android - 错误:在根项目中找不到任务 'proguardRelease'

Question

有任何想法吗？刚刚更新了Android Studio和相关的构建工具，它的gradle / proGuard破了。有了我之前的配置，并使用 minifyEnabled true ，它拒绝播放:

Cannot resolve symbol 'getDefaultProguardFile'

如果我注释掉minifyEnabled和proguardFiles条目，则会得到:

Error:FAILURE: Build failed with an exception.

* What went wrong:
Task 'proguardRelease' not found in root project 'testApp'.

应用程序build.gradle的位置是:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 16
    buildToolsVersion '21.1.2'
    defaultConfig {
        applicationId 'foo.bar.testApp'
        minSdkVersion 16
        targetSdkVersion 16
        versionCode 7
        versionName '0.5.0 - Alpha test'
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_6
        targetCompatibility JavaVersion.VERSION_1_6
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    compile 'com.android.support:support-v4:21.0.3'
    compile project(':androidsvg')
    compile 'com.google.code.gson:gson:2.3.1'
    compile 'com.opencsv:opencsv:3.1'
    compile 'com.jjoe64:graphview:4.0.0'
}

项目的build.gradle文件为:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

并形成日志，报错:

该文件在那里并且可以访问例如

ls /usr/local/opt/Android_sdk/tools/proguard/
README              examples            proguard-android.txt
ant             lib             proguard-project.txt
bin             license.html
docs                proguard-android-optimize.txt

Answer 1

它应该是:

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

您得到的是 proguardFile而不是 proguardFiles，因此只需在末尾添加-s即可。
