We are using Jenkins in an enterprise environment that requires using a proxy server to connect to our github server.
Scanning the repo fails with:

Using the script console with
InetAddress dnsInetAddress = InetAddress.getByName 'github.example.com' //print IP address println dnsInetAddress.hostAddress
also fails.
But the Git plugin works just fine. Also using curl github.example.com works as expected.
So for me it looks, like the proxy setting is not properly respected. Or maybe it would be respected, but the previous lookup fails, b/c that's not possible with the proxy and the plugin terminates at that point.
Maybe someone could clarify that?
