org.gradle.initialization.CommandLineParser

A command-line parser which supports a command/subcommand style command-line interface. Supports the following syntax:

 <option>* (<subcommand> <subcommand-option>*)

Short options are a '-' followed by a single character. For example: {@code -a}.
Long options are '--' followed by multiple characters. For example: {@code --long-option}.
Options can take arguments. The argument follows the option. For example: {@code -a arg} or {@code --longarg}.
Arguments can be attached to the option using '='. For example: {@code -a=arg} or {@code --long=arg}.
Arguments can be attached to short options. For example: {@code -aarg}.
Short options can be combined. For example {@code -ab} is equivalent to {@code -a -b}.
Anything else is treated as an extra argument. This includes a single {@code -} character.
'--' indicates the end of the options. Anything following is not parsed and is treated as extra arguments.
The parser is forgiving, and allows '--' to be used with short options and '-' to be used with long options.
The set of options must be known at parse time. Subcommands and their options do not need to be known at parse time. Use {@link ParsedCommandLine#getExtraArguments()} to obtain the non-option command-line arguments.
