swift-log: xcodebuild DocC error with Xcode 14

Expected behavior

My team and I normally build our app with a CLI command like this:

xcodebuild -quiet -workspace MyApp.xcworkspace -scheme MyApp

Actual behavior

After updating Xcode from 13 to 14, running our xcodebuild command now fails with the following error:

2022-09-16 11:05:28.019 xcodebuild[47484:558966] [MT] IDEFileReferenceDebug: [Load] <IDESwiftPackageCore.IDESwiftPackageSpecialFolderFileReference, 0x600000287c00: name:Documentation.docc path:group:Documentation.docc> Failed to load container at path: /Users/username/Library/Developer/Xcode/DerivedData/MyApp-darnasgcpehipbceilnyjlqsmpxt/SourcePackages/checkouts/swift-log/Sources/Logging/Documentation.docc, Error: Error Domain=com.apple.dt.IDEContainerErrorDomain Code=6 "Cannot open "Documentation.docc" as a "Swift Package Folder" because it is already open as a "Folder"." UserInfo={NSLocalizedDescription=Cannot open "Documentation.docc" as a "Swift Package Folder" because it is already open as a "Folder".}

Steps to reproduce

Create a brand new Xcode 14 project targeting iOS with Swift/SwiftUI
Under Project Settings, add swift-log (https://github.com/apple/swift-log.git) as a Package Dependency
Navigate to the project’s root folder in Terminal
Execute xcodebuild -quiet
This error shows up

If possible, minimal yet complete reproducer code (or URL to code)

I found a related issue on the Swift forums that was posted a few months back: https://forums.swift.org/t/xcode-and-swift-package-manager/44704

I tried modifying the xcodebuild flags for derivedDataPath and clonedSourcePackagesDirPath, but it did not appear to change how this issue was affecting my builds.

@neonichu @tomerd confirming that xcodebuild -scheme <name> works for me. The Docc error messages are not preventing the build to complete.

I’m a bit confused. What is this ‘less / not supported path’ or legacy-style builds for building projects with packages? We use xcodebuild in our CI system, and don’t know any other way to build Xcode workspaces (which uses SPM packages). We are passing the sdk to use, which scheme to use, etc… Is there another way to do this?

for example: /usr/bin/xcodebuild -sdk iphoneos -configuration Release -workspace /Users/agent/azagent-A3/_work/3/s/app.xcworkspace -scheme MyScheme build ENABLE_BITCODE=NO CODE_SIGN_STYLE=Automatic | /usr/local/bin/xcpretty -r junit --no-color If there are other ways to do this better, I gladly hear it.
