Kotlin Gradle DSL统一构建脚本

使用Kotlin编写settings.gradle.kts

将工程根目录的settings.gradle改为settings.gradle.kts并修改相应的属性

include(":module_weather")
include(":module_voice_setting")
include(":module_setting")
include(":module_joke")
include(":module_developer")
include(":module_constellation")
include(":module_app_manager")
include(":module_map")
include(":lib_voice")
include(":lib_network")
include(":lib_base")
include(":app")
rootProject.name = "AiVoiceApp"
rootProject.buildFileName="build.gradle.kts"

使用Kotlin编写project-build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    val kotlin_version = "1.3.71"
    val gradle_version = "4.0.1"
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:${KotlinConstants.gradle_version}")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:${KotlinConstants.kotlin_version}")
    }
}
allprojects {
    repositories {
        google()
        jcenter()
    }
}

tasks {
    val clean by registering(Delete::class) {
        delete(buildDir)
    }
}

使用Kotlin编写app-build.gradle

//引用插件
plugins {
    id("com.android.application")
    kotlin("android")
    kotlin("android.extensions")
    kotlin("kapt")
}

//Android属性
android {
    compileSdkVersion(AppConfig.compileSdkVersion)
    buildToolsVersion(AppConfig.buildToolsVersion)
    defaultConfig {
        applicationId = AppConfig.applicationId
        minSdkVersion(AppConfig.minSdkVersion)
        targetSdkVersion(AppConfig.targetSdkVersion)
        versionCode = AppConfig.versionCode
        versionName = AppConfig.versionName
    }
    //ARouter
    kapt {
        arguments {
            arg("AROUTER_MODULE_NAME", project.name)
        }
    }

    //签名类型
    signingConfigs {
        register("release") {
            //别名
            keyAlias = "key0"
            //别名密码
            keyPassword = "123456"
            //路径
            storeFile = file("/src/main/jks/aivoice.jks")
            //密码
            storePassword = "123456"
        }
    }
    
    //编译类型
    buildTypes {
        getByName("release") {
            isMinifyEnabled = false
            //自动签名打包
            signingConfig = signingConfigs.getByName("release")
            proguardFiles(
                getDefaultProguardFile("proguard-android-optimize.txt"),
                "proguard-rules.pro"
            )
        }

    }

    //输出类型
    android.applicationVariants.all {
        //编译类型
        val buildType = this.buildType.name
        outputs.all {
            //输出APK
            if (this is com.android.build.gradle.internal.api.ApkVariantOutputImpl) {
                if (buildType == "release") {
                    this.outputFileName = "AI_V${defaultConfig.versionName}_$buildType.apk"
                }
            }
        }
    }

    //依赖操作
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
}

dependencies {
    implementation(fileTree(mapOf("dir" to "libs", "include" to listOf("*.jar"))))
    implementation(project(":lib_base"))
    if (!ModuleConfig.isApp) {
        implementation(project(":module_app_manager"))
        implementation(project(":module_constellation"))
        implementation(project(":module_developer"))
        implementation(project(":module_joke"))
        implementation(project(":module_map"))
        implementation(project(":module_setting"))
        implementation(project(":module_voice_setting"))
        implementation(project(":module_weather"))
    }
    //运行时注解
    kapt(DependenciesConfig.AROUTER_COMPILER)
}

kotlin-gradle-dsl构建脚本
