I have been working on a MDE project with Eclipse Epsilun, I have an EOL script to populate my models and it performs some calculations. I have an EGL generator script that generates a web page with the models data.
I would like to automate this process. When I make a change I have to run the script that populates the model and then the code generation.

How can I create a Java code that launches these two EOL scripts?

Meta Model:
index.php/fa/42177/0/

EOL script:
index.php/fa/42178/0/

EGX script:
index.php/fa/42179/0/

For me is no so clear the article, i just copy this code to my JavaClass

                System.out.println("Hola Mundo");
		EolModule module = new EolModule();
		module.parse(new File("program.eol"));
		module.execute();

The EolModule cannot be resolved.
How to add this module ?

EolModule is part of the first Maven dependency in https://www.eclipse.org/epsilon/doc/articles/run-epsilon-from-java/#dependencies
