NoClassDefFoundError when trying to access Selenium JAR files on build path. Source not found

Question

I'm new to Selenium. The class file is saying that "The JAR file [my path] has no source attachment."

I recently downloaded Selenium and I'm trying to run with Java. I extracted the files to a folder. I added the all JAR files including the ones inside the lib folder to my Modulepath by right clicking on the project -> Properties and clicking "Add External JARs" on the Build Path. Then I ran the following program . I've watched about every youtube video I can on the topic and am about to try on a different IDE. Any help would be much appreciated. Thanks
