Answer 1

It turns out that this is a weird bug in the Gradle itself. I posted it on google forum and one of their coders gave me a solution and also put it up as an issue with the gradle team.

For the solution, you can clear your project cache (C:\Users\\.gradle\caches\transforms-1 ) and rebuild your project again and it will work fine. The gradle needs some artifacts to build which are stored in the cache memory. So if the gradle fails to build, the cache can be cleared which will prompt fresh downloading. You can be offline as long as all the artifacts you need have been downloaded in Gradle's cache (so don't delete the cache folder when offline!)
