Not creating JAR file

I've been using IntelliJ for the past day and wasn't having any issues, however something seems to have changed and now I can't create JAR files when building a project.

Artifacts have been set up in Project Structure, and when clicking on build project I'm not getting any errors, but the JAR file just isn't being created.

I've already tried double checking the settings in Project Structure but nothing seemed to be an issue.  I've created a new project and even trying to build something incredibly basic isn't doing anything.

Any help would be appreciated.
