Could not initialize class org.apache.jmeter.protocol.http.proxy.ProxyControl

Hi, I'm trying to run my java code in IntelliJ and also trying to initialize apache JMeter, but the following error is shown... Can someone please explain what could be wrong?

As per NoClassDefFoundError description:

Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.

The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.

You need to have at least:

  1. Everything from JMeter's "lib" folder
  2. Everything from JMeter's "lib/ext" folder

in your project classpath, once done you will be able to run your code.
