将Unity从2021.3.31升级到2022.3.59之后，使用Unity的出包接口，运行到GradleBuild会出现两种报错：

1、

Execution failed for task ':unityLibrary:packageReleaseResources'.
> Error while evaluating property 'namespace' of task ':unityLibrary:packageReleaseResources'
   > Failed to calculate the value of task ':unityLibrary:packageReleaseResources' property 'namespace'.
      > Failed to calculate the value of property 'namespace'.
         > Package Name not found in xxx\Library\Bee\Android\Prj\IL2CPP\Gradle\unityLibrary\src\main\AndroidManifest.xml, and namespace not specified. Please specify a namespace for the generated R and BuildConfig classes via android.namespace in the module's build.gradle file like so:
           
           android {
               namespace 'com.example.namespace'
           }，
2、

Execution failed for task ':launcher:mergeDexRelease'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.DexMergingTaskDelegate
   > There was a failure while executing work items
      > A failure occurred while executing com.android.build.gradle.internal.tasks.DexMergingWorkAction
         > com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

           Type {packagename}.android.BuildConfig is defined multiple times: xxx\Library\Bee\Android\Prj\Mono2x\Gradle\launcher\build\intermediates\project_dex_archive\release\out\billion\cash\free\games\jackpot\casino\slots\android\BuildConfig.dex, xxx\Library\Bee\Android\Prj\Mono2x\Gradle\launcher\build\intermediates\sub_project_dex_archive\release\out\6b9d648f1114bbf97287d57921a7f24786f19cc3d9553f24c70f33c3cdc70167_7.jar:classes.dex

这两个报错的原因是同一个问题，错误2的提示： **BuildConfig 类被多次定义**，是因为多个模块（如 :launcher 和 :unityLibrary）使用了相同的 namespace，导致生成的 BuildConfig 类重复，

结合报错得出结论：gradle工程中多个模块中应该有相同的 namespace ，导致生成的BuildConfig 类重复，再根据错误一的提示，去修改指定模块的namespace 即可。
