* Specifies that a JVM default method should be generated for non-abstract Kotlin interface member. * Specifies that a JVM default method should be generated for non-abstract Kotlin interface member.
* *
* Usages of this annotation require an explicit compilation argument to be specified: * This annotation can no longer be used. It has been superseded by the new `-Xjvm-default` modes `all` and `all-compatibility`,
* either `-Xjvm-default=enable` or `-Xjvm-default=compatibility`. * and the new annotations `@JvmDefaultWithCompatibility` and `@JvmDefaultWithoutCompatibility`.
*
* * with `-Xjvm-default=enable`, only default method in interface is generated for each @[JvmDefault] method.
* In this mode, annotating an existing method with @[JvmDefault] can break binary compatibility, because it will effectively
* remove the method from the `DefaultImpls` class.
* * with `-Xjvm-default=compatibility`, in addition to the default interface method, a compatibility accessor is generated
* in the `DefaultImpls` class, that calls the default interface method via a synthetic accessor.
* In this mode, annotating an existing method with @[JvmDefault] is binary compatible, but results in more methods in bytecode.
*
* Removing this annotation from an interface member is a binary incompatible change in both modes.
*
* Generation of default methods is only possible with JVM target bytecode version 1.8 (`-jvm-target 1.8`) or higher.
*
* @[JvmDefault] methods are excluded from interface delegation.
