Tried using this but it did not work.

-keep class com.squareup.okhttp.** { *; }

Answer 1

Actually this seems to be now fixed in OkHttp version 4.11.0, released on April 2023: https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp-bom

I had the same issue and once I updated to this version, the build goes through successfully

Answer 2

Fixed in okhttp 5 https://github.com/square/okhttp/issues/6258

Add rulse from https://raw.githubusercontent.com/square/okhttp/master/okhttp/src/jvmMain/resources/META-INF/proguard/okhttp3.pro

-dontwarn org.conscrypt.**
-dontwarn org.bouncycastle.**
-dontwarn org.openjsse.**
