A Leiningen plugin for testing against multiple versions of Clojure at once.

lein-multi

lein-multi is a Leiningen plugin for running tasks against multiple dependency sets. Most notably, it allows you to test your project against multiple versions of Clojure.

NOTE: This plugin has been superseded by Leiningen 2.x's profiles.

Usage

Syntax:

$ lein multi <task> [--with <set name>] [args]

Specify dependency sets in your project.clj:

:multi-deps {"1.1" [[org.clojure/clojure "1.1.0"]
                    [ring/ring-core "0.2.2"]]
             "1.2" [[org.clojure/clojure "1.2.0"]
                    [ring/ring-core "0.3.0-beta1"]]
             :all  [[compojure "0.6.4"]]}

Download these dependencies with lein multi deps (or by running your tests with lein multi test). They will be placed in the folder specified by :multi-library-path (default: multi-lib).

Dependencies included in the :all set will be included with all other sets, including the base set specified in the :dependencies keyword in root of your project.clj.

Run a task against a single dependency set from :multi-deps using the --with option followed by the set name as specified in your project.clj.

lein-multi will accept and run other tasks, though the result may not be what you expect. Tasks that do not require a project (currently new, help, and version) are run as normal.

Additionally, other tasks may require special handling that isn't yet implemented. For example, lein multi uberjar will only create one jar.

Installation

lein plugin install lein-multi 1.1.0

TODO

  • Special handling for pom, jar, uberjar, and clean
  • Final test summary for all sets
