Sourcegraph factory examples from getting-started page works wrong

[musienko-maxim]

Reproduction Steps:

1. Go to the https://www.eclipse.org/che/getting-started/cloud/
2. Consuming Sourcegraph factory

Expected behavior: The project should be cloned and run.
Observed behavior: We have just empty folder with unknown project

Che version: 4.5.0
OS and version: Ubuntu OS 14.0
Chrome browser
Server location https://beta.codenvy.com
Additional information:

on sourcegraph when cloning the repository on my computer I have

$ git clone https://sourcegraph.com/sourcegraph/sourcegraph
Cloning into 'sourcegraph'...
remote: Counting objects: 148092, done.
remote: Compressing objects: 100% (60876/60876), done.
receiving objects:  12% (17772/148092), 2.75 MiB | 792.00 KiB/s

but if I try : import project

seems like a git/importer regression

Add "severity/blocker" not because the factory is not working, but because of the git/importer regression.

Can we have factory configuration or url to the project to be able to reproduce it on test environment?

Found the root of the problem: sourcegraph has client filtering by user-agent, so clients other than native git (we're using JGit now) receive 404 status. Example:
Not working:
curl -v "https://sourcegraph.com/sourcegraph/sourcegraph/info/refs?service=git-upload-pack
Working:
curl -v -H "User-Agent: git/2.1.0" "https://sourcegraph.com/sourcegraph/sourcegraph/info/refs?service=git-upload-pack"

So we have 2 options here:

1. Start endless discussion with sourcegraph to allow other clients too;
2. Just improve JGit client to always masquerade as native git client;

@slemeur @skabashnyuk @TylerJewell what do you prefer ?

[skabashnyuk]

Yes
Like egit https://github.com/eclipse/egit-github/blob/master/org.eclipse.egit.github.core/src/org/eclipse/egit/github/core/client/GitHubClient.java#L261

Fixed, thanks.
