Programmatically running EMF code generation

Question

I have created an EMF model with extension .system which will generate the code for my work.

Now I can generate code using launch code generation action from Eclipse. But I want to generate the code by launching the code generation from a stand-alone program.

How do I achieve this?

Details: I have created a plugin from EMF model and have inlcluded in the Eclipse.

I will created .system files from out of my plugin and I can generate code from my plugins.

I have observed that when I click launch the code generation it is starting a LauchAction class from my plugin.

How do I start my LaunchAction class from a stand-alone Java program?

My aim is to run my created .system model and generate the code from a stand-alone Java program.

How do I achieve this?

You might consider refactoring this question. 1. Turn it into a question. 2. What is the exact step you are missing? Example: What snip of code and configuration do I need to make an EMF model into Java Stubs. 3. Proof read. I typically can help in this space. You might message me through this site if you still need help and you update the question. — Ted Johnson

You could call Eclipse from the command line. Something similar to this:

eclipse.exe -noSplash -data ${workspace_location} -model -edit -editor -tests -application org.eclipse.emf.codegen.ecore.Generator ${genmodel}

This command will start Eclipse silently and will generate mode code (-model), edit plug-in (-edit), editor plug-in (-editor), and the test plug-in (-tests). Leave out any of these parameters if they are not needed.

I don't know how to solve your problem, but I think it is doable. I think you have to look at the EMF source code to check how the code generation works.

Here are some starting points:

If you have PDE and the EMF tools, use use Import > Plug-ins and Fragments to get the EMF plugin into your Eclipse workspace.
Otherwise, clone and import the following Git repository:
```
https://git.eclipse.org/c/emf/org.eclipse.emf.git/
```

Have a look at the following file, maybe you can find what you need there:

plugins/org.eclipse.emf.codegen.ecore.ui/src/org/eclipse/emf/codegen/ecore/genmodel/handler/GenerateHandler.java

Otherwise, look in the org.eclipse.emf.codegen.ecore plugin.

Good luck! It's an interesting problem! Please report back here if you solve it!
