Native build troubles with Copilot and Hilla @Menu

[deniz-frick]

Describe the bug

vaadin-copilot is in the classpath even when the production classpath is used.

After creating a native build as described in the vaadin docs (mvn -Pproduction -Pnative native:compile), missing reflection configuration and copilot being on the classpath causes an exception in SpringBridge.call.

This can be prevented by excluding vaadin copilot in the production profile as per the edit in this gist. The gist also contains the logfiles with complete stacktraces.

After doing this and building another native build, this also fails with the following exception:

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of 'com.vaadin.hilla.route.records.ClientViewConfig': cannot deserialize from Object value (no delegate- or property-based Creator): this appears to be a native image, in which case you may need to configure reflection for the class that is to be deserialized

So hilla is missing reflection information that is essential for graalvm native builds to work as intended.

Expected-behavior

Native builds should work without issue if no external dependencies are used.

I also encountered issues with hibernate-spatial and native builds but that is of course not caused by vaadin.

Reproduction

1. Download this starter app with flow and hilla views.
2. Run the application once normally (sping-boot:run) to check if everything is working.
3. Create a production build.
4. Run it and see it fail (this causes log1.txt - see gist)
5. Change the pom.xml (add an exclusion for vaadin-copilot in the production profile - see gist)
6. Add a @Menu() annotation to EmptyView
7. Add vaadin.expose-server-routes-to-client=true to the application.properties file to enable @Menu
8. Run it again normally to see both views in the side navigation
9. Create a production build.
10. Run it an see it fail (log2.txt in the gist)

It looks like the project is missing the exclusion of development only artifacts from the production build. Try adding this to the pom.xml https://github.com/vaadin/skeleton-starter-hilla-react/pull/219/files

@Artur- I had a similar fix in place but the second issue with ClientViewConfig is unaffected by this.
Your change fixes the first issue though. 👍
