如何读取 build.gradle 中 local.properties 中定义的属性

问题描述

我在local.properties中设置了sdk.dir和ndk.dir.

如何读取build.gradle文件中sdk.dir和ndk.dir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

你可以这样做:

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

如果您正在读取子项目 build.gradle 中的属性文件，请使用 project.rootProject:

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

如果属性文件在同一个子项目目录中，您可以只使用 project.

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