Gradle sync failed

15:29 Gradle sync started
15:30 Gradle sync failed: For input string: ""

whats wrong with this:

static def gitVersionCode() {
def process = "git rev-list --count HEAD".execute()
return process.text.toInteger()
}

Then git is probably not initialised in your project folder. What do you see when you run git rev-list --count HEAD from your project folder?
