Proguard 在 build/outputs/mapping/release 中未生成任何内容

Question

我已将我的应用程序从 ADT 迁移到 Android Studio，因为它已成为官方 IDE。

不过最近发现可以反编译，源码清楚

我在 eclipse 中花了很多时间来混淆我的 apk，所以我还有我的 Proguard 文件，这很好

proguard-project.txt:

我的 build.gradle 是：

buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "com.myapp.mobile"
    minSdkVersion 16
    targetSdkVersion 20
}

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt'
    }
}

    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/dependencies.txt'
    exclude 'META-INF/LGPL2.1'
}

}

compile project(':progressWheel')
compile 'com.google.code.gson:gson:2.2.4'

}

我看到几个 post，他们都说你必须激活它：

minifyEnabled 真但是我的已经激活了...

感谢@Robert Rowntree，我还意识到在运行ning ./gradlew clean assembleRelease

之后 build/outputs/mapping/release 是空的

仍然，我无法让 Proguard 工作？？？没有 proguard 我就无法发布我的应用程序！！！

有什么想法吗？？？

编辑 1：当我运行 gradlew build 时，我得到 BUILD SUCCESSFUL

Answer 1

我删除了 proguard.txt 中的那些行，我的 apk 有更多的混淆。我想要更多，但这是一个好的开始！

-keep public class * {
    public protected *;
}

Proguard 在 build/outputs/mapping/release 中未生成任何内容
