> I noticed the other day that build/mvn will still use the system maven if "mvn" binary is installed. I think this was intentional to support just using zinc and using the system maven (and to match the semantics of sbt/sbt). It would be nice to have a flag that will force it to use the downloaded maven. I was thinking it could have a --force flag, and then it could swallow that flag and not pass it onto maven.
> This is useful in some cases like our test runners, where we want to coerce a specific version of maven is used.
