将环境变量传递给gradle.properties [英] Pass env variables to gradle.properties

问题描述

我有一个这样的属性集:

I have a property set like this:

url=localhost:3206

有没有一种方法可以像下面这样指定:

Is there a way to specifiy this like below instead:

url=${hostname}:3206

推荐答案

我不认为gradle.properties支持插值.但是，我建议您采用另一种方法来完成此任务:

I don't think gradle.properties supports interpolation. However, I would suggest an alternative means to accomplishing this:

在gradle.properties中具有以下内容:

Have the following in your gradle.properties:

hostname=localhost
port=3206

在build.gradle中的某处，执行以下操作:

Somewhere in your build.gradle, do the following:

beforeEvaluate {
  ext.url = "$hostname:$port"
}

要配置主机名或端口，您需要几个选项.我更喜欢使用项目环境变量，例如:

To configure the hostname or port, you have several options. I prefer using project environmental variables like:

ORG_GRADLE_PROJECT_hostname=0.0.0.0
ORG_GRADLE_PROJECT_port=4321

现在，当您运行项目时，gradle将拾取环境变量，并用这些变量替换gradle.properties中的那些变量.

Now when you run your project, gradle will pick up the environmental variables and replace the ones in gradle.properties with these.
