In Maven projects, resources go to src/main/resources , not src/main/java by default.

So if you want to call Main.class.getResource("login.css") (relative path), then login.css has to be in the same package as Main, but in the resources directory.

If you would call someClassLoader.getResource("addStudent.css") or someClass.getResource("/addStudent.css") (absolute path), then addStudent.css has to be directly in src/main/resources .
