=== Build feature properties

A `BuildFeature` status properties are represented with `Provider<Boolean>` types.

The link:{javadocPath}/org/gradle/api/configuration/BuildFeature.html#getRequested--[`BuildFeature.getRequested()`] status of a build feature determines if the user requested to enable or disable the feature.

Build logic or plugin implementations can detect if the configuration cache is enabled for a given build, and react to it accordingly.
The link:{javadocPath}/org/gradle/api/configuration/BuildFeature.html#getActive--[active] status of the configuration cache is provided in the corresponding link:{javadocPath}/org/gradle/api/configuration/BuildFeatures.html#getConfigurationCache--[build feature].
