I am benchmarking some methods using jmh through a spring boot application. When i run it through IDE it gives me benchmarks but when i package it with maven and run it through CMD it gives the below stack trace.
# Run progress: 0.00% complete, ETA 00:11:00
# Fork: 1 of 1
Error: Could not find or load main class org.openjdk.jmh.runner.ForkedMain

Benchmark had encountered error, and fail on error was requested

I have tried setting classpath explicitly through info from bunch of forums but that didn't help running the application through cmd. Any help would be appreciated.
Thanks!
Had same ClassNotFoundException
with Gradle + JMH which was an incompatibility bug fixed in recent versions (jmh-gradle-plugin >= 0.5.0). As blase as this advice is: try upgrading (or downgrading) and seeing if it still occurs.
