Eclipse Java：根据构建配置定义最终变量

I want to have a final variable that is true when I run the Debug version of my project, and false when I run the Run version. I understand I can do this with build configurations but have no idea how to set this up in Eclipse. There don't appear to be any tutorials or questions on Stack Exchange regarding defining variables specifically.

我希望有一个最终变量，当我运行我的项目的Debug版本时是真的，而当我运行Run版本时是false。我知道我可以使用构建配置来做到这一点但不知道如何在Eclipse中进行设置。在Stack Exchange上似乎没有关于具体定义变量的任何教程或问题。

I'm compiling Java in Eclipse Classic 4.2, creating an Android app using the ADT plugin.

我正在Eclipse Classic 4.2中编译Java，使用ADT插件创建一个Android应用程序。

EDIT: Per @Xavi, I set up the following:

编辑：Per @Xavi，我设置了以下内容：

    try {
        String line = null;
        java.lang.Process p = Runtime.getRuntime().exec("getprop debugging");
        BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
        while ((line = input.readLine()) != null) {
            Log.d("Property:", line); //<-- Parse data here.
        }
        input.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

And in the "Additional Emulator Command Line Options" field of the Target tab of the Debug Configurations window, I've entered:

在Debug Configurations窗口的Target选项卡的“Additional Emulator Command Line Options”字段中，我输入了：

-prop debugging=true

Unfortunately it looks like this only works in emulator mode. It doesn't print anything when running on my phone. (It works fine running on an emulator.)

不幸的是，它看起来只适用于模拟器模式。在手机上运行时，它不会打印任何内容。（它在模拟器上运行良好。）

EDIT: Per @Sharks I found some links that seem relevant, but I don't know how to apply them to my situation:

If you're working in Eclipse with ADT then you can check variable BuildConfig.DEBUG. It's generated automatically and placed in the gen/<package>/BuildConfig.java:

如果您使用ADT在Eclipse中工作，那么您可以检查变量BuildConfig.DEBUG。它是自动生成的并放在gen / /BuildConfig.java中：

if (BuildConfig.DEBUG) {
   variable = true;
}
