        Filing feature requests is one of the most popular ways to contribute to Guava.


        Be aware, though: most feature requests are not accepted, even if they're suggested by
        a full-time Guava team member. [Feedback](https://stackoverflow.com/a/4543114) from our

    def "toggling feature flag with system property invalidates cache"() {

        def configurationCache = newConfigurationCacheFixture()

When the `requested` provider value is:

- `true` -- the user opted in for using the feature
- `false` -- the user opted out from using the feature
- `undefined` -- the user neither opted in nor opted out from using the feature

The link:{javadocPath}/org/gradle/api/configuration/BuildFeature.html#getActive--[`BuildFeature.getActive()`] status of a build feature is always defined.
