'testExamplePackageDealer' fails due to compilation error on Windows platform

[kcieplak]

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

The 'testExamplePackageDealer' clones code from 'https://github.com/apple/example-package-dealer'

try sh("git\(ProcessInfo.exeSuffix)", "clone", "https://github.com/apple/example-package-dealer", packagePath)
let build1Output = try sh(swiftBuild, "--package-path", packagePath).stdout

The code fails to build when on the Windows platform.
