Question

我发现混淆会导致字节码中出现奇怪的语法错误，我尝试了多种方法使其正常工作，但是每次都遇到问题。我在IntelliJ中检查了编译后的代码，这就是我可以在此处发布的内容。问题似乎出在Companion对象中，并且它们在混淆过程中可能已损坏。

原始代码：（有效）

companion object {

    lateinit var instance: GTAnticheat
        private set

    val DEBUG = false
}

原始编译代码：（有效）

    public static final GTAnticheat.Companion Companion = new GTAnticheat.Companion((DefaultConstructorMarker)null);

// $FF: synthetic method
   @NotNull
   public static final GTAnticheat access$getInstance$cp() {
      GTAnticheat var10000 = instance;
      if (instance == null) {
         Intrinsics.throwUninitializedPropertyAccessException("instance");
      }

      return var10000;
   }

        @Metadata(

           )

       public static final class Companion {
          @NotNull
          public final GTAnticheat getInstance() {
             return GTAnticheat.access$getInstance$cp();
          }

          private final void setInstance(GTAnticheat var1) {
             GTAnticheat.instance = var1;
          }

          public final boolean getDEBUG() {
             return GTAnticheat.DEBUG;
          }

          private Companion() {

          public Companion(DefaultConstructorMarker $constructor_marker) {
             this();

模糊的编译代码：（确实在工作）

public static final GTAnticheat.a a = new GTAnticheat.a;

// $FF: synthetic method
   @NotNull
   public static final GTAnticheat a() {
      GTAnticheat var10000 = a;
      if (a == null) {
         Intrinsics.throwUninitializedPropertyAccessException("instance");
      }

      return var10000;
   }

   // $FF: synthetic method
   public static final boolean a() {
      return false;
   }

如果我尝试运行混淆的jar，它将引发VerifyError https://hastebin.com/xipixihozi.sql

我对如何编译kotlin不太了解，但是正如您所看到的，有两种名为a（）的方法在Java中是不允许的，而第三个与同伴无关。而且在创建伴侣实例的行上缺少“（）”
