Android kotlin build.gradle.kts配置

1. 添加 maven 仓库

1. 1. settings配置

1. 1.1. settings.gradle

repositories {    maven {url 'https://maven.aliyun.com/repository/public/'}    mavenCentral()}

1. 1.2. settings.gradle.kts

repositories {    maven {        setUrl("https://maven.aliyun.com/repository/public/")    }    mavenCentral()}

1. 2. gradle配置

1. 2.1. build.gradle

  implementation 'com.github.bumptech.glide:glide:4.12.0'

1. 2.2. build.gradle.kts

    implementation(libs.glide)

  版本号在gradle文件夹下 libs.versions.toml文件中添加

1. 2.2.1. build.gradle.kts

  libs.versions.toml文件用来抽离依赖来加载，文件由 4 个主要部分组成：
  （1）[versions]部分用于声明可以被依赖项引用的版本
  （2）[libraries]部分用于声明坐标的别名
  （3）[bundles]部分用于声明依赖包
  （4）[plugins]部分用于声明插件
  注意：不要使用驼峰命名方式，单词使用 - 分割：

[versions]groovy = "3.0.5"checkstyle = "8.37"[libraries]groovy-core = { module = "org.codehaus.groovy:groovy", version.ref = "groovy" }groovy-json = { module = "org.codehaus.groovy:groovy-json", version.ref = "groovy" }groovy-nio = { module = "org.codehaus.groovy:groovy-nio", version.ref = "groovy" }commons-lang3 = { group = "org.apache.commons", name = "commons-lang3", version = { strictly = "[3.8, 4.0[", prefer="3.9" } }[bundles]groovy = ["groovy-core", "groovy-json", "groovy-nio"][plugins]versions = { id = "com.github.ben-manes.versions", version = "0.45.0" }

2. Android Studio 如何配置打包后的文件名称

  我们在新建一个项目然后直接进行Build apk，可以生成一个app_debug.apk的apk文件，那么文件是怎么产生的呢？

2.1. build.gradle

    //**********打包设置开始**********    //自定义生成的apk的地址及名称    def apkName;    signingConfigs {        release {            v1SigningEnabled true            v2SigningEnabled true            storeFile file('./keystore/insour_szyj.keystore')            storePassword 'insour_szyj'            keyAlias 'insour_szyj'            keyPassword 'insour_szyj'        }        debug {            v1SigningEnabled true            v2SigningEnabled true            storeFile file('./keystore/insour_szyj.keystore')            storePassword 'insour_szyj'            keyAlias 'insour_szyj'            keyPassword 'insour_szyj'        }    }    buildTypes {        debug {//            minifyEnabled false//混淆            minifyEnabled true            shrinkResources true            // 不显示Log            buildConfigField "boolean", "LOG_DEBUG", "false"            proguardFiles getDefaultProguardFile('proguard-android.txt'),                    'proguard-rules.pro'            aaptOptions.cruncherEnabled = false            aaptOptions.useNewCruncher = false            apkName = "szyj.apk"            signingConfig signingConfigs.release        }        release {//            minifyEnabled false//混淆            minifyEnabled true            shrinkResources true            // 不显示Log            buildConfigField "boolean", "LOG_DEBUG", "false"            proguardFiles getDefaultProguardFile('proguard-android.txt'),                    'proguard-rules.pro'            aaptOptions.cruncherEnabled = false            aaptOptions.useNewCruncher = false            apkName = "szyj.apk"            signingConfig signingConfigs.release        }    }    android.applicationVariants.all { variant ->        variant.outputs.all {            if (outputFileName.endsWith('.apk')) {                //这里使用之前定义apk文件名称                outputFileName = apkName            }        }    }//    android.applicationVariants.all {//        variant -> variant.outputs.all { output ->//                def date = new Date().format("yyMMdd",//                        TimeZone.getTimeZone("GMT+08"))//                if (variant.buildType.name == 'debug'){//                    output.outputFileName = "项目名称_" +//                            "${android.defaultConfig.versionName}_${date}_debug.apk"//                }else if (variant.buildType.name == 'release'){//                    output.outputFileName = "项目名称_" +//                            "${android.defaultConfig.versionName}_${date}_release.apk"//                }//            }//    }    //**********打包设置结束**********

