如何阻止 R8 混淆 lambdas？

如何解决如何阻止 R8 混淆 lambdas？

我正在使用 R8 对我的应用程序进行 Android 混淆。由于我使用了许多第三方库，因此我制定了一个保留规则，以确保 R8 仅混淆我应用中的代码，而不混淆第三方代码。

-keep class !com.mycompany.myapp.**,** { *; }

这在大多数情况下都有效，并且可以阻止类在第三方库中（即不在 com.mycompany.myapp 包或子包中）被混淆。

但是，我看到许多 lambda 类仍然被混淆，还有 -CC 类似乎也与 lambda 相关。以下是我的映射文件中的一些示例：

如何更改我的保留规则以确保此类类不会被混淆？
