错误：运行 mvn test 时无法找到资源：/META-INF/BenchmarkList

Question

我编写了一个基准测试并放入 src/test 文件夹中。代码：

public class BenchMarkTest {
    @State(Scope.Benchmark)
    public static class BenchmarkState {
        ...
    }

    @Benchmark
    public void singleThread(BenchmarkState state) {
        ...
    }

    @Benchmark
    public void executorService(BenchmarkState state) {
        ...
    }

    @Benchmark
    public void forkJointPool(BenchmarkState state) {
        ...
    }

    @Test
    public void launchBenchmark() throws Exception {
        Options opt = new OptionsBuilder()
            .include(this.getClass().getName() + ".*")
            .mode(Mode.AverageTime)
            .timeUnit(TimeUnit.MICROSECONDS)
            .warmupTime(TimeValue.seconds(1))
            .warmupIterations(1)
            .measurementTime(TimeValue.seconds(1))
            .measurementIterations(1)
            .threads(3)
            .forks(1)
            .shouldFailOnError(true)
            .build();

        new Runner(opt).run();
    }
}

所以当我通过Intellij IDEA运行配置调用launchBenchmark时它运行正常。 但是当我尝试在“mvn clean”之后运行“mvn test”时，它失败并出现错误： 错误：无法找到资源：/META-INF/BenchmarkList

解决方案是添加特定路径：
