Make build compatible with Gradle configuration cache

[ljacomet]

Gradle 6.6 will introduce a configuration cache.

This plugin can be applied and be compatible with the feature. However its build probably requires some work.

[Sineaggi]

From my limited testing it looks like this plugin is compatible with the gradle plugin cache already. It's only when there's a configuration failure does the gradle configuration cache complain.

With loggingCapabilities.enforceLogback()

~/git/test-logging-libraries % ./gradlew run
Configuration cache is an incubating feature.
Calculating task graph as no configuration cache is available for tasks: run

> Task :app:run
Hello World!
22:15:50.028 [main] INFO test.logging.libraries.App - kek

BUILD SUCCESSFUL in 1s
2 actionable tasks: 1 executed, 1 up-to-date
Configuration cache entry stored.

Without loggingCapabilities.enforceLogback()

 ~/git/test-logging-libraries % ./gradlew run
Configuration cache is an incubating feature.
Calculating task graph as configuration cache cannot be reused because file 'app/build.gradle.kts' has changed.

EDIT: Testing with Gradle 7.0 on jdk-16 on macOS Big Sur

[ljacomet]

Currently the build does not accept the configuration cache because the license plugin used is not compatible.

Closing as obsolete since the plugin code moved elsewhere.
