如何使用 Picocli 在不指定索引的情况下传递参数

问：

我正在尝试使用 Picocli 创建一个接受可选选项和参数的 cli 程序。我希望参数始终位于传递参数的末尾，但是我不知道如何设置它。 当我尝试以下操作时，这些选项也被解析为文件名。有没有办法解决它？

public class WordCount implements Runnable {

@Parameters(index="*", arity = "1..*", description= "The file to count")
public List<String> filenames;

@Option(names = {"-c", "--countBytes"}, description = "Count the number of Bytes in the file")
private Boolean countBytes= false;

@Option(names= {"-w", "countWords"}, description = "Count the number of Words in the file")
private Boolean countWords = false;

@Option(names = {"-l", "--countLines"}, description = "Count the number of lines in the file")
private Boolean countLines =false;

@Option(names = {"-m", "--countCharacters"}, description = "Count the number of characters in the file")
private Boolean countCharacters =false;
