buildSrc

在项目根目录下新建一个名为buildSrc的文件夹(与项目里的app文件夹同级)。

在buildSrc文件夹里创建名为build.gradle.kts的文件

plugins { `kotlin-dsl` } repositories { jcenter() } 在buildSrc文件夹里创建src/main/kotlin文件夹，在src/main/kotlin目录下新建一个包，并在该包下创建kt文件(Dep.kt)。如下图所示

Deps.kt 字符串需要使用双引号""

/** * Created by Donkey * on 2:25 PM */ package donkey.dependencies object Versions { const val compileSdk = 29 const val buildTools = "29.0.3" const val minSdk = 21 const val targetSdk = 29 const val versionCode = 1 const val versionName = "1.0" const val kotlin = "1.3.72" const val core_ktx = "1.3.0" const val appcompat = "1.1.0" const val constraintLayout = "1.1.3" const val junit = "4.12" const val test_junit = "1.1.1" const val test_espresso = "3.2.0" } object Deps { const val kotlin_stdlib = "org.jetbrains.kotlin:kotlin-stdlib-jdk7:${Versions.kotlin}" const val core_ktx = "androidx.core:core-ktx:${Versions.core_ktx}" const val appcompat = "androidx.appcompat:appcompat:${Versions.appcompat}" const val constraintLayout = "androidx.constraintlayout:constraintlayout:${Versions.constraintLayout}" const val junit = "junit:junit:${Versions.junit}" const val test_junit = "androidx.test.ext:junit:${Versions.test_junit}" const val test_espresso ="androidx.test.espresso:espresso-core:${Versions.test_espresso}" }

build.gradle（module） 使用

import donkey.dependencies.Versions import donkey.dependencies.Deps apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions' android { compileSdkVersion Versions.compileSdk buildToolsVersion Versions.buildTools defaultConfig { applicationId "com.wanandroid" minSdkVersion Versions.minSdk targetSdkVersion Versions.targetSdk versionCode Versions.versionCode versionName Versions.versionName testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } } } dependencies { implementation fileTree(dir: "libs", include: ["*.jar"]) implementation Deps.kotlin_stdlib implementation Deps.core_ktx implementation Deps.appcompat implementation Deps.constraintLayout testImplementation Deps.junit androidTestImplementation Deps.test_junit androidTestImplementation Deps.test_espresso }

build.gradle(project)

// Top-level build file where you can add configuration options common to all sub-projects/modules. import donkey.dependencies.Versions buildscript { repositories { google() jcenter() } dependencies { classpath "com.android.tools.build:gradle:4.0.0" classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$Versions.kotlin" // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { google() jcenter() } } task clean(type: Delete) { delete rootProject.buildDir }
