在eclipse中运行Java应用程序时如何避免glob扩展

问题描述

我遇到了Eclipse运行配置的特殊行为，它似乎是一个仅Windows的问题。假设我有一个Java应用程序打印出命令行参数，如下所示：

  public class WildCard {
 public static void main（String [] args）{
 for（String arg：args）{
 System.out.println（arg）; 
} 
} 
} 
  

如果我提供参数可以通过shell扩展的通配符，shell将扩展它并将其提供给Java程序。这并不奇怪所以，如果我在命令提示符下执行

  java WildCard test / * 
  / pre> 
 
 
程序将打印
  test / foo.txt 
 test / bar.txt 
  
其中foo.txt和bar.txt是目录test。
 
 
 
如果我用引号包围通配符参数，则可以防止Shell扩展; * nix上的单引号，Windows上的双引号。所以对于Windows，如果我在命令提示符下执行以下操作：
  java WildCardtest / *
  
该程序现在将打印
  test / * 
  
（无扩展）。
 
 
 
然而，我发现在Eclipse运行启动器中的引用似乎没有任何效果，而且参数仍然被扩展。如果我把
 test / *
  
在Eclipse运行启动器的程序参数部分，并运行上面的类，我仍然得到
 code> test / foo.txt 
 test / bar.txt 
  
在其他单词，当程序实际运行时，双引号似乎丢失。这似乎只发生在Windows下。
 
 
 
有没有办法通过Windows上的Eclipse运行启动程序阻止glob扩展？
解决方案
模式（。*）不会被eclipse扩展，仍然可以作为正则表达式。 p> 
I am running into a peculiar behavior of the Eclipse run configuration, and it appears to be a Windows-only problem. Suppose I have a Java app that prints out the command line arguments, like the following:
public class WildCard {
    public static void main(String[] args) {
        for (String arg: args) {
            System.out.println(arg);
        }
    }
}
If I provide argument with a wild card that can be expanded by the shell, the shell will expand it and give it to the Java program. That's no surprise. So, if I do on the command prompt
java WildCard test/*
the program will print
test/foo.txt
test/bar.txt
where foo.txt and bar.txt are files in the directory "test".
Shell expansions can be prevented if I surround the wildcard argument in quotes; single quotes on *nix, and double quotes on Windows. So for Windows, if I do the following on the command prompt:
java WildCard "test/*"
the program will now print
test/*
(no expansion).
However, what I find is that the quoting in the Eclipse run launcher seems to have no effect, and the argument is still expanded. If I put
"test/*"
in the program argument section in the Eclipse run launcher, and run the above class, I still get
test/foo.txt
test/bar.txt
In other words, the double quotes seem to be lost when the program actually runs. This seems to happen only with Windows.
Is there a way to prevent the glob expansion with the Eclipse run launcher on Windows?
 解决方案 
The pattern (.*) will not be expanded by eclipse, and still works as a regex.
