Unresolved class name proguard-rules Android Studio 4.0

When I update to Android Studio 4.0 proguard-rules it shows warning Unresolved class name. Below is example but I sure it still waring the exist class in my project.

-keep class com.squareup.haha.** { *; }
-keep class com.squareup.leakcanary.** { *; }

If I change from ** to * this warning is gone.

-keep class com.squareup.haha.* { *; }
-keep class com.squareup.leakcanary.* { *; }

Does anyone get this? Should I ignore this warning or it's bug of Android Studio 4.0?

`If you right-click on error, there is option "suppress for statement", after that AS adds a comment such as:

noinspection ShrinkerUnresolvedReference

-keep class not.existing

And with this comment there is no error for "not.existing".`

Replace .** with ** as workaround. No compile error and classes are kept.

-keep class com.squareup.haha** { *; }
-keep class com.squareup.leakcanary** { *; }

A folder and its subfile. I have tested this:

com.xx.xx.* { *; }

I guess that it may contain multiply folders and subfile. I've not tested this:

com.xx.xx.**.* {*;}

All of these answers are mere non-sense because:

LeakCanary is being added as debugImplementation.

  • it makes no sense to have rules for classes which do not exist in release builds.
  • it makes even less sense to obfuscate debug builds.

In case you may require any of these rules, you've added it to the wrong build-type.

replace

.**

with 

.*.*

result 

-keep class com.squareup.haha.*.* { *; }
-keep class com.squareup.leakcanary.*.* { *; }
