Forum: JRuby JRuby and maven ?

I would like to know what the best way to use JRuby with maven is ? I 
found jbundler and it seems as if jgem can load jars from a central 
repository, but what if I need to load the dependencies from another 
repository ?

you can add

repository 'http://....'

to your Jarfile to declare another maven repository beside maven 
central.

but if you want to use maven with jruby than have a look at

https://github.com/torquebox/jruby-maven-plugins

jbundler is a way to add jar dependencies to your jruby project.

PS I am just about to update the jbundler readme about the repo 
declaration

If you are looking for dependency resolution, I wrote
https://github.com/mguymon/lock_jar as a Frankenstein between Maven and
Bundler for JRuby. Similar to Bundler, you create a Jarfile with Jar
specific properties. An example Jarfile:

    repository
    'http://repository.jboss.org/nexus/content/groups/p...

    # default scope is compile
    jar "org.apache.mina:mina-core:2.0.4"

    scope 'runtime' do
       jar 'org.apache.tomcat:servlet-api:jar:6.0.35'
    end

    scope 'test' do
       jar 'junit:junit:jar:4.10'
    end

By calling LockJar.lock, all the Jar dependencies are resolved and
downloaded using Maven's Aether lib and generates the lockfile. An
example lockfile:

    ---
    repositories:
       - http://repository.jboss.org/nexus/content/groups/p...
    scopes:
       compile:
         dependencies:
           - org.apache.mina:mina-core:2.0.4
         resolved_dependencies:
           - org.apache.mina:mina-core:jar:2.0.4
           - org.slf4j:slf4j-api:jar:1.6.1
           - com.slackworks:modelcitizen:jar:0.2.2
           - commons-lang:commons-lang:jar:2.6
           - commons-beanutils:commons-beanutils:jar:1.8.3
           - commons-logging:commons-logging:jar:1.1.1
           - ch.qos.logback:logback-classic:jar:0.9.24
           - ch.qos.logback:logback-core:jar:0.9.24
           - com.metapossum:metapossum-scanner:jar:1.0
           - commons-io:commons-io:jar:1.4
           - junit:junit:jar:4.7
       runtime:
         dependencies:
           - org.apache.tomcat:servlet-api:jar:6.0.35
         resolved_dependencies:
           - org.apache.tomcat:servlet-api:jar:6.0.35
       test:
         dependencies:
           - junit:junit:jar:4.10
         resolved_dependencies:
           - junit:junit:jar:4.10
           - org.hamcrest:hamcrest-core:jar:1.1

Finally, to load the classpath once you have a lockfile, you simply call
LockJar.load. You can specify which scopes you want loaded by passing in
an array of scope names, e.g. LockJar.load( ['runtime', 'test'] ).
LockJar defaults to the runtime and compile scopes.

You can actually skip the Jarfile and lockfile process by having the
LockJar.load resolve dependences with the :resolve => true parameter and
passing in a Jarfile config as the block. An example:

    LockJar.load( :resolve => true ) do
       jar 
'org.eclipse.jetty:example-jetty-embedded:jar:8.1.2.v20120308'
    end

LockJar also can integrate directly with Bundler and Buildr.

Thanks,

worked like a charm.
