我最近将我的代码库更新为 Androidx，现在尝试使用命令构建生产变体
> ./gradlew assembleProduction
它继续在过程 transformClassesAndResourcesWithProguardForProductionRelease 构建
这是输出

You should check your configuration for typos.
Note: there were 6 library classes explicitly being kept.
You don't need to keep library classes; they are already left unchanged.

Note: there were 49 unresolved dynamic references to classes or interfaces.
You should check if you need to specify additional program jars.

Note: there were 1 class casts of dynamically created class instances.
You might consider explicitly keeping the mentioned classes and/or
their implementations (using '-keep').

我的 gradle.properties 看起来像这样

我正在使用 proguard 并发布 buildType 有以下
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.** { *; }
你能帮我解决这个问题，这样我就可以生成一个签名的apk
