Generated Spring pom.xml causes error "Error while fetching http://maven.apache.org/POM/4.0.0"

Question

(I am aware that there are similar questions - but having tried the solutions to them I am still stuck)

I am trying to use the Demo project from Spring and cannot get the generated pom.xml to work under IntelliJ, I tried the solution suggested by IntelliJ to resolve URI is not registered - but this simply causes the titular error.

At first I believed this to be a network error, but upon loading the webpage in a browser it 404s. This leads me to believe it is an issue with my project setup in some way.

I imported the project by opening the pom.xml in IntelliJ and then clicking 'Open as Project'.

My pom.xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>

</project>

None of the dependencies get loaded and I cannot for the life of me find a working solution to this.

I appreciate help, and understand if this is just a stupid question - I'm a stupid person

Make sure you have Maven bundled plugin enabled in Preferences |Plugins. If you are behind proxy - set up proxy settings in IDE: https://www.jetbrains.com/help/idea/settings-http-proxy.html

If you have Maven plugin enabled open project via File |New | Project from Existing Sources and select pom.xml file to import project from.
