Go on GAE: goapp get annoyances

[orhi...@gmail.com]

Hi,

I have several go projects which run on GAE. I wish to establish CI (or at least testing upon push to GitHub) with Travis for some these projects.

To begin with, I am trying to get Travis to execute my apps tests. To achieve this, my .travis file looks like this:

language: go

go:

  - "1.2.1"

install:

  - curl -O https://storage.googleapis.com/appengine-sdks/featured/go_appengine_sdk_linux_amd64-1.9.12.zip && unzip -q go_appengine_sdk_linux_amd64-1.9.12.zip

before_script: ./go_appengine/goapp get

script: ./go_appengine/goapp test

Problem is: the goapp get command returns status code 1 (which indicates error and thus will stop the build) because some GAE packages do not contain a "buildable go source". For example, anything that imports package "code.google.com/p/google-api-go-client/bigquery/v2" will get this error when you run:

goapp get

you get this message:

imports code.google.com/p/goauth2/appengine/serviceaccount: no buildable Go source files in /users/orcaman/src/code.google.com/p/goauth2/appengine/serviceaccount

Yet after performing the goapp get, everything basically works albeit the error (I guess this is because the goapp executable knows how to treat these GAE packages). so running: 

goapp test

for a testing code that uses code.google.com/p/goauth2/appengine/serviceaccount locally works perfectly. 

Any ideas on how to work around this to be be able to use Travis with GAE's Go?

Cheers,

Have you tried using `goapp get -d <blah>`?

Thanks for the tip David.

Unforunately adding the -d flag did not solve the issue:

16.97s$ ./go_appengine/goapp get -d
package code.google.com/p/goauth2/appengine/serviceaccount
	imports code.google.com/p/goauth2/appengine/serviceaccount
	imports code.google.com/p/goauth2/appengine/serviceaccount: no buildable Go source files in /home/travis/gopath/src/code.google.com/p/goauth2/appengine/serviceaccount
The command "./go_appengine/goapp get -d" failed and exited with 1 during .

I ended up writing the goapp get command as a shell script that always returns 0 for now. So in my .tavis file I have:

before_script: ./script/ci/get_deps.sh

and in the get_deps.sh I've got:

#!/bin/sh

echo "running goapp get to fetch dependencies..."

./go_appengine/goapp get

echo "dependencies fetched."

exit 0

This works as a workaround (because even though the script always returns 0, if the dep failed to be fetched, then the compilation would fail in the next step, so not a very silent failure) but obviously not ideal.
