ClassNotFoundException for dependencies on java project in Eclipse

I want to get my PC specs with a java program. I'm trying to make use of Oshi library to get this done but I am having problems implementing the dependencies on my project

I want to simply run this

SystemInfo systemInfo = new SystemInfo();
HardwareAbstractionLayer hardware = systemInfo.getHardware();
CentralProcessor processor = hardware.getProcessor();

System.out.println(processor.toString());

but I'm getting this error: enter image description here

I have added these dependencies from this link: https://search.maven.org/artifact/com.github.oshi/oshi-core/6.3.1/jar

Here is a picture of the Project Explorer Project Explorer

I'm pretty sure that I'm doing something wrong with the dependencies, maybe I am not getting the proper dependencies but I want to know what is happening or exactly which jars I need to add to get Oshi running on my java project

The issue here is the classpath. The dependencies are added to your build path which allows your code to compile but not to your classpath which is where you need them for your code to run.

As Daniel said

Go to the "Run Configurations" dialog (Run -> Run Configurations) for the class you are executing and click on "Dependencies" there

Also Daniel's suggestion

Do yourself a favor and set up your project using Maven. (Configure --> add Maven nature.). You can add dependencies in your pom.xml file and Eclipse/Maven takes care of all the classpath stuff. (You would only need to add the oshi dependency, and its own pom tells Maven what other dependencies to get.). Your future self will thank you a million times over

is very apt
