Apache Commons CLI

The Apache Commons CLI projects features a complex set of controls that allow developers to interact with the user's terminal, supplying him with a set of commands that are then translated into actions inside the application/software.

Commons CLI can parse commands and their arguments/parameters from the user's terminal while also giving him immediate feedback for whatever he typed.

The library can be used for building both CLI command centers and CLI help guides, supporting a wide range of command-line options.

These include:
- POSIX like options
- GNU like long options
- Java like properties
- Short options with value attached
- Long options with single hyphen

• A major regression introduced in CLI 1.1 that prevented the usage of repeated options has been fixed.
• Several parser issues have been fixed, especially with the PosixParser.
• HelpFormatter now wraps the lines properly
• The ordering of the option in the help message can now be defined.
• Various API enhancements (improved exceptions, serializable classes)
