欢迎Follow我的, 关注我的.
最近经常有人问我, 如何管理gradle版本, 我来统一讲解这些小技巧.
随着开发的成熟, 模块越来越多, 为了开发稳定的程序, 引入的库也随之增加, 如何确保所有项目使用相同的编译版本he库版本呢?
当然, Gradle的参数配置可以帮我们实现这些.
主要
(1) 常用库的展示与配置.
(2) 统一管理项目和库的版本.
(3) 设置项目的私有参数.
1. 常用库
编程三剑客, RxJava+Retrofit+Dagger.
常用: ButterKnife依赖注解, Glide/Picasso图片处理.
使用根项目(rootProject)的参数管理子项目的版本.
apply plugin: 'me.tatarka.retrolambda' // Lambda表达式apply plugin: 'com.android.application' // Android应用apply plugin: 'com.neenbedankt.android-apt' // 编译时类apply plugin: 'com.android.databinding' // 数据绑定def cfg = rootProject.ext.configuration // 配置def libs = rootProject.ext.libraries // 库android { compileSdkVersion cfg.compileVersion buildToolsVersion cfg.buildToolsVersion defaultConfig { applicationId cfg.package minSdkVersion cfg.minSdk targetSdkVersion cfg.targetSdk versionCode cfg.version_code versionName cfg.version_name buildConfigField "String", "MARVEL_PUBLIC_KEY", "\"${marvel_public_key}\"" buildConfigField "String", "MARVEL_PRIVATE_KEY", "\"${marvel_private_key}\"" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } // 注释冲突 packagingOptions { exclude 'META-INF/services/javax.annotation.processing.Processor' }}dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' // Android compile "com.android.support:design:${libs.supportVersion}" compile "com.android.support:appcompat-v7:${libs.supportVersion}" compile "com.android.support:cardview-v7:${libs.supportVersion}" compile "com.android.support:recyclerview-v7:${libs.supportVersion}" compile "com.android.support:palette-v7:${libs.supportVersion}" // Retrofit compile "com.squareup.retrofit:retrofit:${libs.retrofit}" compile "com.squareup.retrofit:converter-gson:${libs.retrofit}" compile "com.squareup.retrofit:adapter-rxjava:${libs.retrofit}" // ReactiveX compile "io.reactivex:rxjava:${libs.rxandroid}" compile "io.reactivex:rxandroid:${libs.rxandroid}" // Dagger compile "com.google.dagger:dagger:${libs.dagger}" apt "com.google.dagger:dagger-compiler:${libs.dagger}" compile "org.glassfish:javax.annotation:${libs.javax_annotation}" // Others compile "com.jakewharton:butterknife:${libs.butterknife}" // 资源注入 compile "com.github.bumptech.glide:glide:${libs.glide}" // 图片处理 compile "jp.wasabeef:recyclerview-animators:${libs.recycler_animators}" // Recycler动画 compile "de.hdodenhof:circleimageview:${libs.circleimageview}" // 头像视图}

项目版本:
def cfg = rootProject.ext.configuration
cfg.compileVersion
库版本:
def libs = rootProject.ext.libraries
${libs.retrofit}
2. 参数管理
buildConfigField管理私有参数, 配置在gradle.properties里面.
android { defaultConfig { buildConfigField , , ${marvel_public_key}\ buildConfigField , , ${marvel_private_key}\ }}
设置参数的类型\变量名\位置三个部分.
marvel_public_key = 74129ef99c9fd5f7692608f17abb88f9marvel_private_key = 281eb4f077e191f7863a11620fa1865f2940ebeb
未指定路径, 默认是配置在gradle.properties中.
两个地方可以配置参数, 一个是项目的build.gradle, 一个是gradle.properties.
项目中使用BuildConfig.xxx引入参数.
MarvelSigningIterceptor signingIterceptor = new MarvelSigningIterceptor( BuildConfig.MARVEL_PUBLIC_KEY, BuildConfig.MARVEL_PRIVATE_KEY)
3. 版本管理
版本管理配置在项目的build.gradle中, 包含两个部分, 一个是项目的版本, 一个是库的版本. 把常用参数设置成为变量. 子项目使用rootProject.ext.xxx的形式引入.
ext { configuration = [ package : "me.chunyu.spike.springrainnews", buildToolsVersion: "23.0.1", compileVersion : 23, minSdk : 14, targetSdk : 23, version_code : 1, version_name : "0.0.1", ] libraries = [ supportVersion : "23.1.1", retrofit : "2.0.0-beta2", rxandroid : "1.1.0", dagger : "2.0", javax_annotation : "10.0-b28", butterknife : "7.0.1", glide : "3.6.1", recycler_animators: "2.1.0", circleimageview : "2.0.0" ]}buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.0.0-alpha5' classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8' classpath 'me.tatarka:gradle-retrolambda:3.2.4' classpath 'com.android.databinding:dataBinder:1.0-rc4' }}allprojects { repositories { jcenter() }}task clean(type: Delete) { delete rootProject.buildDir}

通过这样的方式管理Android项目, 可以便捷的更改版本号, 所有模块统一.
OK, that’s all! Enjoy it!
