Basically, this follows a pattern for a work project that has a few constraints, but I don’t think they are unusual or unexpected:

1. A few apps (device, cloud, etc) doing things independently, but as part of one overall project, and sharing some project-specific packages
2. Using dep for dependency management (that can flex)
3. Other languages besides Go (so I’m limited in what I can drop into the top-level src/, but can put what I want in my per-app dirs, and Go-specific libs/)
4. At some point soon, an overall build/CI process will run against the whole repo to build the apps (Go and non-Go)

The primary issue is that the shared dependencies aren’t recognized as being the same package (and exporting identical types) because they get interpreted as being from their respective vendor dirs.

Some options I’ve considered, that either have not worked, or I don’t know how to do:

• Don’t vendor the libs. This is what the general recommendation seems to be, but I can’t get them to build without their dependencies (and I want to run unit tests, etc)
• Build the libs as binaries that link into the apps. No idea how to do this
• Treat the libs as external dependencies, even tho they are in the same repo. I tried some naive approaches to including them in the apps’ Gopkg.toml, to no avail.

Some other points: the example has just one app, but the real project has three so far. It uses Ginkgo for unit testing, which sets flags in it’s init(), so yeah, that’s a problem. However, I assume that the solution to getting github.com/google/uuid to work will generalize. I chose that for the example, because Google.
