        and:

Reason: A property without annotation isn't considered during up-to-date checking.

Possible solutions:
  1. Add something cool.
  2. Mark it as @Internal.

${validationMessage("missing_annotation")}
"""
    }

    def "tests output of ignoredAnnotationOnField"() {
        when:
        render ignoredAnnotationOnField {
            type('Bear').property('claws')

    String missingAnnotationMessage(@DelegatesTo(value = MissingAnnotation, strategy = Closure.DELEGATE_FIRST) Closure<?> spec = {}) {
        missingAnnotationConfig(spec).render()
    }

    MissingAnnotation missingAnnotationConfig(@DelegatesTo(value = MissingAnnotation, strategy = Closure.DELEGATE_FIRST) Closure<?> spec) {
        def config = display(MissingAnnotation, 'missing_annotation', spec)

To fix this problem, you must remove the property.

== Properties without annotations

This error indicates that a property isn't annotated with an input or output annotation.
