---------------------------------
I notice the way to build option in description is :
{code:java}
Option option = Option.builder("foo").hasArg().build();
{code}
Maybe you can try this ,it will work in my test:
{code:java}
Option option = Option.builder("f").longOpt("foo").hasArg().build();
{code}
> DefaultParser fails to parse token "-S=V" if short option is longer than 1
> char

> Key: CLI-300
> URL: https://issues.apache.org/jira/browse/CLI-300
> Project: Commons CLI
> Issue Type: Bug
> Components: Parser
> Affects Versions: 1.4
> Environment: Windows 10, Java 11
> Reporter: Balz Guenat
> Priority: Major
>
> Assuming there is a short option with {{foo}} with one argument. Trying to
> parse a token like {{-foo=bar}} results in an UnrecognizedOptionException.
> The same scenario works fine if the short option is only one char long.
> The reason is an if-statement in {{DefaultParser.handleShortAndLongOption()}}
> (line 543 in v1.4), which checks {{opt.length() == 1}} before checking if the
> option exists. IMO, this check should instead be {{isShortOption(opt)}}.
> The below code demonstrates the issue.
> {{Options options = new Options();}}
> {{Option option = Option.builder("foo").hasArg().build();}}
> {{options.addOption(option);}}
> {{String[] args = new String[] \{"-foo=bar"};}}
> {{DefaultParser parser = new DefaultParser();}}
> {{CommandLine cmdLine = parser.parse(options, args);}}
> {{assertEquals("bar", cmdLine.getOptionValue("foo"));}}
