This error indicates that you have annotated a type with `@CacheableTransform` on something that is not an artifact transform, or `@CacheableTask` on something which is not a `Task`.

The solution is to remove the annotation.

For tasks, the annotation to use is `@CacheableTask`.
For artifact transforms, the annotation to use is `@CacheableTransform`
