Benedikt Ritter commented on CLI-253:
-------------------------------------
Changing the test to use DefaultParser fixes the problem. Please use
DefaultParser instead of PosixParser.
> Unrecognized option: --null

> groovy project uses commons-cli in following way:
>
> {code:java}
> options.addOption(OptionBuilder.hasArg().withArgName("path").withDescription("Specify
> where to find the class files - must be first
> argument").create("classpath"));
> options.addOption(OptionBuilder.withLongOpt("classpath").hasArg().withArgName("path").withDescription("Aliases
> for '-classpath'").create("cp"));
> {code}
> https://github.com/groovy/groovy-core/blob/GROOVY_1_8_X/src/main/org/codehaus/groovy/tools/FileSystemCompiler.java#L297-L298
> When called with long option "--classpath ...", it throws exception:
> org.apache.commons.cli.UnrecognizedOptionException: Unrecognized option:
> --null
> Same code works fine with commons-cli 1.2.
