从Android Studio gradle构建访问环境变量 [英] Access to environment variables from Android Studio gradle build

问题描述

在我的Android Gradle构建中，我需要访问从 .bash.profile 设置的环境变量。当我从命令行构建时，它工作正常 - Gradle脚本可以看到所有的变量。

但是，当我尝试从Android Studio运行我的构建 - 我没有我的环境变量。

1）通过〜/ .bash.profile设置自定义环境变量

/ code>：

  export MY_CUSTOM_VAR ='Hello World'
  / pre> 
 
 
 2）在 build.gradle 中创建打印此环境变量的任务：
  task printVar<< {
 println System.getenv（MY_CUSTOM_VAR）
} 
  
 3）从命令行执行 printVar 。输出正确 - 设置env变量：
 
 
 
输出： Hello World  
 
 
 
 4）从Android Studio执行 printVar 。环境变量未设置。输出为空
 
 
 
常识告诉我，通过执行导出MY_CUSTOM_VAR ='Hello World'我只是使这个变量可用于shell进程（及其子进程）。如果我从命令行启动我的Android Studio（因此它会继承我的环境）这将是可能的工作。但是，由于我从Dock启动了Android Studio（我在Mac上是这样） - 它有自己的环境，不了解我的〜/ .bash.profile 。
 
 
 
有没有办法可以将自定义环境变量填充到Android Studio？
解决方案
在此找到答案：
  Mac中的环境变量OS X  
 
 
 
本质上，您还需要通过<$ c设置 launchd 使用的环境变量$ c> launchctl   - 这种环境变量将可用于从MacOS UI启动的任何内容
 
 
 
所以我修改了我的 〜/ .bash_profile 如下：
  export MY_CUSTOM_VAR ='Hello World'
 launchctl setenv MY_CUSTOM_VAR $ MY_CUSTOM_VAR 
  
 
In my Android Gradle build I need to get access to environment variables I set from .bash.profile. It works fine when I build from command line - Gradle script can see all the variables. 

However, when I try to run my build from Android Studio - I don't have my environment variables anymore.

Here is a rough picture of what I'm facing:

1) Set custom environment variable via ~/.bash.profile:
export MY_CUSTOM_VAR='Hello World'
2) In build.gradle create task which prints this environment variable:
task printVar << {
    println System.getenv("MY_CUSTOM_VAR")
}
3) execute printVar from command line. Output is correct - env variable is set:

output: Hello World

4) execute printVar from Android Studio. Environment variable is not set. Output is empty

Common sense tells me that by doing export MY_CUSTOM_VAR='Hello World' I just make this variable available to shell process (and its subprocesses). And it would probable work if I launch my Android Studio from command line (so it would inherit my environment). But since I launch Android Studio from dock (i'm on Mac by the way) - it has its own environment which doesn't have any idea about my ~/.bash.profile.

Is there any way I can populate custom environment variables to Android Studio?
解决方案
Found an answer here:
Environment variables in Mac OS X

Essentially, you need to also set environment variables used by launchd via launchctl - this way environment variable will be available for anything launched from MacOS UI

So I modified my ~/.bash_profile as follows:
export MY_CUSTOM_VAR='Hello World'
launchctl setenv MY_CUSTOM_VAR $MY_CUSTOM_VAR
