Warning: The option '-H:ReflectionConfigurationResources=META-INF/native-image/io.micrometer/micrometer-core/reflect-config.json' is experimental and must be enabled via '-H:+UnlockExperimentalVMOptions' in the future.

--link-at-build-time  require types to be fully defined at image build-time. If used
                      without args, all classes in scope of the option are required to
