有什么想法吗？刚刚更新了Android Studio和相关的构建工具以及它的gradle / proGuard。使用我之前的配置， minifyEnabled true ，它拒绝使用：
Cannot resolve symbol 'getDefaultProguardFile'
如果我注释掉minifyEnabled和proguardFiles条目，我会得到一个：
Error:FAILURE: Build failed with an exception.
* What went wrong:
Task 'proguardRelease' not found in root project 'testApp'.
应用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，错误：

该文件存在且可访问，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
答案 0 :(得分：0)
应该是：
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
你有proguardFile而不是proguardFiles，所以只需将-s添加到最后，你应该没问题。
答案 1 :(得分：-1)
您的解决方案应为proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
