Go-importpath Question - not a github URL

Hi there, I’m building a snap for shfmt, and traditionally you can install the app with go get -u mvdan.cc/sh/cmd/shfmt. But for some reason when I use the go plugin and set go-importpath: mvdan.cc/sh/cmd/shfmt - the package cannot be found. But go get works fine.

My current working snap is just using the dump plugin to wget the compiled binary from github, but was investigating doing it properly. I’m also working with the developer to see what his interest is, and how they would like to move forward (hoping upstream might take over once built).
