Snapcraft crashes after defining a local source for a golang project

[XiaoGuo, Liu]

I have a simple snappy project at

https://github.com/liu-xiao-guo/go-webserver

If I do not want to use "source: git://github.com/liu-xiao-guo/golang-http" in the snapcraft.yaml to compile the go. Instead, I want to make the source code locally. Then I make the following change to my snapcraft.yaml:

name: go-webserver
vendor: XiaoGuo, Liu <email address hidden>
icon: go.png
version: 1.0.7
summary: Go webserver
description: This is a simple go webserver. It is a service

services:
  webserver:
    description: "Go websever"
    start: bin/golang-http
    caps:
     - network-client
     - network-service

parts:
  webserver:
    plugin: go
    source: ./src/golang-http

Inside the golang-http, it has only one file named "main.go", which can be found at:

https://github.com/liu-xiao-guo/golang-http/blob/master/main.go

liuxg@liuxg:~$ snapcraft version
snapcraft (0.4).
Run "snapcraft help" to get started.

I think this is a valid use case, so removing the dup.

lets say you have a go project in a local dir, you don't want to go get it . Or, lets say you put your snapcraft.yaml in github, in the same repo as your go code, so github clone already downloaded the code, you don't want go get to bring it too. And maybe you cloned and checked out a branch, not master...

Can you try master from https://github.com/ubuntu-core/snapcraft.git ?

[XiaoGuo, Liu (liu-xiao-guo)]

Thanks, it works in the 0.5 version!

Fixed in https://github.com/ubuntu-core/snapcraft/pull/97
I followed liux' instructions and confirm that the snap can be created with the local source.
