// Hopefully, this is useful to someone else. Using the Slack Notification plugin it is trivially
// easy to send a Slack message from within a build pipeline. What may not be so easy is to send
// one from within a Groovy script build step inside a freestyle build, or from within another
// plugin. Personally, I hate having to reinvent the wheel, especially where making HTTP requests
// is concerned. So how do we leverage the Slack plugin for this scenario? Read on ...

// This is the main thing we need - the `StandardSlackService` class, exposed by the Slack
// Notification plugin.

// This is a simple usage case for retrieving a "secret text" or "token" credential
// from the global Jenkins credentials, and, if found, making it available as
// cleartext for use within a Groovy script or within a plugin. Obviously, this
// should NOT BE USED for mischevous purposes ...

// Cannot use System.getenv(keyName) nor System.getenv(). These do not include all of the build
// parameters, nor do they include Jenkins-specific environment values. The following will give
// access to all of that data, plus the system environment variables:

// Get access to the script binding context
def binding = this.getProperty('binding')

// Get the executing build
def build = binding.getVariable('build')
