java - 如何在 Scala 中消除带可变参数和不带可变参数的方法之间的歧义

Question

我正在尝试使用 Scala 的 java jcommander 库。 java JCommander 类有多个构造函数:

 public JCommander(Object object)  
 public JCommander(Object object, ResourceBundle bundle, String... args)   
 public JCommander(Object object, String... args)   

我想调用第一个采用 no 可变参数的构造函数。我试过了:

jCommander = new JCommander(cmdLineArgs)

我得到错误:

error: ambiguous reference to overloaded definition,
both constructor JCommander in class JCommander of type (x$1: Any,x$2: <repeated...>[java.lang.String])com.beust.jcommander.JCommander
and  constructor JCommander in class JCommander of type (x$1: Any)com.beust.jcommander.JCommander
match argument types (com.lasic.CommandLineArgs) and expected result type com.beust.jcommander.JCommander
jCommander = new JCommander(cmdLineArgs)

我也尝试过使用命名参数，但得到了相同的结果:

jCommander = new JCommander(`object` = cmdLineArgs)

如何告诉 Scala 我要调用不带可变参数的构造函数？

我使用的是 Scala 2.8.0。

抱歉，我现在意识到这是一个已知的 Java 互操作性问题。见 this question和 the ticket .我所知道的唯一解决方法是创建一个小型 Java 类来消除这些调用的歧义。
