minifyEnabled为true时，Android Studio Build卡住了

Question

Android Studio生成签名Apk陷入困境

app:transformClassesAndResourcesWithProguardRelease
ExcecuteTransform

当minifyEnabled为false时，它可以工作

我的app.gradle文件

apply plugin: 'com.android.application'


android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.ashishclasses"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 3
        versionName "1.0.2"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources false
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.google.firebase:firebase-auth:16.1.0'

}

apply plugin: 'com.google.gms.google-services'

我甚至删除了所有的proguard规则，现在proguard-rules.pro只是空文件

请告诉我如何在启用proguard时构建apk

Answer 1

我一直在运行我的构建，最后20分钟后

Gradle build finished in 20 m 45 s 428 ms

所以我的问题解决了但实际上并没有解决。

我签署的apk的简单构建需要1-2分钟，并且启用缩小20分钟

我的硬件也不差，

我有6GB的ram和ssd，并使用arch linux和AMD A8处理器
