[SyncEvolution] “usename=goa:username@gmail.com” doesn't work on Ubuntu Gnome (Vivid)

Hi, When I try syncevolution --print-databases \ backend=carddav \ username=goa:myusername@gmail.com \ syncURL=https://www.googleapis.com/.well-known/carddav it throws me “unknown identity provider 'goa' in 'goa:myusername@gmail.com'” AFAIK goa integration is enabled by default. So it should work with it. However, in Unity, if I install 'syncevolution-provider-uoa', it works fine with Ubuntu online online accounts i.e. 'username=uoa:11, google-contacts'. Also it doesn't seem to work with oauth2 either. "username=oauth2:{'TokenHost': 'https://accounts.google.com', 'TokenPath': '/o/oauth2/token', 'Scope': 'https://www.googleapis.com/auth/carddav https://www.googleapis.com/auth/calendar';, 'ClientID': '923794261470.apps.googleusercontent.com', 'ClientSecret': 'SlVBAcxamM0TBPlvX2c1zbEY'}" "password=1/CxmvbGWTmgyKTlv**************" [refresh token extracted from seahorse] syncevolution --print-databases \ backend=carddav \ username=$username \ password=$password \ syncURL=https://www.googleapis.com/.well-known/carddav gives “[ERROR 00:00:00] unknown identity provider 'oauth2' in 'oauth2:{'TokenHost': 'h....................” why? . Thanks & Merry Christmas.
