Gradle Keystore password not set but JAR file is built

[paolantoni]

Running application in development mode " touching" the keystore file without setting the keystore passowrd does not prevent from downloading the android sdk to build the jar file, why?
The documentation shows:
"To run in development without support for JAR file building:

touch gradle/data/driver.keystore
(If you just want to install the DRIVER web interface, do this. You can add Android integration later.)
"
However you can't run successfully the playbook through vagrant in production without setting the keystore password.
