Python Question

golang appengine - filename too long

I developed an appengine application in GO and now I tried to use the androidpublisher api. For this I need many dependencies like:


  • github.com/google/google-api-go-client

  • github.com/golang/oauth2

  • google.golang.org/appengine

  • google.golang.org/appengine/urlfetch



I tried to setup oauth2 authentication for google-api-go-client according to the example in https://github.com/golang/oauth2

Everything looks fine but I can't run the app-server anymore on my windows development machine. It complains about too long filenames:

I think my
GOPATH
is set up wrong so he gives all gofiles as argument to
go-app-builder.exe
.

My project is under
C:\Users\me\project\
that's where the gopath points to and were I'm standing when I type:

goapp.bat serve .


Can someone help to fix this problem? Thank you.

EDIT

My project structure is like this:
How should i set my GOPATH?

GOPATH
$GOPATH
app.yaml
cron.yaml
pkg
src
testapp
app.go
golang.org
x
oauth2


Edit 2

I tried to move my GOPATH to project-root-dir/gopath but now i get this error message:

for all non german users it complains about a wrong parameter

Answer

I solved the problem by setting my GOPATH.

It's set now like this:

GOPATH=C:\Users\me\development\appengine\gopath;C:\Users\me\project

Now everything works find and the uploaded file is much smaller now. 2MB vs. 11MB.

Thanks for the tip.
