# Internal

@Documented
@Retention(value = RetentionPolicy.RUNTIME)
@Target(value = [ElementType.METHOD, ElementType.FIELD])
annotation class Internal(source)

Attached to a task property to indicate that the property is not to be taken into account for up-to-date checking.

This annotation should be attached to the getter method in Java or the property in Groovy. Annotations on setters or just the field in Java are ignored.

This will cause the task not to be considered out-of-date when the property has changed.

Properties annotated with `@Internal` are not subject to presence validation and are treated as inherently optional. There is no need, and it is an error, to also annotate them with org.gradle.api.tasks.Optional.
