2020-08-12 Showing All Issues Multiple commands produce ' phase “[CP] Copy Pods Resources”

子Pod 用到xxx.xcassets
主工程也用到Images.xcassets

就一直报错！！！
pod 版本 1.8.4
Xcode版本 11.x

Multiple commands produce '/Users/xxx/Library/Developer/Xcode/DerivedData/xxx-dtmfbratpdgyklbqvnmbtbnwhaje/Build/Products/Debug-iphoneos/xxx.app/Assets.car':

1. Target 'xxx' (project 'xxx') has compile command with input '/Users/huchu/Desktop/xxx/xxx/xxx/Images.xcassets'
2. That command depends on command in Target 'xxx' (project 'xxx'): script phase “[CP] Copy Pods Resources”

1、
搜索podspec文档，需要子pod不能用这种方式，需要包装到bundle包里面

  s.resources = "xxx/Resources/*.{xcassets,plist,json,png}"

即上面改为

spec.resource_bundles = {
    'MapBox' => ['MapView/Map/Resources/*.png'],
    'MapBoxOtherResources' => ['MapView/Map/OtherResources/*.png']
  }

这不是闹着玩吗， 这用的时候代码不就很麻烦了，还得指定bundle，

2、
还有一种方法，就是手动删除!

3、
还有一种方法，说是修改workspace settings

这显然不合适，既然有new build system 为啥要用legacy！

4、
还有一种做法就是 修改project.pbxproj, 将这个objectVersion版本号强制改为 小于50

{
    archiveVersion = 1;
    classes = {
    };
    objectVersion = 51;
    objects = {

        # @return [String] Returns Minimum Xcode Object version for FileLists
        #
        MIN_FILE_LIST_OBJECT_VERSION = 50


       class << self
          # @param  [Xcodeproj::Project::Object::AbstractObject] object
          #
          # @return [Boolean] Whether input & output paths for the given object
          #         should be stored in a file list file.
          #
          def input_output_paths_use_filelist?(object)
            unless object.project.root_object.compatibility_version.nil?
              version_match = object.project.root_object.compatibility_version.match(/Xcode ([0-9]*\.[0-9]*)/).to_a
            end
            if version_match&.at(1).nil?
              object.project.object_version.to_i >= MIN_FILE_LIST_OBJECT_VERSION
            else
              Pod::Version.new(version_match[1]) >= Pod::Version.new(MIN_FILE_LIST_COMPATIBILITY_VERSION)
            end
          end

但这种方式后面替换脚本Pods-xxx-resources.sh 控制图片是否需要每次编译都打包不支持

最后

从https://github.com/CocoaPods/CocoaPods/issues/8122

找到启发：

在Podfile下面添加这么一行配置，

 platform :ios, '9.0'
install! 'cocoapods', :disable_input_output_paths => true

终于算可以了， 只要肯下功，铁棒磨成针，即使很无聊，它也是个问题的存在！
这个succesed 不容易啊
