You should be able to use "default []". I don't think it supports "default new Class[0]". Is this under Static Type Checking or Static Compilation?
NOTE: https://issues.apache.org/jira/browse/GROOVY-11492 item 3 covers the missing "default {}" support. ________________________________ From: Saravanan Palanichamy <chava...@gmail.com> Sent: Tuesday, April 15, 2025 4:21 AM To: us...@groovy.apache.org <us...@groovy.apache.org>; dev@groovy.apache.org <dev@groovy.apache.org> Subject: [EXT] Default for annotation members with type class External Email: Use caution with links and attachments. Hello Groovy users What is the right way to define this java annotation in groovy? I am testing this out in Groovy 5.0, I have not tried 4.x. I tried using [] after the default keyword, but I get the error "Cannot return value of type java.util.ArrayList<#E> for method returning java.lang.Class<?>[]" and "Cannot return value of type java.util.ArrayList<#E> for method returning java.lang.Class<? extends MyClazz>[]" @Target({ ElementType.METHOD }) @Retention(RetentionPolicy.RUNTIME) public @interface MyAnnotation { Class<?>[] groups() default {}; Class<? extends MyClazz>[] payloads() default {}; } regards Saravanan
