apply plugin: 'com.android.application'
apply plugin: 'hockeyApp'

hockeyapp {
    apiToken = "YOUR_HOCKEY_APP_TOKEN"
    notify = 1 //to notify all testers that can install this app
    status = 2 //to make the version available for download
    tags = 'your-project-tag'
    notes = getUploadNotesParam()
}

============

//Gradle then gets additional tasks like:
//HockeyApp tasks
//---------------
//uploadDebugToHockeyApp - Upload 'debug' to HockeyApp
//uploadReleaseToHockeyApp - Upload 'release' to HockeyApp

//FurtherUsage from command line will be like:
//./gradlew clean build uploadDebugToHockeyApp
//./gradlew clean build uploadDebugToHockeyApp -PuploadNotes="Foo Bar"
