> Follow-up to CAMEL-24873 (PR https://github.com/apache/camel/pull/26678).
> {{DefaultGroovyScriptCompiler}} now hands a compiled Groovy class with class-level annotations to the registered {{org.apache.camel.spi.CompilePostProcessor}}s. Only camel-kamelet-main ({{AnnotationDependencyInjection}}, wired from {{KameletMain}}) registers such post-processors, so this works with {{camel run}} but not in a project created with {{camel export}}: camel-main compiles the {{.groovy}} file from {{src/main/resources/camel-groovy/}} at startup (via {{camel.main.groovyScriptPattern}}), but nothing binds a {{@BindToRegistry}} class or registers a {{@Converter}} class, and a custom simple function from such a file fails with {{Unknown function}} at runtime. Spring Boot and Quarkus register no post-processors either.
> The simple-advanced and camel-jbang-beans pages document the limitation and point at the inline YAML {{scriptLanguage: groovy}} bean, which works in every runtime.
> Proposal: have camel-main register a {{CompilePostProcessor}} for {{@BindToRegistry}} (and {{@Converter}}) so an exported camel-main project behaves like {{camel run}}; then decide whether Spring Boot / Quarkus should do the same for their own annotations, or whether {{camel export}} should convert an annotated {{.groovy}} file for those runtimes.
