Proguard R8 警告

Question

使用 r8 时收到这些警告

Missing class org.bouncycastle.jsse.BCSSLParameters (referenced from: void okhttp3.internal.platform.BouncyCastlePlatform.configureTlsExtensions(javax.net.ssl.SSLSocket, java.lang.String, java.util.List) and 1 other context)
Missing class org.bouncycastle.jsse.BCSSLSocket (referenced from: void okhttp3.internal.platform.BouncyCastlePlatform.configureTlsExtensions(javax.net.ssl.SSLSocket, java.lang.String, java.util.List) and 5 other contexts)

Missing class org.openjsse.net.ssl.OpenJSSE (referenced from: void okhttp3.internal.platform.OpenJSSEPlatform.<init>())

尝试使用它，但没有用。

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

Answer 1

使用 R8 编译时缺少类意味着在输入中有对这些类的引用，但它们在输入中没有定义，在程序本身、类路径或库/引导类路径中都没有定义（ android.jar构建 ZE84E323642ADB6DB6 应用程序时） . -keep规则用于保持输入中已经存在的类，并且对缺失的类没有影响（它实际上最终可能会给出更多的缺失类）。

要使有关缺失类的警告静音，可以使用-dontwarn指令，例如：

-dontwarn org.bouncycastle.jsse.BCSSLParameters

在继续添加-dontwarn之前，请确保缺少的类不是由于缺少依赖项造成的，这可能最终导致运行时失败。

固定在 okhttp 5 https://github.com/square/okhttp/issues/6258

添加规则来自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.**
