Proguard

Question

我刚刚将我项目中 Java 的版本从 8 切换到 11，现在我遇到了 Proguard 6.2.2 和 sbt-proguard 0.3.0 的问题，选项如下：

-dontnote,
-dontwarn,
-dontoptimize,
-dontusemixedcaseclassnames,
-keep public class org.slf4j.** { *; },
-keep public class ch.** { *; },
-keep class org.bouncycastle.** { *; },
-keepnames public class * {
  public static ** classTag();
  },
-keepclasseswithmembers public class * {
   public static void main(java.lang.String[]);
  },
-keepclassmembers class * {
  ** MODULE$;
  },
-keepclasseswithmembernames,includedescriptorclasses class * {
  native <methods>;
  },
-keepclassmembers,allowoptimization enum * {
  public static **[] values();
  public static ** valueOf(java.lang.String);
  },
-keepattributes SourceFile,LineNumberTable

这是堆栈跟踪：

Unexpected error while performing partial evaluation:
   Class       = [akka/actor/ActorSelection$$anonfun]
   Method      = [applyOrElse(Ljava/lang/String;Lscala/Function1;)Ljava/lang/Object;]
   Exception   = [java.lang.IllegalArgumentException] (Can't find common super class of [akka/actor/SelectChildPattern] (with 1 known super classes) and [akka/actor/SelectChildName] (with 1 known super classes))

我尝试添加这些选项但没有成功：

-keep class akka.actor.** { *; },
-keep interface akka.actor.** { *; },
-keep enum akka.actor.** { *; },
-keep class akka.actor.SelectChildPattern { *; },
-keep class akka.actor.ActorSelection { *; },
-keep class akka.actor.SelectChildName { *; }

我可以看到 Akka 在库 jar 中：

[debug] -libraryjars "/Users/izhavoronkov/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/com/typesafe/akka/akka-actor_2.12/2.5.26/akka-actor_2.12-2.5.26.jar"

此外，如果我设置 -dontpreverify，我可以在 jar 中找到丢失的 Akka 类，并且它们不会像预期的那样被混淆。不知道混淆器或配置有什么问题。

我在 Java 8.

中没有这些问题

问题通过添加-libraryjars $java_home_11/jmods/java.base.jmod参数解决
