ERROR: Unable to find the resource: /META-INF/BenchmarkList when running JMH with gradle

Question

I want to benchmark my application using JMH. I am using JMH with gradle as build tool. The github repository is here.

But whenever I run the application com.demo.aerospike.JMHAerospikeSpringData I get below error.

$ gradle run

> Configure project :
Task :jmh Last added: null

> Task :run
JMHAerospikeSpringData is running ...
Exception in thread "main" java.lang.RuntimeException: ERROR: Unable to find the resource: /META-INF/BenchmarkList

* What went wrong:

I tried different solutions in other stackoverflow but couldn't help.

Any idea what I'm missing.

@Atelier - I updated the repo. – Strop

Answer 1

I have resolved this problem by adding this dependency to my project:

testAnnotationProcessor "org.openjdk.jmh:jmh-generator-annprocess:$jmhVersion"

next to

testImplementation "org.openjdk.jmh:jmh-core:$jmhVersion"

Answer 2

implementation 'org.openjdk.jmh:jmh-core:1.33'

annotationProcessor 'org.openjdk.jmh:jmh-generator-annprocess:1.33'

just like lombok

Welcome to Stack Overflow! While this code may solve the question, including an explanation of how and why this solves the problem would really help to improve the quality of your post, and probably result in more up-votes. Remember that you are answering the question for readers in the future, not just the person asking now. Please edit your answer to add explanations and give an indication of what limitations and assumptions apply. "just like lombok" ist not enough. And stackoverflow.com/editing-help – Sitin

Please add some explanation to your answer such that others can learn from it – Gorton

Answer 3

Try running without gradle daemon:

gradle --stop
gradle --no-daemon jmh

Same result for me. – Phanerogam

Answer 4

Not sure how is your project setup like because I can't find com.demo.aerospike.JMHAerospikeSpringData in your repo. Maybe you want to check this project out to get some ideas to try.
