[jira] [Comment Edited] (GROOVY-9801) Stub generator omits default interface methods

["Keegan Witt (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-9801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17276029#comment-17276029 ]

--------------------------------------------------------------

Interface default methods are currently implemented with traits. I think there's probably not any benefit to adding {{default}} to the stubs until we change how it's implemented in the bytecode, since the Java class won't be able to invoke the default method.

> When presented with a Groovy interface that has a default method (shiny and new!) the stub generator omits the "default" part, leading to compilation failures in Java classes due to unimplemented abstract methods.
> {code:groovy}
> interface HasDefaultMethod {
>   default void method() { }
> }
> {code}
> {code:java}
> import java.lang.*;
> import java.util.*;
> import java.io.*;
> import java.net.*;
> import groovy.lang.*;
> import groovy.util.*;
> @groovy.transform.Trait() public interface HasDefaultMethod
>   {
> ;
>   void method();
> }
> {code}
> (The stray semicolon is also odd but doesn't appear to be pathological.)
