'Unable to import and use org.apache.commons even though it is added to classpath

As the title suggests I am unable to use the apache commons library in Jgrasp even though the jar file has been added to my classpath. Attached are screenshots. This really doesn't make any sense to me as I've followed all the advice i could find an nothing seemed to have worked.

Classpath: Classpath

imports: My imports

Output: Error output
