遇到的问题
1.flavorDimensions
错误日志
1
|
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 |
原因:gradle3.0需要使用flavorDimensions做多版本打包,修改如下:
1

|
android { //... defaultConfig { //... flavorDimensions "dimen" } } |
然后在productFlavors中做相应的修改

productFlavors { productA { dimension "dimen" } productB { dimension "dimen" } } |
配置多个flavorDimensions

2.apk命名
错误日志

Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=busDebug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl. Open File |

applicationVariants.all { variant -> variant.outputs.each { output -> def outputFile = output.outputFile if (outputFile != null && outputFile.name.endsWith( '.apk' )) { def fileName = "XXX-${defaultConfig.versionCode}-${defaultConfig.versionName}-${releaseTime()}-${productFlavors.name[0]}" if (variant.buildType.name == 'release' ) { fileName += '.apk' } else if (variant.buildType.name == 'debug' ) { fileName += '_debug.apk' } else { fileName += '_other.apk' } output.outputFile = new File(outputFile.parent, fileName) } } } |
gradle3.0 each替换为all,output.outputFile替换为outputFileName,不需要new File了,修改后的代码:

applicationVariants.all { variant -> variant.outputs.all { def fileName = "XXX-${defaultConfig.versionCode}-${defaultConfig.versionName}-${releaseTime()}-${productFlavors.name[0]}" if (variant.buildType.name == 'release' ) { fileName += '.apk' } else if (variant.buildType.name == 'debug' ) { fileName += '_debug.apk' } else { fileName += '_other.apk' } outputFileName = fileName } } |
需要注意的是,使用Build->Generate Signed APK…的时候,生成的apk包会放在一个以渠道名命名的文件夹下
3.Annotation processors must be explicitly declared now.Please add them to the annotationProcessor configuration.

Error:Execution failed for task ':app:javaPreCompilePreProductDebug' . > 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 (butterknife- 7.0 . 1 .jar) 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. |
