go get fails

[chris-edwards-pub]

I am having an issue with "go get github.com/coredns/alternate" It looks like its failing to find the proxy plugin.

github.com/coredns/coredns/plugin/pkg/proxy: cannot find module providing package github.com/coredns/coredns/plugin/pkg/proxy

It started working fine when I did the "go get github.com/coredns/alternate" before "go get github.com/cloud66-oss/coredns_mysql".

Getting the same error, I don't have any plugin to add before it or after it

@SuperQ , yes I've added alternate before forward only

I have cut v0.2.0 with updated Go module dependencies. Please try go generate again. Also make sure your source for CoreDNS is up to date with v1.11.1.
