-----------------------------------

             Summary: replace JCommander with picocli
                 Key: LOG4J2-2011
                 URL: https://issues.apache.org/jira/browse/LOG4J2-2011
             Project: Log4j 2
          Issue Type: Improvement
          Components: Core, Servers
    Affects Versions: 2.8.2
            Reporter: Remko Popma
            Assignee: Remko Popma
             Fix For: 2.9


As discussed in the mailing list, replace uses of JCommander with [picocli|https://github.com/remkop/picocli] to get

* customizable usage help
* usage help with ANSI colors
* better support for positional parameters (so we can use positional parameters for mandatory arguments and options for optional arguments)
* include picocli as source so users can run these applications without requiring an external dependency

Candidates for usage are:

*log4j-core*

* CustomLoggerGenerator
* ExtendedLoggerGenerator
* Generate
* PluginManager

*log4j-jmx-gui*
* ClientGui

*log4j-1.2-api*
* Log4j1ConfigurationConverter

*logging-log4j-tools/log4j-server*
* AbstractSocketServer
* TcpSocketServer
