How to refresh external Jars in Eclipse project (Java)?

I have a Java project in Eclipse which includes a couple of external jar files. These external jar files are being rebuilt through a different process (not Eclipse, Ant). Those changes are not being reflected on the Eclipse project even if I refresh the project. If I close the project and reopen, it works.

Any suggestions on how I could expedite the project without having to close and reopen? Thanks.

How do I refresh a project in Eclipse?

When a new file is created in Eclipse you might need to refresh the Eclipse project to see the new file. This refresh process can take place automatically. To set auto-refresh, go to window → preferences → general → workspace and check the "Refresh using native hooks or polling" check-box.

Try right click on the project and select refresh. If that does not work, go to the Project menu, clean, and check your project.
