Maven 1.x Eclipse Plugin

Question

I've got the challenge to maintain a project setup using Maven 1.1. It's some kind of a legacy project, so updating is not an option, at least not currently :-/

So my question is: how do I enable my Eclipse to work with Maven 1? IIRC there were at least 2 Plugins available in the early ages of Maven projects. As far as I can see, the up-to-date plugins are unable to process such ancient projects, are they?

Thanks in advance!
