Copy command fails on mounted drives under Linux

[StefanCosminR]

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

• Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands, swift build, swift test, swift package etc.

Description

I have a shared folder between MacOS and Ubuntu 22.04 under Parallels. The folder appears as a mounted drive in Ubuntu. If the package has a resource with copy command, the build fails. Copying the project to a folder local to Ubuntu, such as /home, the build succeeds.

Expected behavior

I expect the build to succeed.

Actual behavior

The build fails with a hard to debug error.

Building for debugging...
error: Error Domain=NSCocoaErrorDomain Code=512 "(null)"

Steps to reproduce

1. Under MacOS, create an empty folder.
2. Run: swift package init --type executable
3. Create a file under Sources
4. Add the file as a resource to the target (example at the end)
5. Create an Ubuntu VM under Parallels (Maybe it can be reproduced on a real machine with a mounted drive, but I don't have that kind of setup to test on)
6. Go to VM settings > Sharing > Share custom Mac folders with Linux > Select the previously create folder
7. Under Ubuntu, with Swift 6.0, run swift build on the shared folder

        // Targets can depend on other targets in this package and products from dependencies.
        .executableTarget(
            name: "CopyFileBug",
            resources: [
                .copy("test.txt")
            ]
        ),
    ]
)
