問題一:
Cannot set the value of read-only property ‘outputFile‘ for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=commonDebug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl. Open File
解決方案一:
https://stackoverflow.com/questions/44239235/android-gradle-3-0-0-alpha2-plugin-cannot-set-the-value-of-read-only-property
I used this code
applicationVariants.all { variant -> variant.outputs.each { output -> def outputFile = output.outputFile if (outputFile != null && outputFile.name.endsWith(‘.apk‘)) { //輸出apk名稱為:應用程式名稱.apk def fileName = "xxx.apk" output.outputFile = new File(outputFile.parent, fileName) } } }
**Use all() instead of each()
Use outputFileName instead of output.outputFile if you change only file name (that is your case)**
Example from the guide:
// If you use each() to iterate through the variant objects,// you need to start using all(). That‘s because each() iterates// through only the objects that already exist during configuration time—// but those object don‘t exist at configuration time with the new model.// However, all() adapts to the new model by picking up object as they are// added during execution.android.applicationVariants.all { variant -> variant.outputs.all { outputFileName = "xxx.apk" } }

問題二:
Error:All flavors must now belong to a named flavor dimension. Learn more at https://d.android.com/r/tools/flavorDimensions-missing-error-message.html

大致是說,Plugin 3.0.0之後有一種自動匹配消耗庫的機制,便於debug variant 自動消耗一個庫,然後就是必須要所有的flavor 都屬於同一個維度。
為了避免flavor 不同產生誤差的問題,應該在所有的庫模組都使用同一個foo尺寸。
但是我們從中已經知道解決方案了:
在主 app 的 build.gradle 裡面的
defaultConfig { targetSdkVersion:*** minSdkVersion :*** versionCode:*** versionName :***//版本名後面加句話,意思是flavor dimension 它的維度就是該版本號碼,//這樣維度就是都是統一的了 **flavorDimensions "versionCode"**}

問題三:
Error:Execution failed for task ‘:youyoubao:javaPreCompileCommonDebug‘.> 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-compiler-8.6.0.jar (com.jakewharton:butterknife-compiler:8.6.0) 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.
解決方案三:
在 app 下的 build.gradle 的 defaultConfig 中加一句話:
defaultConfig { ... javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true } }}

Cannot set the value of read-only property ‘outputFile‘ for ApkVariantOutputImpl_Decorated今天升級了AS3.0以後,在項目編譯的時候發現Gradle中報錯了,錯誤如下:Error:(60, 0) Cannot set the value of read-only property ‘outputFile‘ for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=xiaomiRelease, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.<a href="openFile:E:\Studio\MyApplication\CodeBook\build.gradle">Open File</a>經過一番折騰,網上找大牛的解讀,弄明白了output.outputFile變成了唯讀屬性,不能再往裡面寫東西了,以下是3.0之前的配置:
applicationVariants.all { variant -> //批量修改Apk名字 variant.outputs.each { output -> def outputFile = output.outputFile if (outputFile != null && outputFile.name.endsWith(‘.apk‘) && ‘release‘.equals(variant.buildType.name)) { def fileName = outputFile.name.replace("${variant.flavorName}", "V${defaultConfig.versionName}-${variant.flavorName}") fileName = fileName.replace(‘.apk‘, "-${buildTime()}.apk") output.outputFile = new File(outputFile.parent, fileName) } }}
下面是經過修改之後3.0裡面批量修改APK名字的配置:
applicationVariants.all { variant -> //批量修改Apk名字 variant.outputs.all { output -> if (!variant.buildType.isDebuggable()) { //擷取簽名的名字 variant.signingConfig.name //要被替換的源字串 def sourceFile = "-${variant.flavorName}-${variant.buildType.name}" //替換的字串 def replaceFile = "_V${variant.versionName}_${variant.flavorName}_${variant.buildType.name}_${buildTime()}" outputFileName = output.outputFile.name.replace(sourceFile, replaceFile); //遺留問題:如何擷取當前module的name,如CodeBooke這個名字怎麼擷取到 } }}
問題:對於如何在gradle中擷取module的name,還是沒有找到相關的方法,希望有知道的大神留言交流。gradle API:https://developer.android.google.cn/studio/build/gradle-plugin-3-0-0-migration.html#variant_api這是一個對AS 3.0變化總結比較全的部落格:https://mp.weixin.qq.com/s?__biz=MzAwNzc0NjAxMg==&mid=2653391711&idx=1&sn=821eff3f98ab52fc442c6218794b203e&chksm=80aa53ecb7dddafa522d4ebfdf67af2f473365bb0fa2d50ae6df5d00499926ae0d32a5a448d2&mpshare=1&scene=23&srcid=10308c4ICo7GCwuVc683H6eZ#rd
