Spring Security samples/xml/insecuremvc is empty

I am trying to code along with the Hello Spring MVC Security Java Config guide. However, the referenced directory doesn't include any project files. The guide states that I need to run the insecuremvc project to verify that it works. But, there is no project to run. I have tried using both the zip file linked in the guide, & this repo. The referenced directory has no project.

Hi, @KitPyles, sorry you are having trouble. The link you provided is for Spring Security 4.1.3, and so you'd find the samples in the 4.1.x branch.

That said, Spring Security 4 is no longer supported. Please consider using the Spring Security Samples project instead, which demonstrate Spring Security 5 and 6.
