Apache Commons CLI选项解析器可以忽略未知的命令行选项吗？

Apache Commons CLI选项解析器可以忽略未知的命令行选项吗？

这对我有用（也可以派生其他解析器）：

public class ExtendedGnuParser extends GnuParser {    private boolean ignoreUnrecognizedOption;    public ExtendedGnuParser(final boolean ignoreUnrecognizedOption) {        this.ignoreUnrecognizedOption = ignoreUnrecognizedOption;    }    @Override    protected void processOption(final String arg, final ListIterator iter) throws     ParseException {        boolean hasOption = getOptions().hasOption(arg);        if (hasOption || !ignoreUnrecognizedOption) { super.processOption(arg, iter);        }    }}
