Had the same problem yesterday.
I solved it with download & installing manually the driver from the internet for my device.
Whats your device?
For Example:
My device is the MOTO G with Android 5.0.2
I just searching for the driver in google, installed it by the provider of my phone (Motorola) and tried the command line (gradlew installDebug) again.
worked for me. Hope it helps.
