//   - Add a `CertificateValidityPeriod` and `CACertificateValidityPeriod` fields to `ClusterConfiguration`. These fields
//     can be used to control the validity period of certificates generated by kubeadm during sub-commands such as `init`,
//     `join`, `upgrade` and `certs`. Default values continue to be 1 year for non-CA certificates and 10 years for CA
//     certificates. Only non-CA certificates continue to be renewable by `kubeadm certs renew`.

@REM Required ENV vars:
@REM JAVA_HOME - location of a JDK home dir
@REM
@REM Optional ENV vars
@REM M2_HOME - location of maven2's installed home dir
@REM MAVEN_BATCH_ECHO - set to 'on' to enable the echoing of the batch commands
@REM MAVEN_BATCH_PAUSE - set to 'on' to wait for a keystroke before ending
@REM MAVEN_OPTS - parameters passed to the Java VM when running Maven
@REM     e.g. to debug Maven itself, use

	Timeout            int
	Symbolize          string
	HTTPHostport       string
	HTTPDisableBrowser bool
	Comment            string

// parseFlags parses the command lines through the specified flags package

	flag := o.Flagset
	// Comparisons.

	// cause the command to return an error with this exit code set.
	ReturnCode int
}

// ScriptCommands configures fe, the FakeExec, to have a pre-configured list of
// commands to expect. Calling more commands using fe than those scripted will
// result in a panic. By default, the fe does not enforce command argument checking

Let's assume the following use-case to illustrate the use of the command line options.
You would like to generate the Wrapper with version {gradleVersion} and use the `-all` distribution to enable your IDE to enable code-completion and being able to navigate to the Gradle source code.

The following command-line execution captures those requirements:
