I have an Epsilon project that works fine, I have two EOL scripts to perform my calculations, one to populate my models and one for code generation.
I would like to create a Java class that loads the necessary dependencies from Epsilon Packages to load the models, run the EOL script, and the code generation part.
I have taken this example from the repositories but eclipse con resolve this "import org.eclipse.epsilon.emc.emf.EmfModel",
this is my first project in this domain and i don't know how to solve it.
What I have to do for from the JavaClass run Epsilon scripts.

This was the link I followed:
https://git.eclipse.org/c/epsilon/org.eclipse.epsilon.git/tree/examples/org.eclipse.epsilon.examples.standalone/src/org/eclipse/epsilon/examples/standalone/EpsilonStandaloneExample.java

You need to use the entire project as your starting point, not just the .java file. The project is Maven-based, and it automatically fetches the Epsilon JAR files from Maven Central.

Please see this article in the Epsilon website:

I have read the article, but I still have doubts about the workflow to follow.
The Java class from what context I create it, the example is not completely clear to me. I simply create a Java class and
add this code and my eclipse does not recognize it.
Could you clarify me how I should proceed to create a Java class that is integrated with the Project dependencies?
