Contributing

First make sure all the required dependencies are installed:

bundle install

Then compile the required Java code:

bundle exec rake compile

For this you'll need to have Java 1.7 and Maven installed. These requirements are verified for you before the Rake task calls Maven.

Testing

To run the tests (which are powered by Cucumber), simply run the following:

bundle exec rake

This will take care of verifying the requirements, installing the required Java packages and running the tests.

For more information on the available Rake tasks run the following:

bundle exec rake -T

Structure

This repository comes in two parts: a collection of Java source files and Ruby source files. The Java code can be found in the core/ directory, everything else will be Ruby source code.
