无法删除"-忽略警告“；来自R8配置（Android Proguard问题）

我正在尝试构建一个启用proguard和r8的android应用程序。我添加了“-printconfigurationfull-r8-config.txt”来打印完整的r8配置

问题：即使在之后。由于build.gradle中没有依赖项，我在文件full-r8-config.txt的末尾得到以下条目

App->build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.3"

    defaultConfig {
        applicationId "com.proguard.kotlintest2"
        minSdkVersion 19
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

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

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

buildscript {
    ext.kotlin_version = "1.3.72"
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.0.0"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

现在，当使用R8时，Android Gradle插件强制使用

-ignorewarnings

选项，并且没有办法禁用它

这样做的基本原理是，许多现有的配置文件都广泛使用了

-dontwarn

，在警告方面没有与Proguard兼容的好方法
