title: JMeter: No Class Def Found Error: kg/apc/jmeter/JMeterPluginsUtils
body: <p>I'm trying to run a JMeter test and I keep getting the error listed below. I'm running in non-gui mode on an EC2 instance. I know I'm missing a .jar file and that's what is causing the error. But when I head over to Apache to look through their JMeter plugins, I can't find one that resolves this error.</p>
