Claus Ibsen commented on CAMEL-24709:
-------------------------------------
PR: https://github.com/apache/camel/pull/26455
Naming the missing artifact at runtime is not possible from the classpath
metadata alone (it ships in the same jar as the bean); that is tracked as
CAMEL-24752.

> camel-yaml-dsl - class not found hint for beans should use the bean metadata

> The class-not-found hint in the YAML beans deserializer (CAMEL-24702, PR
> 26361) suggests a built-in class only for names ending in
> AggregationStrategy, by trying the hardcoded package
> org.apache.camel.processor.aggregate. Camel ships many more out-of-the-box
> beans (aggregation repositories, idempotent repositories, header filter
> strategies, key-value repositories, ...) in camel-core and in some 30
> components, and the catalog lists them (camel-catalog beans/*.json with
> javaType and interfaceType).
> The same information is on the classpath at runtime, generated by the build
> tools into every jar that has such beans:
> META-INF/services/org/apache/camel/bean.properties (the bean names) and
> META-INF/services/org/apache/camel/bean/<Name>.json (javaType, interfaceType,
> description). The runtime cannot depend on camel-catalog, but it can read
> these resources, so the hint can be data driven:
> * {{type: "#class:com.foo.UseLatestAggregationStrategy"}} (not found) -> did
> you mean org.apache.camel.processor.aggregate.UseLatestAggregationStrategy
> (org.apache.camel.AggregationStrategy)?
> * {{type: "#class:MemoryAggregationRepository"}} -> the same, from the
> repository bean metadata
> * a name that is not a built-in bean keeps the generic hint (check the
> package name; a class from another library needs its dependency added)
> Possibly also: when the missing class name does not match a bean by simple
> name, but the option that references it needs an interface
> (aggregationStrategy, idempotentRepository), list the built-in beans of that
> interface from the same metadata. The write-time check in camel-jbang
> (camel_validate_source) already does this from the catalog
> (CatalogDocs.beansOfInterface); the runtime hint should give the same answer
> from the classpath resources.
> Found while reviewing PR 26361.
