Description

Quarkus introduced a migration tool in the past (see the documentation - https://quarkus.io/guides/update-quarkus). Camel Quarkus leveraged the tool and added support for migration of the camel-quarkus projects.

 

Now is the right time to bring such migrations into plain Camel.

Current status:

• Quarkus migration tool uses OpenRewrite recipes
• Camel Quarkus added recipes for the migration of plain Camel from 3.x to 4.x •
• Recipes are located in the Quarkus repository ( https://github.com/quarkusio/quarkus-updates/tree/main/recipes/src/main/java/io/quarkus/updates/camel )

I'd like to propose several improvements:

1. The recipes should be moved into the Camel repository (together with the tests)
2. There should be an easy way of running those recipes on plain Camel projects
3. The recipes module has to become a part of the released Camel bits (it could be added as the last released module as nothing should depend on it)
4. The Quarkus repository has to be refactored to use the Camel recipes (and tests) artifact
