gradle-4.7-with-remote-buildcache.log

[15:46:41] Welcome to Gradle 6.7!
[15:46:41] 
[15:46:41] Here are the highlights of this release:
[15:46:41] - File system watching is ready for production use
[15:46:41] - Declare the version of Java your build requires
[15:46:41] - Java 15 support
[15:46:41] 
[15:46:41] For more details see https://docs.gradle.org/6.7/release-notes.html
[15:46:41] 
[15:46:41] To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: https://docs.gradle.org/6.7/userguide/gradle_daemon.html.
[15:46:42] Daemon will be stopped at the end of the build stopping after processing
[15:46:42] Shared read-only dependency cache is an incubating feature.
