问题描述

你好朋友，
当在新的Android Studio版本中使用proguard规则为3.1.3时，我在app.gradle文件中遇到一个问题.它可以在旧Studio版本2.3.3上正常工作.
我的完整错误Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=debug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.

Hello friends,
I am facing one issue in app.gradle file when use proguard ruls with new android studio version is 3.1.3. its working proper on old studio version 2.3.3.
My full error Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=debug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.

App.Gradle文件:
android { ..................... buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' applicationVariants.all { variant -> variant.outputs.each { output -> output.outputFile = new File(output.outputFile.parent, output.outputFile.name.replace(".apk", "-" + defaultConfig.versionName + ".apk")) } } } } }

App.Gradle file:
android { ..................... buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' applicationVariants.all { variant -> variant.outputs.each { output -> output.outputFile = new File(output.outputFile.parent, output.outputFile.name.replace(".apk", "-" + defaultConfig.versionName + ".apk")) } } } } }

感谢，

推荐答案

适用于Gradle 3.0 + **

For Gradle 3.0+**

android {
...
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        applicationVariants.all { variant ->
            variant.outputs.all {
                def formattedDate = new Date().format('yyyyMMddHHmmss')
                def flavor = variant.name
                def versionName = variant.versionName
                outputFileName = "AppName_${versionName}_${flavor}_${formattedDate}.apk"
            }
        }
    }
}
...
}

结果:

AppName_release_1_20200121175123.apk

AppName_release_1_20200121175123.apk
