How do I build my IntelliJ IDEA project without getting a SecurityException

Question

I'm currently developing something, and I want to use the Eclipse Paho library in order to connect to an MQTT server. The problem is that whenever I build my project and run it (I run it on a Minecraft Spigot server, 1.16.5) I get the following error:

I'm building using artifacts inside of IntelliJ IDEA. Here's the artifact I was using:

As you can see I extracted the Paho library into my output root. Could anybody help me solve this issue?
