build.gradle(项目)和build.gradle(模块)的区别 [英] Difference between build.gradle (Project) and build.gradle (Module)

问题描述

我正在尝试将 Android 异步 Http 客户端的依赖项添加到我的项目中.所以项目中有两个build.gradle文件.

I am trying to add a dependency of Android Asynchronous Http Client into my project. So there are two build.gradle files in the project.

根据我的理解，有不同类型的依赖:

As per my understanding, there are different kind of dependencies:

1. 在 build.gradle (Project:My-app) 的根级别定义的一个
2. build.gradle (Project:My-app) 的构建脚本中的一个
3. 另一个是 build.gradle (Modules:app)

1. One which defined on the root level of build.gradle (Project:My-app)
2. One inside the buildscript of the build.gradle (Project:My-app)
3. Another is build.gradle (Modules:app)

这个问题是关于 buildScript 依赖的仓库，解释一下前两种类型.

This question is about repositories for dependencies of the buildScript, explain a bit about first two types.

还有 build.gradle (Project:My-app) 说

Also build.gradle (Project:My-app) says

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files

所以我猜Android Asynchronous Http Client的依赖代码应该加在build.gradle(Module:app)中.

So I guess the dependency code of Android Asynchronous Http Client should be added in build.gradle (Module:app).

它们是如何组合在一起的?

How does it all fit together?

推荐答案

build.gradle (Project:My-app)

build.gradle (Project:My-app)

顶级构建文件，您可以在其中添加常见的配置选项所有子项目/模块.

Top-level build file where you can add configuration options common to all sub-projects/modules.

每个项目都包含一个顶级 Gradle 文件.它通常包含所有模块的通用配置.无论这个顶级 Gradle 文件中包含什么，它都会影响所有模块.

Each project contains a top-level Gradle file. It usually contains common configurations for all modules. Whatever is included in this top-level Gradle gile, it will affect all modules.

示例:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-alpha3'

        //Maven plugin
        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle (Module:app)

build.gradle (Module:app)

特定模块的构建文件(在其中添加依赖项、签名配置、构建类型、风格等)

所有模块都有一个特定的 Gradle 文件.无论在这个 gradle 文件中包含什么，它只会影响包含在其中的 module.

All modules have a specific Gradle file. Whatever is included in this gradle file, it will only affect the module that is included on.

示例:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.hrskrs.gesturefun"
        minSdkVersion 10
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            zipAlignEnabled true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            debuggable true
            zipAlignEnabled true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile project(':gesture-fun')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.jakewharton:butterknife:7.0.1'
}
