I am trying to deploy my first app to the Google App Engine but i am encountering the following problem:
Could not sign in to Google in eclipse. It says: "Could not sign in. Make sure that you have entered the correct verification code". I do not have a two step verification with the account i am trying to sign in. I also tried to change the proxy settings under the Windows->Preferences->Network Connections but that also didn't work.(I am in a corporate network)
I could run the application correctly on the local machine.
I also tried deploying it through command line using : ...\appcfg.cmd update war . This gives the following message in the log file:
Unable to update:

Can anybody please help me with this?
For me, it was because of Kaspersky Internet Security 2015. Just pause Kaspersky protection until you deploy your war/ear, or just turn off "Web Anti-Virus" module.
