Gradle 8 deprecation warnings

[NotMyFault]

Building with --warning-mode all reveals:

Java toolchain auto-provisioning enabled, but no java toolchain repositories declared by the build. Will rely on the built-in repository. This behaviour has been deprecated and is scheduled to be removed in Gradle 8.0. In order to declare a repository for java toolchains, you must edit your settings script and add one via the toolchainManagement block. See https://docs.gradle.org/7.6.1/userguide/toolchains.html#sec:provisioning for more details.
