Package build is failing while packing .apk with keystore!

i have placed .keystore file on main directory i have no idea where should i place it.

last time when i build this project i got gradle error so i switched to ant… but right now i am getting ANT error…

full log: ant apk error - Pastebin.com gradle log: gradle error - Pastebin.com Any idea how to fix this?

Thank you
