That seems to be a common approach for upstream projects. I've seen many go
projects directed by a Makefile that doesn't set the GOPATH, so it requires
to hack our plugin. IMO, that means that the makefile is incomplete, but we
will need to deal with it. So far, I've solved it by making custom plugins
that combine two of snapcraft's plugins. That's not so nice for various
reasons. Sometimes you only need to add a command to an existing plugin,
and yet you have to copy it all. In the previous sprint we talked a little
about adding hooks, and making the plugins easier to extend, but that will
be a heavy burden to support in snapcraft.

We changed the python plugins completely in one of the recent releases.
using python-version: python2 now is the same as using plugin: python2.

Running snapcraft on your yaml, I actually get: Missing file:
Did you solve that somehow?
