I checked my podspec, found that it had a subspec named 'metal', and also, there's a real directory named 'Metal', it throwed exception above when executing pod install.
podspec content:
s.subspec 'metal' do |ss|
ss.source_files = [
"MyProject/Metal/Shaders/*.h",
]
end
directory tree:
.
├── MyProject
| ├── ...
│ ├── Metal
| ├── ...
└── MyProject.podspec
the error line : line 445 in group.rb
result = x.path.downcase <=> y.path.downcase
It seems like that x.path is nil
Finally, I changed my subspec name from 'metal' to 'metal1'(different from the directory name), it worked.
What's the problem with Xcodeproj?
Seems like a potential bug yes. Do you have a sample project or test case that shows the issue?
Any update on this? We are experiencing major issues on bitrise. We downgraded to version 1.19.0 (downgraded also cocoapods) to make this work. Also commenting the line at /Users/<user>/.rvm/gems/ruby-2.7.4/gems/xcodeproj-1.21.0/lib/xcodeproj/project/object/group.rb:445 does work, although i don't know if it will cause other unexpected behaviors or unwanted side effects.
Is there any news on this?
fixed by #865
