如何阅读在build.gradle local.properties定义的属性 [英] How do i read properties defined in local.properties in build.gradle

问题描述

我已经设置sdk.dir和ndk.dir在local.properties。

I have set sdk.dir and ndk.dir in local.properties.

我要如何阅读sdk.dir和ndk.dir在build.gradle文件中定义的值？

How do i read the values defined in sdk.dir and ndk.dir in the build.gradle file?

推荐答案

您可以做，在这种方式：

You can do that in this way:

Properties properties = new Properties()
properties.load(project.rootProject.file('local.properties').newDataInputStream())
def sdkDir = properties.getProperty('sdk.dir')
def ndkDir = properties.getProperty('ndk.dir')

使用 project.rootProject 如果你正在阅读的一个子项目 build.gradle 属性文件：

Use project.rootProject if you are reading the properties file in a sub-project build.gradle:

.
├── app
│   ├── build.gradle <-- You are reading the local.properties in this gradle build file
│   └── src
├── build.gradle
├── gradle
├── gradlew
├── gradlew.bat
├── settings.gradle
└── local.properties

在情况下，属性文件是在同一个子项目目录，你可以只使用项目。

In case the properties file is in the same sub-project directory you can use just project.
