Android Gradle 2.3.3 升級 3.0.1 小記錄
- 2019 年 12 月 30 日
- 筆記
和尚因為種種原因需要升級 Android Gradle，Gradle > 3.0 時默認支援 Java 8；每次大版本升級都會涉及很多內容，和尚儘可能慎重，但還是簡單記錄一下升級過程中遇到的問題；
升級 classpath 'com.android.tools.build:gradle:3.0.1'
和尚從 2.3.3 升級到 3.0.1 同步之後會有很多問題；
Q1:
Unable to resolve dependency for ':testsdk@debug/compileClasspath': Could not resolve project :testlibrary. Unable to resolve dependency for ':testsdk@debugAndroidTest/compileClasspath': Could not resolve project :testlibrary. ...
A1:
Gradle 3.0.0 以後不能用 debugCompile project / debugCompile project 方式替換為 implementation project 即可；
debugCompile project(path: ':testlibrary', configuration: 'debug') releaseCompile project(path: ':testlibrary', configuration: 'release') 替換為 implementation project(':testlibrary')
Q2:
All flavors must now belong to a named flavor dimension. Learn more at https://d.android.com/r/tools/flavorDimensions-missing-error-message.html
A3:
所有類型都必須屬於一個指定的類型維度，即一個產品特性組。必須將所有類型分配給類型維度；在需要修改的 Module.build 添加 flavorDimensions "versionCode" 即可；
defaultConfig { minSdkVersion rootProject.ext.minSdkVersion targetSdkVersion rootProject.ext.targetSdkVersion versionCode 1 versionName "1.0" flavorDimensions "versionCode" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" }
目前同步完之後沒有異常，但是 debug 運行又會有新的問題；
Q3:
Annotation processors must be explicitly declared now. The following dependencies on the compile classpath are found to contain annotation processor. Please add them to the annotationProcessor configuration. - butterknife-7.0.1.jar (com.jakewharton:butterknife:7.0.1) Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior. Note that this option is deprecated and will be removed in the future. See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.
A3:
和尚在項目中應用到 ButterKnife，需要添加註解處理器，使用 annotationProcessor 配置依賴項；
compile "com.jakewharton:butterknife:7.0.1" 替換為 implementation "com.jakewharton:butterknife:7.0.1" annotationProcessor "com.jakewharton:butterknife:7.0.1"
Q4:
Execution failed for task ':test:javaPreCompileDebug'. > Annotation processors must be explicitly declared now. The following dependencies on the compile classpath are found to contain annotation processor. Please add them to the annotationProcessor configuration. - compiler-1.1.0.jar (android.arch.lifecycle:compiler:1.1.0) Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior. Note that this option is deprecated and will be removed in the future. See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.
A4:
和尚在項目中使用了 Lifecycle，需要添加 Lifecycle 依賴項，刪除以前 compile lifecycle 方式，將 Google Maven 程式碼庫添加到項目中即可；和尚未使用 AndroidX 可以按需要自定義添加；
def lifecycle_version = "1.1.1" // 包含ViewModel和LiveData implementation "android.arch.lifecycle:extensions:$lifecycle_version" // 僅僅包含ViewModel implementation "android.arch.lifecycle:viewmodel:$lifecycle_version" // 僅僅包含LiveData implementation "android.arch.lifecycle:livedata:$lifecycle_version" // 僅僅包含Lifecycles implementation "android.arch.lifecycle:runtime:$lifecycle_version" annotationProcessor "android.arch.lifecycle:compiler:$lifecycle_version" // For Kotlin use kapt instead of annotationProcessor // 如果用Java8, 用於替代compiler implementation "android.arch.lifecycle:common-java8:$lifecycle_version" // 可選，ReactiveStreams對LiveData的支援 implementation "android.arch.lifecycle:reactivestreams:$lifecycle_version" // 可選，LiveData的測試 testImplementation "android.arch.core:core-testing:$lifecycle_version"
Q5:
和尚目前運行打包都正常，但是同樣的程式碼在其他開發同事上運行異常；
Type def recipe not found: /Users/gitspace/SogouNovel/commonlib/build/intermediates/typedefs.txt
A5:
和尚嘗試之後發現，升級到 Gradle 3.0 之後，lamba 的版本也需要更新，將 lamba 的版本更新到 3.7.0 即可；
dependencies { classpath 'com.android.tools.build:gradle:3.0.1' classpath 'com.sogou.compress:compress-plugin:1.0.1' classpath 'me.tatarka:gradle-retrolambda:3.7.0' //retrolambda }
Tips:
和尚建議在升級過程中注意混淆文件的處理，尤其是藉助三方 SDK 時，注意官網混淆文件的添加；
至此，和尚在升級過程中遇到的小問題基本解決，大部分都可以在官網或參考各路大神的部落格，但和尚還是記錄嘗試一下，對以後遇到的問題進行擴展整理；如有問題，請多多指導！