2.2. build.gradle.kts

  //**********打包设置开始**********    signingConfigs {//        create("release") {//            storeFile = file("./keystore/insour_szyj.keystore")//            storePassword = "insour_szyj"//            keyAlias = "insour_szyj"//            keyPassword = "insour_szyj"//        }        getByName("debug") {            enableV1Signing =true            enableV2Signing =true            enableV3Signing =true            enableV4Signing =true            storeFile = file("./keystore/insour_szyj.keystore")            storePassword = "insour_szyj"            keyAlias = "insour_szyj"            keyPassword = "insour_szyj"        }        register("release") {            enableV1Signing =true            enableV2Signing =true            enableV3Signing =true            enableV4Signing =true            storeFile = file("./keystore/insour_szyj.keystore")            storePassword = "insour_szyj"            keyAlias = "insour_szyj"            keyPassword = "insour_szyj"        }    }    buildTypes {        debug {            isMinifyEnabled = false            isShrinkResources = false            proguardFiles(getDefaultProguardFile(                    "proguard-android-optimize.txt"),                    "proguard-rules.pro")        }        release {            isMinifyEnabled = false            isShrinkResources = false            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        val date = SimpleDateFormat("yyyyMMddHHmmss").format(Date())        outputs.all {            // 判断是否是输出 apk 类型            if (this is com.android.build.gradle                    .internal.api.ApkVariantOutputImpl) {                this.outputFileName = "szyj" +                        "_${android.defaultConfig.versionName}_${date}_${buildType}.apk"            }        }    }    //**********打包设置结束**********

3. sourceSets配置

3.1. build.gradle

    sourceSets {        main {            jniLibs.srcDirs = ['libs']        }    }

3.2. build.gradle.kts

 //jniLibs目录指向libs目录    sourceSets {        getByName("main") {            jniLibs.srcDirs("libs")        }    }

4. BuildConfig不生成

  新建了一个demo，其依赖的AGP版本是8.0.0。但是在运行过程中报了一个错误就是找不到BuildConfig。
重新build了下代码，然后找编译后的代码，发现确实没有生成BuildConfig。清缓存，重启AS都没有用。之前代码相比，也就是AGP的版本升级了下，那猜测是不是跟AGP8.0.0的版本有关，于是在BuildType中手动添加了个buildConfigField，想以此方式强制生成下BuildConfig。

  运行报错

Build Type 'debug' contains custom BuildConfig fields, but the feature is disabled.

  提示BuildConfig 处于禁用状态…看来是新版本的AGP默认禁用了生成BuildConfig。BuildFeatures源码看到了一个配置buildConfig的注释如下。

  果然如此，默认是禁用状态。在buildFeatures配置中把buildConfig值手动设为true，重新build下就好了

    //开启dataBinding    buildFeatures {        dataBinding = true        buildConfig=true    }

5. Kotlin Build.gradle脚本编写（build.gradle.kts）

plugins {    id("com.android.application")    kotlin("android")    kotlin("kapt")}android {    compileSdkVersion(29)    defaultConfig {        applicationId = "com.xxx.xxxxx"        minSdkVersion(21)        targetSdkVersion(29)        versionCode = 27        versionName = "2.2.0"        resConfigs("zh")        ndk {              abiFilters += listOf("armeabi-v7a","arm64-v8a")        }    }    //开启dataBinding    buildFeatures {        dataBinding = true        buildConfig=true    }    //图片已压缩 指定aapt不做图片压缩 因为可能会反而增加图片大小    aaptOptions {//        cruncherEnabled = false    }    //关闭lint检查    lintOptions {        disable("ResourceType")//        abortOnError  = false    }    //jniLibs目录指向libs目录    sourceSets {        getByName("main") {            jniLibs.srcDirs("libs")        }    }    //优化transformClassDexBuilderForDebug的时间    dexOptions {        preDexLibraries = true        maxProcessCount = 8    }    //禁止生成依赖元数据 不上play用不到    dependenciesInfo {        includeInApk = false    }    //jdk1.8支持    compileOptions {        sourceCompatibility = JavaVersion.VERSION_1_8        targetCompatibility = JavaVersion.VERSION_1_8    }    kotlinOptions {        jvmTarget = JavaVersion.VERSION_1_8.toString()    }    //签名配置    signingConfigs {        getByName("debug") {            storeFile = file("../xxx.jks")            storePassword = "xxx"            keyAlias = "xxx"            keyPassword = "xxx"        }    }    buildTypes {        getByName("debug") {            //签名            signingConfig = signingConfigs.getByName("debug")            //git提交次数 作为测试包版本后缀            buildConfigField("int", "GIT_COMMIT_COUNT", getGitCommitCount())        }        register("alpha") {            //继承debug配置            initWith(getByName("debug"))            //混淆            isMinifyEnabled = true            proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")            //ZipAlignEnabled优化            isZipAlignEnabled = true            //移除无用的resource文件            isShrinkResources = true        }        getByName("release") {            //继承alpha配置            initWith(getByName("alpha"))            //关闭debug            debuggable(false)        }    }    //release打包时自定义apk名字、输出路径    android.applicationVariants.all {        outputs.all {            if (this is com.android.build.gradle.internal.api.ApkVariantOutputImpl) {                this.outputFileName = "xxxx.apk"            }        }    }}//获取git提交次数fun getGitCommitCount(): String {    val os = org.apache.commons.io.output.ByteArrayOutputStream()    project.exec {        commandLine = "git rev-list --count HEAD".split(" ")        standardOutput = os    }    return String(os.toByteArray()).trim()}//依赖库apply(from = "depends.gradle")
