java微基準測試JMH引入報錯RuntimeException: ERROR: Unable to find the resource: /META-INF/BenchmarkList

項目引入JMH進行性能測試，完整demo

運行之後控制檯報錯：

Exception in thread "main" java.lang.RuntimeException: ERROR: Unable to find the resource: /META-INF/BenchmarkList
	at org.openjdk.jmh.runner.AbstractResourceReader.getReaders(AbstractResourceReader.java:98)

根據https://stackoverflow.com/questions/38056899/jmh-unable-to-find-the-resource-meta-inf-benchmarklist

給出的解決方法修改pom文件，記得mvn clean and install之後纔會生效！
