Proguard/R8 exception to a keep rule-CodePudding

I am trying to remove logging using R8/Proguard, and I used

-assumenosideeffects class android.util.Log {
    v(...);
    d(...);
    i(...);
    w(...);
    e(...);
}

which works fine. The issue arrised when trying to remove the custom logging in com.mypackage:

-assumenosideeffects class com.mypackage.MyCustomLogger {
    v(...);
    d(...);
    i(...);
    w(...);
    e(...);
}

I have a rule that keeps all the public methods of the public classes from com.mypackage:

-keep, allowoptimization public class com.mypackage.** {
    public *;
}

which I can't remove due to the scope of the project. This rule seemingly overrides the assumenosideeffects rule, and here is my question: how do I specify an exception to this keep rule? I know about the -if option but I haven't seen it anywhere used in the negative. I've tried writing -if class !com.mypackage.Logger before the -keep rule, but the build is taking a ridiculous amount of time and just never finishes.

CodePudding user response：

I've found the answer, I need to add my Logger class within the keep rule like so:

-keep, allowoptimization public class !com.mypackage.MyCustomLogger, com.mypackage.** {
    public *;
}
