Why does Hybris ship insecure http maven repository URL? And why can't we override it?

Question

In apache-ant/lib/libraries.properties

m2.repo=http://repo1.maven.org/maven2/

What is the point of shipping Hybris with http URL?
It cannot be accessed in the first place, let alone used for downloading.
Ideally, it should be an https URL.

m2.repo=https://repo1.maven.org/maven2/

I tried overriding it by redeclaring this property in local.properties. When that did not pick the new value, I changed it to https in apache-ant/lib/libraries.properties, but it is still picking http. How to override this property?

You can override this by setting up your $HOME/.m2/settings.xml file.

For example:

    <?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
