Migration Summary

Completed Tasks

  1. Code Migration:

    • Migrated code from :shared-kernel to core modules
    • Migrated code from :master-data to masterdata modules
    • Migrated code from :member-management to members modules
    • Migrated code from :horse-registry to horses modules
    • Migrated code from :event-management to events modules
    • Migrated code from :api-gateway to infrastructure/gateway
    • Migrated code from :composeApp to client modules

  2. Package Updates:

    • Updated package declarations in all migrated files
    • Updated import statements to reflect the new package structure
    • Updated references to old packages in code

Remaining Issues

  1. Compilation Errors:

    • Client Modules: The migrated client code from :composeApp uses Kotlin Multiplatform and Compose Multiplatform, but the new client modules are configured for JVM-only. This requires either:

      • Updating the client module build files to support multiplatform
      • Refactoring the client code to work with JVM-only configuration

    • Shadow JAR Tasks: Failed for several modules (masterdata-api, horses-api, events-api)

    • Other Compilation Issues: Various other compilation errors need to be addressed

  2. Testing:

    • Tests need to be updated and run to verify the migration was successful

Recommendations

  1. Fix Compilation Issues:

    • Focus on core and vertical modules first
    • Address client module issues as a separate task
    • Run a full build after fixing issues

  2. Run Tests:

    • Update and run tests to verify functionality

  3. Clean Up Old Modules:

    • Run the cleanup script (./cleanup_old_modules.sh) only after verifying that all new modules build successfully
    • Consider running in dry run mode first (./cleanup_old_modules.sh --dry-run)

Conclusion

The code migration from the old module structure to the new modular architecture has been completed. The code has been moved to the appropriate new modules, and package declarations and imports have been updated. However, there are still compilation issues that need to be addressed before the migration can be considered fully successful.

The most significant challenge is with the client modules, which require additional work to properly support the multiplatform code that was migrated from the :composeApp module. This should be addressed as a follow-up task.

Once all compilation issues are resolved and tests are passing, the old modules can be safely removed using the provided cleanup script.
