仅运行 testMethod() 的 JMH 基准测试

Question

公共类 MyBenchmark {

@Benchmark
public void otherMethod() {
}

@Benchmark
public void sessionCreation() {
}

public static void main(String[] args) throws RunnerException {
    Options opt = new OptionsBuilder().include(MyBenchmark.class.getSimpleName()).forks(1).build();
    new Runner(opt).run();
}

运行到以下错误：

解决方案是执行 mvn clean install，然后再次运行该程序。像魅力一样工作！
