ios - GoogleMaps 作为间接依赖导致构建错误

Question

出于说明目的，两个Xcode项目由Cocoapods创建和依赖管理。第一个是iOS Apps项目，另一个是依赖框架。在没有GoogleMaps的情况下，这两个项目都可以正常构建和运行。如果存在GoogleMaps作为第一个项目的间接依赖项会导致错误，这里是依赖关系树：

AcademiaMainAPP/
├─ TARGETS/AcademiaMainAPP       [Error: Multiple commands produce for Assets.car]
└─ PODS/
   └─ AcademiaMainGUI/
      ├─ TARGETS/AcademiaMainDMO [No error, build & run successfully]
      └─ PODS/
         ├─ GoogleMaps
         └─ AcademiaCoreLIB

将 GoogleMaps 的案例构建为间接依赖项：

默认目标的iOS 应用项目构建错误

错误：

Multiple commands produce '/Users/Academia/Library/Developer/Xcode/DerivedData/AcademiaMainAPP-dchavmxvfznhbifvdocjhrxhitug/Build/Products/Debug-iphonesimulator/Academia.app/Assets.car':
1) Target 'AcademiaMainAPP' (project 'AcademiaMainAPP') has compile command with input '/opt/dev/ios_workspace/academia-main-iosapp/AcademiaMainAPP/Preview Content/Preview Assets.xcassets'
2) That command depends on command in Target 'AcademiaMainAPP' (project 'AcademiaMainAPP'): script phase "[CP] Copy Pods Resources"

警告：

duplicate output file '/Users/Academia/Library/Developer/Xcode/DerivedData/AcademiaMainAPP-dchavmxvfznhbifvdocjhrxhitug/Build/Products/Debug-iphonesimulator/Academia.app/Assets.car'

询问？

现在我们正在使用Xcode 11.4.1。实际上我们没有使用这样的Assets.car。s.static_framework = true在Podspec中为GoogleMaps添加。有关详细信息，请查找我们的Podfile和Podspec作为自爆。事实上，我们需要知道Podfile或Podspec中是否有任何错误或缺少配置。我们对已经解决此类问题的专家的唯一疑问请指导我们解决此问题。
