【中文标题】在 Kotlin 多平台项目中构建 APK 不起作用：/ 它说 Type xxx.xxx.BuildConfig 被定义了多次

【英文标题】：Build APK in Kotlin Multi-Platform Project is not working :/ It says Type xxx.xxx.BuildConfig is defined multiple times

【问题描述】：

我有一个 kotlin 多平台项目。 当我在模拟器或 android 设备上运行它时，它可以正常工作，但是当我尝试构建 APK 时，它不起作用:)) 它说：

> A failure occurred while executing com.android.build.gradle.internal.tasks.D8MainDexListTask$MainDexListWorkerAction
   > Error while merging dex archives:

     Type xxx.xxx.BuildConfig is defined multiple times:
         /Users/macbook/AndroidStudioProjects/XProject-KMM/shared/build/intermediates/runtime_library_classes_jar/debug/classes.jar:com/xproject/BuildConfig.class, 
         /Users/macbook/AndroidStudioProjects/XProject-KMM/XProject/build/intermediates/transforms/RealmTransformer/xxx/debug/0/com/xxxx/BuildConfig.class

这是我的 Gradle 文件：build.gradle.kts (:Andorid_Project)：

任何帮助将不胜感激。

我会尝试以下方法：

确保您的 shared 和 android 模块具有不同的包名称 尝试进行干净构建/重建
