Proguard警告已删除的类

Question

我在Android Studio中使用proguard来混淆我的代码。我已经从我的项目中删除了许多类，并且没有使用它们，但是proguard警告我这些删除的类。如果我不使用proguard，应用程序可以正常编译。

我尝试了Invalidate Caches/Restart选项，但没有效果。

以下是警告:

build.gradle中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 { 
*;
}

对于任何有相同问题的人，只需删除整个build文件夹即可解决问题。
