It happened to me that I alway have problem with eclipse not recognizing my ecore file, since it can not find the appropriate one.

Here is the question :

1- It seems that there is a kind of rep. for the eclipse that ecore file is registered there, so if any program or tool is requiring ecore core file it request eclipse to look for that in that registery and tell him if the file registered or not? Is this true?

2- if 1 is true how I can register my ecore file in this repository (by code and manually, i.e. in eclipse env.)?

3- How can I look up this repository (e.g., list the registered ecore files?

Any clarification is appreciated.

Thanks

There's EPackage.Registry.INSTANCE and generated models in the
plugin.xml register the Ecore model there via
org.eclipse.emf.ecore.generated_package.

The generator should just produce the correct registration in the
plugin.xml automatically.

You can inspect the EPackage.Registry.INSTANCE.

Can you please take a look at this question here. I still could not solve this problem. To be honest, I could not follow your answer; I do not want to create a plugin nor I want to generate a code for my ecore file. I just simply want it to be recognized by eclipse, and then I can refer to that by just using its package URI instead of using relative path or something. Is this possible to do?

No, only registered models (one installed into the running IDE or the
Target platform and registered in the bundle's plugin.xml) are available
via their nsURI.

It seems that Epsilon provides a functionality to register EPackages of ecore files in the workspace into the running eclipse instance.
Have a look at this tutorial (section "Register library.ecore"):
https://eclipse.org/epsilon/doc/articles/reflective-emf-tutorial/

I used this function a while ago and it seemed that the registration is persisted.
You will need to install the Epsilon plugin, however (but not create a dedicated plugin yourself).

You can look up registered packages by opening the "EPackage Registry" view.

Regards,
Maximilian
