Proguard 警告删除类

Question

我在 Android Studio 中使用混淆器来混淆我的代码。我已经从我的项目中删除了很多类并且没有使用它们，但是混淆器警告我那些被删除的类。如果我不使用混淆器，应用程序编译正常。

我尝试了 Invalidate Caches/Restart 选项，但没有任何区别。

警告如下：

这里是 build.gradle 中的 proguard 相关部分：

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

这是 proguard-rules.pro 文件：

-verbose

-dontwarn android.support.**

-keep class -verbose

-dontwarn android.support.**

-keep class -verbose

-dontwarn android.support.**

-keep class com.mypack.myapp.R { 
*;
}

#below commands for including the line numbers in traces
-renamesourcefileattribute SourceFile    
-keepattributes SourceFile,LineNumberTable.R { 
*;
}

对于遇到相同问题的任何人，只需删除整个 build 文件夹即可解决问题。
