Java 错误：执行'；：应用程序：packageRelease'&燃气轮机；无法计算..\app\build\intermediates\classes proguard\..\release\classes.jar的哈希

我正试图用minifyEnabled true编译我的apk

 buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.config
    }
}

我知道我需要在“proguard rules.pro”文件中写入“dontwarn”，但我不知道确切要写入什么
这里是警告的一小部分：

如果你真的迫切需要建造它。。。在build.gradle文件中禁用minifyEnabled（minifyEnabled false）。之后重新启用它

对于毕加索，您可以尝试：

-dontwarn com.squareup.picasso.**

etc

我也面临着这个问题，不知何故它删除了一些构造函数。
