :as p])
(p/add-classpath "jsr-310-ri-0.6.3.jar")
(javax.time.Instant/now)
and play away.
the hackish way is to just put it into /proiject/path/lib/ and the 'proper' way is to:
add a dependency for it to your project
run lein deps which will print the command for installing the jar to your local maven repo
run the command leiningen gives you with the path to your jar
run lein deps again
I use clojure-csv in a lot of my applications, so make sure the modules referencing clojure-csv were able to build with it, this is what I did:
0) Ran lein new bene-csv
1) Added this to project.clj (after enter lein new bene-csv). The pertinent line is [clojure-csv/clojure-csv "1.3.2"], but it makes sense to show you the whole project.clj for good example's sake.
(defproject bene-csv "1.0.4-SNAPSHOT"
:description "A csv parsing library"
:dependencies [[org.clojure/clojure "1.3.0"]
[clojure-csv/clojure-csv "1.3.2"]
[util "1.0.2-SNAPSHOT"]]
:aot [bene-csv.core]
:omit-source true)
2) Made sure my bene-csv/src/bene_csv/core.clj references clojure-csv.
(ns bene-csv.core
^{:author "Charles M. Norton",
:doc "bene-csv is a small library to parse a .csv file.
Created on March 8, 2012"}
(:require [clojure.string :as cstr])
(:require [util.core :as utl])
(:use clojure-csv.core))
Finally, I ran these commands, so that my main project could reference bene-csv's functions and defs.
lein deps
lein install
I have a Clojure "main" application that depends on several Clojure libraries, two of which are mine. The compile phase, whether just compiling or running uberjar takes a long time. It's on the order of at least one minute or more. Neither of my libraries nor main are very large.
My libraries' and main project.clj files contain
:aot [bene-cmp.core]
:omit-source true
directives.
What can I do, if anything, to speed up the build process?
Here are the three project.clj files.
project.clj main

(defproject bene-cmp "1.0.0-SNAPSHOT"
:description "This is the main benetrak/GIC comparison program."

Here's my project.clj:
(defproject hello-world "1.0.0-SNAPSHOT"
:description "FIXME: write description"
:dependencies [[org.clojure/clojure "1.3.0"]]
:dev-dependencies [[swank-clojure "1.5.0-SNAPSHOT"]]
:plugins [[lein-swank "1.4.3"]])
Leiningen downloads swank-clojure 1.4.0 every time I run lein swank.
(I'm using leiningen 1.7.0)
I don't think you need both the :plugins swank and the :dev-dependencies one.
try with just the dev-dependencies
Assuming you want to always use the same version of swank-clojure (which is also lein-swank),
you can run (for leiningen 1.x):
lein plugin install swank-clojure "1.5.0-SNAPSHOT"
For leiningen 2.x you can add the following to :plugins in the profile.clj file of your lein directory:
[lein-swank "1.5.0-SNAPSHOT"]
and the plugin will be usable from all of your leiningen projects without having to specify the requirement in the project file.
