As the title shows, I can't find a reason why all the aar doesn't include the source code, See the all simple steps below that i had tried many times:

1.Download the AS. 2.New a project with the default configs. 3.Sync and waiting for finishing the build. 4.Edit a 'Text' and try to find some properties, then I was devastated ：）

I am sure that the net and the proxy are fine, and what can i do then?
