Android Proguard警告删除的类

我正在使用proguard在Android Studio中混淆我的代码。 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警告我这些已删除的类。如果我不使用proguard，应用程序的编译效果很好

我尝试了

invalidatecaches/Restart

选项，但没有效果

以下是警告：

以下是

build.gradle

中的

proguard

相关部分：

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

                    'proguard-rules.pro'
        }
