Providers:

* Properties with these types are read-only.
* The method link:{javadocPath}/org/gradle/api/provider/Provider.html#get--[Provider.get()] returns the current value of the property.
* A `Provider` can be created from another `Provider` using link:{javadocPath}/org/gradle/api/provider/Provider.html#map-org.gradle.api.Transformer-[Provider.map(Transformer)].

** If it's a new property, expose it as a link:{javadocPath}/org/gradle/api/provider/Property.html[Property] or link:{javadocPath}/org/gradle/api/provider/Provider.html[Provider] using a single getter.
** If it's incubating, change it to use a link:{javadocPath}/org/gradle/api/provider/Property.html[Property] or link:{javadocPath}/org/gradle/api/provider/Provider.html[Provider] using a single getter.

Providers are used to model values that may be computed lazily in your build scripts.

The `ProviderFactory` interface provides methods for creating various types of providers, including:

- `provider(Callable<T> value)` to create a provider with a value that is lazily computed based on a `Callable`.
- `provider(Provider<T> value)` to create a provider that simply wraps an existing provider.
