Xcode编译问题----“Multiple commands

弱鸡拉完项目Build遇到的ERROR, 如下所示:

Multiple commands produce '/Users/Tomato/Library/Developer
/Xcode/DerivedData/XXXX-fjwfdlboiwngkmbkqoefqmnbrale/
Build/Products/Debug-iphoneos/XXXX.app/Frameworks/App.framework':
1) Target 'XXXX' has copy command 
from 
'/Users/Tomato/Desktop/SpringCoca/XXXX/Pods/FlutterXXSDK/Classes/App.framework' 
to 
'/Users/Tomato/Library/Developer/Xcode/DerivedData/XXXX-fjwfdlboiwngkmbkqoefqmnbrale/Build/Products/Debug-iphoneos/XXXX.app/Frameworks/App.framework'
2) That command depends on command in Target 'XXXX': 
script phase “[CP] Embed Pods Frameworks”

“Multiple commands produce ...”的产生原因:

Workspace Setting 的 "New Build System"会对构建中的元素循环进行严格的检查，避免不必要的重建，这个也是错误出现的原因。
