"Multiple commands produce..." errors in Xcode 12.2, Big Sur

[kacper1703]

For a following Podfile, when trying to build the project multiple errors appear. Excluding some of these frameworks using :binary => false does not help.

Multiple commands produce '/Users/ABCD/Library/Developer/Xcode/DerivedData/MyProject-gfnmwygetouofcguhjlnrmdzrhbp/Build/Products/Debug-iphonesimulator/nanopb/nanopb.framework.dSYM':
1) That command depends on command in Target 'nanopb' (project 'Pods'): script phase “[CP] Copy dSYMs”
2) That command depends on command in Target 'nanopb' (project 'Pods'): script phase “[CP] Copy dSYMs”
3) That command depends on command in Target 'nanopb' (project 'Pods'): script phase “[CP] Copy dSYMs”

Multiple commands produce '/Users/ABCD/Library/Developer/Xcode/DerivedData/MyProject-gfnmwygetouofcguhjlnrmdzrhbp/Build/Products/Debug-iphonesimulator/SwiftyRSA/SwiftyRSA.framework.dSYM':

2) That command depends on command in Target 'SwiftyRSA' (project 'Pods'): script phase “[CP] Copy dSYMs”

Multiple commands produce '/Users/ABCD/Library/Developer/Xcode/DerivedData/MyProject-gfnmwygetouofcguhjlnrmdzrhbp/Build/Products/Debug-iphonesimulator/PromiseKit/PromiseKit.framework.dSYM':

   CocoaPods : 1.10.0
       Xcode : 12.2 (12B45b)
cocoapods-binary           : 0.4.4
plugin 'cocoapods-binary'
MacOS Big Sur 11.0.1

[siggb]

I have the same problem. Although I can use version 0.4.1 on an ad hoc basis.

[tejen]

What's the workaround for this? Due to this issue, I haven't been able to build my projects on Big Sur and Xcode 12.2 unless I remove precompiled pods.

Is the accepted workaround to just run gem uninstall cocoapods-binary and then gem install cocoapods-binary -v 0.4.1 to downgrade to 0.4.1? That seems to work for me.

🙏

[siggb]

Yeah, kind of. I updated my Gemfile to this:

source 'https://rubygems.org'
gem 'cocoapods', '~> 1.10.0'
gem 'cocoapods-binary', '0.4.1'

[geraldeersteling]

Same issue here, but downgrading to 0.4.1 didn't help me...

[kingnight]

You can fix this by hand ，for example
Pods/Target Support Files/AFNetworking/AFNetworking-copy-dsyms-output-files.xcfilelist

Delete duplicate lines，left only one line ${DWARF_DSYM_FOLDER_PATH}/AFNetworking.framework.dSYM

[tejen]

@kingnight nice yeah that works as well 🔥 Cumbersome to delete all duplicate lines in all output-files.xcfilelist and input-files.xcfilelist files, but surprised the issue was that simple.

[scottasoutherland]

If you want to fix this automatically you can put this in your Podfile

post_integrate do |installer|
  patch_cocoapods_binary_dsyms(installer)
end

def patch_cocoapods_binary_dsyms(installer)
  installer.generated_projects.each do |project|
    project.targets.each do |target|
      target.shell_script_build_phases.each do |phase|
        phase.input_file_list_paths.each do |file_list_path|
          dedupe_file_list(file_list_path)
        end
        
        phase.output_file_list_paths.each do |file_list_path|
          dedupe_file_list(file_list_path)
        end
      end
    end
  end
end

def dedupe_file_list(file_list_path)
  file_list_path = file_list_path.delete_prefix "${PODS_ROOT}"
  file_list_path = File.join(PODS_DIR, file_list_path)
  contents = File.readlines(file_list_path, chomp: true)
  contents = contents.uniq
  File.open(file_list_path, "w") do |file|
    file.puts contents
  end
end

[dinghaoz]

besides the "Multiple commands produce" issue, there is a backslash missing in every *-copy-dsyms.sh file:

"${DERIVED_FILES_DIR}" => "${DERIVED_FILES_DIR}/"

Based on @scottasoutherland's code, I patched it with

def patch_cocoapods_binary_dsyms(installer)
  installer.generated_projects.each do |project|
    project.targets.each do |target|
      target.shell_script_build_phases.each do |phase|
        
        shell_file = phase.shell_script.strip.gsub!(/\A"|"\Z/, '').delete_prefix "${PODS_ROOT}"
        shell_file = File.join("./Pods", shell_file)
        
        shell_script = File.read(shell_file, chomp: true)
        fixed_shell_script = shell_script.gsub("\"${DERIVED_FILES_DIR}\"", "\"${DERIVED_FILES_DIR}/\"")

        File.open(shell_file, "w") do |f|
          f.write(fixed_shell_script)
        end
        
        phase.input_file_list_paths.each do |file_list_path|
          dedupe_file_list(file_list_path)
        end
        
        phase.output_file_list_paths.each do |file_list_path|
          dedupe_file_list(file_list_path)
        end
      end
    end
  end
end

def dedupe_file_list(file_list_path)
  file_list_path = file_list_path.delete_prefix "${PODS_ROOT}"
  file_list_path = File.join("./Pods", file_list_path)
  
  contents = File.readlines(file_list_path, chomp: true)
  contents = contents.uniq
  File.open(file_list_path, "w") do |file|
    file.puts contents
  end
end

post_integrate do |installer|
  patch_cocoapods_binary_dsyms(installer)
end

@dinghaoz Tried with your approach but im getting these errors.

[!] An error occurred while processing the post-integrate hook of the Podfile.

I think nil case is not handled in the code. Any idea?

[Misa-s]

It worked! Thanks dinghaoz sir!

[Matejy]

@dinghaoz thanks, your solution worked for me as well.

[miquelalvarado]

Hi! @dinghaoz post_integrate script worked for me to solve most of the errors. Somehow there's one remaining one for me:

Multiple commands produce '/Users/ABCD/Library/Developer/Xcode/DerivedData/foo/Build/Products/Debug-iphonesimulator/foo.app/Pods-foo-metadata.plist'

Target 'foo' (project 'foo') has copy command from '/Users/ABCD/Developer/foo/Pods/Pods-foo-metadata.plist' to '/Users/ABCD/Library/Developer/Xcode/DerivedData/foo/Build/Products/Debug-iphonesimulator/foo.app/Pods-foo-metadata.plist'

Target 'foo' (project 'foo') has copy command from '/Users/ABCD/Developer/foo/Pods/_Prebuild/Pods-foo-metadata.plist' to '/Users/ABCD/Library/Developer/Xcode/DerivedData/foo/Build/Products/Debug-iphonesimulator/foo.app/Pods-foo-metadata.plist'

Any idea on how to fix it? 😕
