[jira] [Updated] (GROOVY-7814) Consider allowing Groovy to support Arrays of arbitrary annotations as the return type of an annotation definition member

["Paul King (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-7814?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul King updated GROOVY-7814:
------------------------------
    Description: 
This feature suggestion is proposing to extend the allowable return types for members in annotation definitions.
{code}
import java.lang.annotation.*

@Retention(RetentionPolicy.RUNTIME)
@Target([ElementType.TYPE])
@interface AnyAnnotationCollection {
    Annotation[] value()
}
{code}
In this example, Java would require a specific annotation class instead of just {{Annotation}}.
Usage of the above annotation definition would look like:
{code}
@AnyAnnotationCollection([
    @Grab('foo:bar:1.0'),
    @AnyAnnotationCollection([
        @FunctionalInterface,
        @Deprecated
    ])
])
class Dummy{}
assert Dummy.annotations[0].value().size() == 2
assert Dummy.annotations[0].value()[1].value()[0].annotationType().simpleName == 'FunctionalInterface'
{code}
The nesting here is not in any way required but supported.
