Java 版本\xef\xbc\x9agraalvm-11\n通过 Gradle\xef\xbc\x9a6.8.3 构建

官方示例的测试代码：

\n

public class Sample_helloworld {\n\n\n    @Benchmark\n    public void printHello ()\n    {\n\n    }\n\n    public static void main (String[] args) throws RunnerException {\n        var opt = new OptionsBuilder()\n                .include(Sample_helloworld.class.getName())\n                .forks(1)\n                .build() ;\n\n        new Runner(opt).run() ;\n    }\n}\n
