This is all near and dear to my heart. First, some terminology clearing up: the Maven internals rely on a JSR-330 implementation (javax.inject.*), not CDI (javax.enterprise.inject.*). CDI is a JSR-330 implementation, but so is Guice, HK2, etc. I believe that the internals of Maven rely on Guice, but as Robert says, if you're not rebuilding the innards of Maven then using the facilities of JSR-330 make the code really simple.
I did actually put parts of Maven in CDI ( https://microbean.github.io/microbean-maven-cdi/). You may find some of the implementation classes in question that you need in there.
