问题描述

将 Eclipse 项目导入 Android Studio 后，我看到两个 build.gradle 文件:

After having imported an Eclipse project into Android Studio, I see two build.gradle files:

1 - <PROJECT_ROOT>uild.gradle
2 - <PROJECT_ROOT>appuild.gradle

第一个版本较短，第二个版本包含compileSdkVersion等的定义.

The first version is shorter, the second version contains definitions for compileSdkVersion, etc.

拥有两个独立文件的目的是什么?是否有单独的构建任务?

What is the purpose behind having two separate files? Are there separate build tasks?

推荐答案

<PROJECT_ROOT>appuild.gradle 专用于 app 模块.

<PROJECT_ROOT>uild.gradle 是一个顶级构建文件"，您可以在其中添加所有子项目/模块通用的配置选项.

<PROJECT_ROOT>uild.gradle is a "Top-level build file" where you can add configuration options common to all sub-projects/modules.

如果您在项目中使用另一个模块，作为本地库，您将拥有另一个 build.gradle 文件:<PROJECT_ROOT>moduleuild.gradle

If you use another module in your project, as a local library you would have another build.gradle file: <PROJECT_ROOT>moduleuild.gradle

对于顶级文件中的 example，您可以指定以下常用属性:

For example in your top level file you can specify these common properties:

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
    }
}

ext {
    compileSdkVersion = 23
    buildToolsVersion = "23.0.1"
}

在你的 appuild.gradle

apply plugin: 'com.android.application'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion
}
