This looks super interesting, but as far as I can tell they don’t go into how to inform downstream users to add your recipes to their maven/gradle configuration when you make a breaking change.

In my head, the ideal flow would be an annotation on your library function/class which triggers an IntelliJ suggestion for downstream users affected by your breaking change to run the automated refactor for them. Kinda like a more helpful @Deprecated.

It would definitely be nice to have this generated from a deprecated like annotation!

The maven plug-in seems to use the recipes directly as dependencies: https://github.com/openrewrite/rewrite-maven-plugin

In our internal situation the parent Pom could already control this plug-in definition including versions of the recipes. At the very least the recipes could follow the same version as the artefact.

I thought I saw somewhere where the recipe was bundled with the artefact itself. That is very neat for simple usecase.

However, it suffers from the same flaw as the native-image configuration for GraalVM in artifacts. Sometimes the configuration/recipe needs to change. Eg because of new insights or because it is incompatible with new versions of GraalVM/open rewrite. So I suppose having an extra version dimension Could solve this. Then one can always depend on the latest version of the recipe for that artifact.
