Ant error: SDK does not have any Build Tools installed

[NumesSanguis]

Not sure if related to ant or .ttf file. I deleted the previous .buildozer folder in my app folder and the .buildozer in my Home directory and ran the command: buildozer debug
It might be related to: #208
This is the error log:
