Hello guys,

I have download the jmx_prometheus_javaagent-0.12.0.jar also version 0.11.0 and also created config.yml file in my linux system. Java 1.8 is installed in my linux system. I was trying to setup jmx_exporter as agent using below command.

java -javaagent:./jmx_prometheus_javaagent-0.12.0.jar=8080:config.yml -jar jmx_prometheus_javaagent-0.12.0.jar

But it gives the error.

abinavviswanathan@Abinavs-MacBook-Pro-2 META-INF % cat MANIFEST.MF 
Manifest-Version: 1.0
Implementation-Title: jmx_prometheus_javaagent
Premain-Class: io.prometheus.jmx.shaded.io.prometheus.jmx.JavaAgent
Implementation-Version: 0.16.1
Archiver-Version: Plexus Archiver
Built-By: fabian
Agent-Class: io.prometheus.jmx.shaded.io.prometheus.jmx.JavaAgent
Created-By: Apache Maven 3.8.1
Build-Jdk: 1.8.0_292

The MANIFEST.MF does not have Main-Class attribute specified.

I believe this is a bug and thus I am getting the error above.

I have the same issue, and checking the jar I’m trying to scrape I see this in the MANIFEST.MF file

Premain-Class: org.apache.cassandra.infrastructure.continuations.CAgent

The jar doesn’t have a main class like

Main-Class: com.mypackage.MyClass
