## Create a self contained application specific tar bundle that can be
## brought to a system, unpacked and run.
##
## Requires that maven (mvn) be installed and on the PATH
##
## Run from the Application project's top level directory.

USAGE="usage: `basename $0` [--platform {java8|java7|android}] [--mainClass classname] [--appjar jarname] [--add csv-paths]"

## --platform the platform the app was built for (default: java8. options: java7, android)
##   This controls which Edgent platform jars are collected.
##   E.g., use "--platform java7" when the app is built using
##   the profile "-Pplatform-java7".
## --mainClass the main class name (default: com.mycompany.app.App)
## --appjar the application jar name (default: my-app-1.0-SNAPSHOT.jar)
## --add additional csv paths to include in the tarball (default: none)
##   Works best for paths in/under the App's project dir.
##   NOTE: anything in the App's src/main/resources dir generally
##   gets included in the App's jar.
