How to append /META-INF/BenchmarkList to jmh task to fix “ERROR: Unable to find the resource: /META-INF/BenchmarkList”

Question

I'm new to micro bench-marking in general. When I execute the JMH task in my project I get "ERROR: Unable to find the resource: /META-INF/BenchmarkList", I believe is created by jmh-generator-annprocess. I am using Gradle and I am trying to figure out if jmh-generator-annprocess is even working? Will it work properly for Gradle or do I need to use the Maven plugin or something?

Answer 1

There was a couple of issues

1. JMHSample_02_BenchmarkModes class was in incorrectly named java class
2. build.gradle was missing apply plugin: "me.champeau.gradle.jmh" declaration
3. In jmhJar section Main-Class manifest entry was overridden (which is unnecessary)

I've made a PR with above fixes. After applying it you can run performance tests using

java -jar build/libs/JMH-Studies-jmh.jar
