As you know, starting from 15 January 2020 Maven central repo requires HTTPS-only access. One of our projects is using Ant and Maven Ant Tasks (dependency management only). Yes, I know it's deprecated, but what is the other option for using pom.xml in old ant builds?
Looks like the Maven Ant Tasks have a bug if the dependency tree contains a link to pom, it always will be accessed through HTTP (despite locally configured https://repo.maven.apache.org/maven2).
Any ideas on how to workaround the bug?
P.S. Yes, that is working configuration (i.e. worked through HTTP) and pom file exists with the correct parameters.

A strange solution that works for us:
<artifact:dependencies filesetid="maven.classpath" settingsfile="settings.xml>
<pom file="../pom.xml" />
</artifact:dependencies>
And settings.xml contains https mirror to repo
<settings>
<mirrors>
<mirror>
<id>central.mirror</id>
<url>https://repo1.maven.org/maven2/</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
</settings>
