Enhancement: Can Helidon examples moved to a separate repository?

[thesurenk]

Can Helidon examples moved to a separate repository so the platform "core" is seprate

Why?

1. This will be helpful for contributors to submit PR's. As of now we have to FORK the entire repo with core and examples.
2. Merging to a respective folder may become simpler

Challenges:

1. Most examples depend on parent pom's, moving them out to separate folder may pose challenges with build failures.
2. Standalone examples like helidon-standalone-quickstart-mp will work fine.

This will be helpful for contributors

This is something that we do have in scope.

Currently the examples that inherit an "application parent pom" must reference it using <relativePath> and indeed these examples cannot be moved or extracted as-is without updating the <relativePath>.

If we do move the examples, the development work will have to be carried out in branches where the version is a SNAPSHOT version for the corresponding Helidon version. Building the examples will still requires a local build of Helidon unless we deploy SNAPSHOT regularly to a remote maven repository (also in scope).

Tags will offer fully functional examples, each of them being properly self-contained.
We can decide to merge the latest tag in master in and do the development work in branches named "dev" and "1.x".

I agree @romain-grecourt (and i've also noted some challenges). This was an observation and can be a back-burner and can be addressed when this may become a problem as Helidon platform/community grows.

This has been completed for Helidon 3. After a little soak time we will do it for Helidon 4.

• 3.x example removal #8437
• 3.x Examples validation flow for external examples repo #7889
• Helidon 3 Examples

We will use #5887 to track work for Helidon 4
