android-studio - Android Studio Gradle版本Build耗时无限

Question

我最近将代码库更新为Androidx，现在尝试使用以下命令构建生产版本

> ./gradlew assembleProduction

它继续在流程上构建transformClassesAndResourcesWithProguardForProductionRelease

这是输出

我的gradle.properties看起来像这样

> org.gradle.jvmargs=-Xmx3096m -XX:MaxPermSize=512m
> -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

我正在使用proguard并发布buildType有以下内容

minifyEnabled true
useProguard true
shrinkResources true
zipAlignEnabled true
debuggable false

我尝试使用和不使用androidx proguard但结果相同

-keep class androidx.appcompat.widget.** { *; }
-dontwarn com.google.android.material.**
-keep class com.google.android.material.** { *; }

-dontwarn androidx.**
-keep class androidx.** { *; }
-keep interface androidx.** { *; }

您能帮我解决这个问题吗，我可以生成一个签名的apk

您正在使用哪个版本的Android Studio？ 3.4？

当您使用R8而不是Proguard进行编译时会发生什么？有时错误消息会更明确。
