You need Java (1.6 or better) and a bash-like shell. To get started, some basic operating system tools (curl and zip). The spring command line interface can be installed like this

$ curl spring.cfapps.io/installer | bash

After running that command you should see a spring directory:

$ ./spring/bin/spring --help

usage: spring [--help] [--version] 
   <command> [<args>]
...

You could add that bin directory to your PATH (the examples below assume you did that).

If you don't have curl or zip you can probably get them (for Windoze users we recommend cygwin), or you can download the zip file and unpack it yourself.

Running the app

Use the spring command:

$ spring run app.groovy

Deploying to Cloud Foundry

To help avoid a timeout on startup you should upload all the dependencies. You can get those locally by running the app with --local:

$ spring run --local app.groovy

this will create a local directory grapes/ with all the jar dependencies. Then when you cf push they will be uploaded and used if the app is again launched with --local.
