我有一个由以下模块组成的应用程序：

/app
/common
/customviews
/model

现在我想混淆我的代码用于生产,所以我在所有模块的所有build.gradle文件上添加以下行.

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
    }
}

该文件包含以下规则：

-dontnote android.net.http.*
-dontnote org.apache.commons.codec.**
-dontnote org.apache.http.**


-dontwarn okhttp3.**
-dontwarn okio.**
-dontwarn javax.annotation.**
-dontwarn org.conscrypt.**
-dontwarn retrofit2.Platform$Java8


-keepnames class okhttp3.internal.publicsuffix.PublicSuffixDatabase

-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**

该应用程序编译正常,但运行时我得到以下异常：

b.g.b.a.ac: Incorrect resolution sequence for Java constructor public constructor a() defined in com.myexample.myapp.model.a.e.a[b@eb11a88] (b.g.b.a.a.d.a.f.a.j: class com.myexample.myapp.model.a.e.a)

我顺便使用Kotlin.
