在eclipse中设置引用其他环境变量的环境变量 [英] Setting environment variables in eclipse that references other environment variables

问题描述

我有一个Eclipse程序设置的Eclipse Helios。我试图创建两个环境变量

ReportingManagerHome = C：\rp

ReportingManagerConfig = $ {ReportingManagerHome} \config

然后我运行我的程序

System.out.println（System.getenv（ReportingManagerConfig））;

Eclipse甚至不调用java编译器。它抛出一个弹出窗口，其中没有定义环境变量ReportingManagerHome的错误。我明白，由于java编译器尚未被调用，技术上Eclipse是正确的。

现在我如何解决这个问题，以便我可以在Eclipse中定义级联环境变量？

解决方案

它不会从启动配置递归展开环境变量。

即使使用 $ {env：VAR} 从您的eclipse进程的环境变量中取出，而不是从当前的启动配置。

最可靠的方法是转到首选项>运行/调试>字符串替换并在其中定义一个eclipse变量。

然后在启动配置中定义环境变量：

  ReportingManagerHome = $ {RMH} 
 ReportingManagerConfig = $ {RMH} \config 
  

I have Eclipse Helios with a java program set up. I'm attempting to create two environment variables

ReportingManagerHome=C:\rp
ReportingManagerConfig=${ReportingManagerHome}\config

I then run my program with

System.out.println(System.getenv("ReportingManagerConfig"));

Eclipse doesn't even call the java compiler. It throws up a pop up window with the error that environment variable ReportingManagerHome is not defined. I understand that since the java compiler has yet to be called, technically Eclipse is correct.

Now how do I work around this so that I can define cascading environment variables in Eclipse?

解决方案

It won't recursively expand environment variables from the launch config.

Even using ${env:VAR} takes it from the environment variables from your eclipse process, not from your current launch config.

The most reliable way to do it is to go to Preferences>Run/Debug>String Substitution and define an eclipse variable there.

Then define the environment variables in your launch config:

ReportingManagerHome=${RMH}
ReportingManagerConfig=${RMH}\config
