proguard即使使用keep，也会删除kotlin类构造函数中参数的java名称

Question

我有一个具有以下构造函数的类：

class Configuration @JvmOverloads constructor(val applicationId: String, typesToAutomaticallyLoad: List<AutoLoadableType>,
                                                    val isTestMode: Boolean = false, var userId: String? = null,
                                                    private var videoNetworks: List<MDNetwork> = MDNetwork.values().toMutableList(),
                                                    private var networks: List<MDAdNetwork> = MDNetwork.values().toMutableList(),
                                                    var loadingTimeoutMs: Long = 20000) 

我的proguard文件：

-keep class mypackage.** {
    <init>(...);
    *;
}

禁用minify后，我可以：

   @JvmOverloads
   public Configuration(@NotNull String applicationId, @NotNull List typesToAutomaticallyLoad, boolean isTestMode, @Nullable String userId, @NotNull List videoNetworks, @NotNull List networks) {
      this(applicationId, typesToAutomaticallyLoad, isTestMode, userId, videoNetworks, networks, 0L, 64, (DefaultConstructorMarker)null);
   }

   @JvmOverloads
   public Configuration(@NotNull String applicationId, @NotNull List typesToAutomaticallyLoad, boolean isTestMode, @Nullable String userId, @NotNull List videoNetworks) {
      this(applicationId, typesToAutomaticallyLoad, isTestMode, userId, videoNetworks, (List)null, 0L, 96, (DefaultConstructorMarker)null);
   }

   @JvmOverloads
   public Configuration(@NotNull String applicationId, @NotNull List typesToAutomaticallyLoad, boolean isTestMode, @Nullable String userId) {
      this(applicationId, typesToAutomaticallyLoad, isTestMode, userId, (List)null, (List)null, 0L, 112, (DefaultConstructorMarker)null);
   }

   @JvmOverloads
   public Configuration(@NotNull String applicationId, @NotNull List typesToAutomaticallyLoad, boolean isTestMode) {
      this(applicationId, typesToAutomaticallyLoad, isTestMode, (String)null, (List)null, (List)null, 0L, 120, (DefaultConstructorMarker)null);
   }

   @JvmOverloads
   public Configuration(@NotNull String applicationId, @NotNull List typesToAutomaticallyLoad) {
      this(applicationId, typesToAutomaticallyLoad, false, (String)null, (List)null, (List)null, 0L, 124, (DefaultConstructorMarker)null);
   }

启用minify后，我得到：

   @JvmOverloads
   public Configuration(@NotNull String var1, @NotNull List var2, boolean var3, @Nullable String var4, @NotNull List var5, @NotNull List var6) {
      this(var1, var2, var3, var4, var5, var6, 0L, 64, (DefaultConstructorMarker)null);
   }

   @JvmOverloads
   public Configuration(@NotNull String var1, @NotNull List var2, boolean var3, @Nullable String var4, @NotNull List var5) {
      this(var1, var2, var3, var4, var5, (List)null, 0L, 96, (DefaultConstructorMarker)null);
   }

   @JvmOverloads
   public Configuration(@NotNull String var1, @NotNull List var2, boolean var3, @Nullable String var4) {
      this(var1, var2, var3, var4, (List)null, (List)null, 0L, 112, (DefaultConstructorMarker)null);
   }

   @JvmOverloads
   public Configuration(@NotNull String var1, @NotNull List var2, boolean var3) {
      this(var1, var2, var3, (String)null, (List)null, (List)null, 0L, 120, (DefaultConstructorMarker)null);
   }

   @JvmOverloads
   public Configuration(@NotNull String var1, @NotNull List var2) {
      this(var1, var2, false, (String)null, (List)null, (List)null, 0L, 124, (DefaultConstructorMarker)null);
   }

因此，此proguard配置保留类名、构造函数名，但不保留参数名

如何使其也保留参数名称

Answer 1

您必须添加@SerializedName（“…”）在所有参数下

数据类同步用户( @SerializedName（“用户”） val用户：用户 )
