Windows: "go get" Fails due to Path Length

[bgshacklett]

Summary:

It's currently not possible to build this project on Windows because of the length of some of the file names.

Steps to Reproduce

1. Configure a very short $env:GOPATH:
   PS>mkdir "C:\godir"
PS>$env:GOPATH = "C:\godir"
2. Attempt to "go get" the project:
   PS> go get github.com/awslabs/goformation

Expected Behavior

The package should be installed successfully

Actual Behavior

An error is returned:

go build github.com/awslabs/goformation/cloudformation: C:\Go\pkg\tool\windows_amd64\compile.exe: fork/exec C:\Go\pkg\tool\windows_amd64\compile.exe: The filename or extension is too long.

Environment

Windows

PS>[Environment]::OSVersion | fl

Platform      : Win32NT
ServicePack   :

VersionString : Microsoft Windows NT 10.0.14393.0

Go

PS>go version
go version go1.7.4 windows/amd64

Other Notes

I understand that this is technically an issue with the Go compiler as noted in golang/go#18468, but some of the file names in /cloudformation do seem to be excessively long. E.g.:

PS> gci .\cloudformation | Where-Object { $_.Name.Length -ge 80 } | select Name

I'm not familiar with go generate yet, but are there, perhaps, any flags which might allow for combining these types into a smaller set of files with shorter names?

[PaulMaddox]

I agree, the auto-generated names need rethinking. I'll take a look at this soon.
