Error 503 & aedeploy cloud app deploy cannot find package

[Gabor Lenard]

Hi,

I spent today trying to migrate my existing classic Go appengine app to the Flexible environment and am now completely stuck. I would be grateful if you could help.

• I have Python 2.7.10, Go 1.6.3 and App Engine SDK 1.9.40
• GOPATH is set to the root of the project directory, above src, so to the top of this: 
• The content of main.go:

  package main

  import (

  "google.golang.org/appengine"

  _ "modules/frontend"

  )

  func main() {

  appengine.Main()

  }

• The dev server (go app serve app.yaml) builds the source files alright but returns 503 Request Timed Out to all non-static files.
• aedeploy fails to deploy it (although the dir under /private/ seems to contain all files when I check it before hitting Return on “Do you want to continue"):
