Gradle 3.0.0的Proguard问题

Question

我正在尝试使用ProGuard和新的Gradle 3.0.0版本创建APK。对于我认为在ProGuard配置文件中忽略的类，我收到了很多警告。相同的配置适用于Gradle 2.3.3但似乎在3.0.0上中断。警告很多，几乎没有读取ProGuard配置。

我的build.gradle

buildscript {
    repositories {
        mavenCentral()
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'com.google.gms:google-services:3.0.0'
        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2'


    }

}


allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://jitpack.io'
        }
        maven {
            url 'https://maven.google.com'
        }

    }
}
android{
 buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                    'proguard-rules.pro'
            signingConfig signingConfigs.release
            lintOptions {
                disable 'MissingTranslation'
            }

        }




compileSdkVersion 27
buildToolsVersion "27.0.1"
defaultConfig {
minSdkVersion 16
targetSdkVersion 27
testInstrumentationRunner 
"android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true

}

Answer 1

我已升级到gradle 3.0.1，大部分警告都已消失。如果您仍然使用3.0.0，请在您的proguard文件中使用它

-dontwarn android.**

不理想，但让它发挥作用。

Answer 2

我有同样的问题，虽然我的案例有点独特，但这是我的解决方案：

升级到新的3.0.1版本（com.android.tools.build:gradle:3.0.1）后，我看到更少的警告（最初我有> 3000警告）。 我的问题的根源是我使用了一个依赖于整个android框架的库（这一个：https://github.com/tony19/logback-android，问题#73）。

我还查看了依赖项（./gradlew app:dependenices），因为我的库依赖于旧的apache http客户端，这也会导致一些警告。我也必须消除它们。

Answer 3

它可能对你有所帮助 Enabling ProGuard for local library modules no longer affects the library's code. Instead, you should run ProGuard on the app module that consumes the library. https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html

Answer 4

在android标记

中添加以下代码

lintOptions {
        // set to true to turn off analysis progress reporting by lint
        quiet true
        // if true, stop the gradle build if errors are found
        abortOnError false
        // if true, only report errors
        ignoreWarnings true
    }
