Recommended Posts

So I was trying to open the server file on my mac with 8GB RAM. This is the file I was using 

#!/bin/bash
export JAVA_HOME=$(/usr/libexec/java_home -v 13.0.2)
cd "$(dirname "$0")"
exec Java -Xms8G -Xmx8G -jar server.jar

 

when I open this I get this error

A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException
