How to configure ProGuard settings for ButterKnife 8?

Question

I am running ButterKnife 8.5.1 in my Android application. If I try to make ProGuard settings for ButterKnife, I still have crashes in my version. There is a problem on the official ButterKnife Github page that says you are making the following settings:

-keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class **$$ViewBinder { *; }

-keepclasseswithmembernames class * {
     @butterknife.* <fields>;
}

-keepclasseswithmembernames class * {
    @butterknife.* <methods>;
}

Alternatively, it is written to use the following settings:

# Butterknife
-dontwarn butterknife.internal.**
-keep class **$$ViewInjector { *; }
-keepnames class * { @butterknife.InjectView *;}

None of them work with my configuration. I still had crashes when accessing Views related to ButterKnife. So, are there any new settings you need to make for ButterKnife 8?
