The question came up before, but wasn't actually answered then. How do you set up buildr to build JRuby projects?

any one has experience with Open Shift and install FreePascal as a cartridge?
I found this but I don't know how make it work :
https://github.com/jhadvig/openshift-pascal-cartridge
I want to know what is the instruction of making FreePascal cartridge.
The following command should install that cartridge for you
rhc app create freepascal https://cartreflect-claytondev.rhcloud.com/reflect?github=jhadvig/openshift-pascal-cartridge
Basically since the manifest.yml file does not contain a Source-Url definition, you need to run it through the cartridge reflector as i did above.
Unfortunately that cartridge also does not seem to install correctly. You should leave an "issue" using the issues tab on that cartridge asking if it is ready for production use or not.
If you want to develop your own cartridge, you can read through the cartridge developers guide here: http://openshift.github.io/documentation/oo_cartridge_developers_guide.html
I'm looking for some build automation tool for JRuby project. Result of this project should be some library that can do stuff. I need to use some Java libraries but I want to work with Ruby. So that's why JRuby.
In this stage, I'm looking for build automation tool that can handle dependencies and download them from remote repository.
I could use Maven for this, but I'm interested in other alternatives that could be more fun to work with.
So yeah, if you are looking for something sexier than Mave, SBT is good option.
Other options are:
Gradle - http://www.gradle.org/ - if you want Groovy rather than scala orientation.
Or Gant - http://gant.codehaus.org/ - for some more in the lines of Ant.
Buildr - http://buildr.apache.org/ - Is another interesting project
I also came across this dead project - http://raven.rubyforge.org/ - But I wonder if something new came to tackle the same item, i.e. using Rake , the ruby build tool, to build java as well.
From a dependency management perspective only, jbundler is a bridge between Maven and bundler that can help you manage your dependencies, whether they are gems or maven artefacts.
Any tutorials or blog are available to start with JRuby on Rails
which guide me to the installation and small JRuby on Rails application ?
I have gone through this Walkthroughs And Tutorials(https://github.com/jruby/jruby/wiki/WalkthroughsAndTutorials) link but most of the JRuby on Rails links are broken.
JRuby and Rails Installation
The easiest way to set up JRuby is using rvm. The following command installs rvm, the latest version if JRuby, and gets the latest version of rails:
$ curl -L https://get.rvm.io | bash -s stable --autolibs=3 --ruby=jruby --gems=rails
On Windows, you can download an installer which will set up JRuby for you. You then need to install rails by running the following command:
jruby -S gem install rails
Set up a Rails project
JRuby’s wiki page JRuby on Rails is a great collection of resources on the topic; it contains in particular a link to that good blog post: http://blog.rubyrockers.com/2011/03/rails3-application-jruby/
In a nutshell, to create a rails project based on JRuby, use the following command, replacing my_app with the name of your project:
rails new my_app -m https://www.jruby.org/templates/default.rb
Rails Development
Once your project is set up, any Rails 3 tutorial will do — it is Ruby after all!
Deployment
For deployment, have a look at:
“specific” solutions like Torquebox or Trinidad,
or warbler to package your app as a war and deploy in traditional Java app server (WebSphere, Weblogic, etc.).
Further Resources
Finally, it is also worth mentioning that Charles Nutter et al's book Using JRuby has a chapter dedicated to JRuby on Rails, and is an invaluable help in JRuby developments.
Ubuntu 10.04LTS
Netbeans 6.9.1 (with embedded JRuby 1.5.1)
JDK6u17 (installed in /opt)
GlassFish Gem 1.0.2
I am using a old JDK because of this bug: http://jira.codehaus.org/browse/JRUBY-4785
I want to install RVM and install another instance of JRuby. But i cant find any information how to set JRuby Java environment to JDK6u17(directory /opt).
I would be grateful for the help.
JRuby on default use system Java. So if i change "system" Java, JRuby will use that one.
I have figured two ways to set specific Java environment.
Set JAVA_HOME.
Here is a good one tutorial:
http://vietpad.sourceforge.net/javaonlinux.html
Update java setting from terminal(works only for JVM installed from apt-get or aptitude).
sudo update-alternatives --config java
That JRuby bug is marked as fixed for JRuby 1.6RC1, so you no longer need to use the old JDK.
I am using RVM and JRuby 1.6RC1 on Ubuntu 10.04 LTS just fine. There are instructions on my website for working with this version of Ubuntu, RVM and JRuby.
You don't need all the instructions, but some of the commands might help, if you get stuck.

(It does tell you how to get a modern JDK installed)
I have recently installed Eclipse Galileo with the PHP Developers Tools. I plan to install the Flash Builder 4 Plug-in to do ActionScript development as well.
I want to use Eclipse to both create an ant build script and execute it to compile ActionScript docs from an ActionScript 3 code library.
The problem is that when I try to run a build.xml file (which every site that answers the ant build questions says it should handle automatically) I never see an option to run it as an Ant Build, not can I find any way to associate XML files to Ant in the Preferences or External Tools dialogs.
I;ve seen numerous tutorials on build Ant build files, but never anything about running the actual build script.
Try to install "Eclipse Java EE Developer Tools" component. It's in "Web, XML, and Java EE Development" of "Galileo - http://download.eclipse.org/releases/galileo" repository.
