public @interface NonNullApi

Deprecated.

Deprecated in Gradle 9 for removal in Gradle 10. Prefer JSpecify annotations such as NullMarked and Nullable. Note that you can also still use JSR305 annotations such as Nonnull and Nullable.

Marks a type or a whole package as providing a non-null API by default. All parameter and return types are assumed to be Nonnull unless specifically marked as Nullable. All types of an annotated package inherit the package rule. Subpackages do not inherit nullability rules and must be annotated.
