Can I import a package from a git submodule?

[cpu...@gmail.com]

Consider this layout:

• Repo A contains module foo
• Repo B contains module bar (of course ;)
• Repo B is added as submodule to repo A at /baz

I was expecting that I can 

import "foo/baz/bar"

in repo A, but that leads to error ("no required module provides package...").

Shouldn't this work as the import path is a perfectly valid import path inside module foo?

Cheers,

Andi

AIUI, if you nest modules (that is, a subdirectory of a module containing a directory with its own `go.mod`), the "inner" module is not considered part of the "outer" module. In particular, it would also not be included in the module zip (which is the primary way modules are distributed - *not* as repositories).

So, AIUI, `foo/baz/bar` is technically a valid import path, but it's not "inside" module `foo`, so to speak.

It's really annoying to deal with when you have private repositories, but try to simply `import RepoB/bar` from ModuleA, and don't bother with the submodule stuff. Module SHAs will replicate submodule functionality in a way that's more compatible with the language.
