在Eclipse中运行Java应用程序时如何避免全局扩展 [英] How to avoid glob expansion when running a Java app in Eclipse

问题描述

我遇到了Eclipse运行配置的特殊行为，这似乎是仅Windows的问题.假设我有一个Java应用程序，可以打印出命令行参数，如下所示:

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);
        }
    }
}

如果我为参数提供可以由shell扩展的通配符，则shell将对其进行扩展并将其提供给Java程序.这不足为奇.所以，如果我在命令提示符下这样做

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/*

程序将打印

test/foo.txt
test/bar.txt

其中foo.txt和bar.txt是目录"test"中的文件.

where foo.txt and bar.txt are files in the directory "test".

如果我在引号中加上通配符，则可以防止Shell扩展.* nix上的单引号，Windows上的双引号.因此，对于Windows，如果我在命令提示符下执行以下操作:

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/*"

该程序现在将打印

test/*

(不扩展).

但是，我发现Eclipse运行启动器中的引用似乎没有任何作用，并且该参数仍在扩展.如果我放

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/*"

在Eclipse运行启动器的程序参数部分中，并运行上面的类，我仍然得到

in the program argument section in the Eclipse run launcher, and run the above class, I still get

test/foo.txt
test/bar.txt

换句话说，当程序实际运行时，双引号似乎丢失了.这似乎仅在Windows中发生.

In other words, the double quotes seem to be lost when the program actually runs. This seems to happen only with Windows.

是否有一种方法可以防止Windows上的Eclipse运行启动器扩展全局扩展?

Is there a way to prevent the glob expansion with the Eclipse run launcher on Windows?

推荐答案

(.*)模式不会被eclipse扩展，并且仍然可以作为正则表达式使用.

The pattern (.*) will not be expanded by eclipse, and still works as a regex.
