Add Ecore model of Java module system concepts

[Copilot]

Models the Java 9+ module system (module-info.java) as an EMF Ecore model, enabling programmatic representation and manipulation of module declarations.

Ecore Model (model/model/java-module.ecore)

Six EClasses covering all module directives:

Class	Maps to	Key attributes
Module	module M { ... }	name, containment refs to all directives
Requires	requires [transitive] [static] M	name, transitive, static
Exports	exports pkg [to M1, M2]	name, modules[]
Opens	opens pkg [to M1, M2]	name, modules[]
Provides	provides S with I1, I2	service, implementations[]
Uses	uses S	service

Generated EMF Java Code (model/src/main/java/)

• JavaModulePackage — package singleton with class/feature IDs and Literals inner interface
• JavaModuleFactory — factory interface and implementation
• Model interfaces + impl/ implementations using eDynamicGet/eDynamicSet with dynamic feature delegation
• util/JavaModuleSwitch, util/JavaModuleAdapterFactory — standard EMF visitor/adapter infrastructure

Project Structure

Standard Nasdanika multi-module Maven layout matching sibling models (e.g., bank):

• pom.xml (parent) + model/pom.xml
• model/model/java-module.genmodel
• model/META-INF/MANIFEST.MF (OSGi bundle descriptor)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/Nasdanika-Models/java-module/git/trees/c473643
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
• https://api.github.com/repos/Nasdanika-Models/ncore/git/trees/48a05b2ea9ea59458055493be18b85065d51e962
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
• https://api.github.com/search/code
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
  • Triggering command: /usr/bin/python3 python3 /tmp/search_ecore.py (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Create an ecore model of Java module concepts - module, requires (transitive), exports, opens, provides, uses, ...
