如何使用leiningen的maven插件

Question

The specific plugin I want to be able to use is the jruby-maven-plugin so I can easily use compass in a clojure project.

If it's not possible to use maven plugins, what would be the best strategy to use a ruby gem in a clojure project?

Answer 1

The following two projects provide ruby gem support. lein-ruby clogems

clogems project does not have anything in the way of documentation, so you are probably on your own with that.

lein-ruby provides some documentation on it's github page. From the github page for lein-ruby.

Usage

Tasks

This plugin adds one task to Leiningen:

• lein ruby CMD [ARGS...] - runs a Ruby command

You are responsible for adding the desired version of jruby-complete to your project's dependencies.

Hooks

The plugin also includes a set of hooks (in the leiningen.ruby.bundler namespace) which accomplish three things:

• augment lein deps to install bundler and any gems specified in your project's Gemfile into vendor/gems

• add vendor/gems to your project's classpath

• package the gems in vendor/gems as part of your project's jar

Options

lein-ruby also introduces two options which can be set in your project.clj:

• :ruby-version - the Ruby version to use for lein ruby : "1.8" or "1.9" (default)

• :ruby-gem-dir - the directory to use for gems, relative to the project root (defaults to vendor/gems )

Answer 2

It seems it is possible to use Mavern plugins and dependancies. Looking at Leiningen's GitHub , I found the following pieces of information that seem relevant:

:dependencies [[org.clojure/clojure "1.8.0"]
               [clj-http "2.0.0"]]

Leiningen will automatically download the clj-http jar and make sure it is on your classpath.

...

Leiningen reuses existing JVM repository infrastructure. There are several popular open source repositories. Leiningen by default will use two of them: clojars.org and Maven Central.

You can add third-party repositories by setting the :repositories key in project.clj. See the sample.project.clj for examples on how to do so.
