Ceylon project using the Java API
Once you've cloned the project, navigate to the project's root directory and compile it with ceylon compile. This creates a module named hello. From there you can either run the module with ceylon run hello/1.0.0 or, for added flexibility, create a Fat Jar with ceylon fat-jar hello/1.0.0 which generates hello-1.0.0.jar that you can run with java -jar hello-1.0.0.jar
