Missing folder during dependency install on build system

[jbelkins]

Describe the bug

Preview builds have intermittent build failures when building AWSSDKSwiftCLI due to missing folders, i.e.:

warning: 'swift-llbuild': ignoring broken symlink /codebuild/output/src3290271464/src/aws-sdk-swift/AWSSDKSwiftCLI/.build/checkouts/swift-llbuild/lib/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm/Demangle/include/llvm
error: 'swift-llbuild': The folder “ADT” doesn’t exist.

[Container] 2024/08/15 23:13:18.317969 Phase context status code: COMMAND_EXECUTION_ERROR Message: Error while executing command: swift run AWSSDKSwiftCLI test-aws-sdk ../ --batches 10. Reason: exit status 1

It is noted that the swift-llbuild dependency version in use does some weird stuff with symlinks, which are corrected in later versions.

Expected Behavior

AWSSDKSwiftCLI tools should build & run every time and on all platforms.

Current Behavior

AWSSDKSwiftCLI fails intermittently as described.

Reproduction Steps

Look at build logs from previous preview builds.

Possible Solution

swift-llbuild seems to be linked only because it is a dependency of AWSSDKSwiftCLI dependency SwiftPM. SwiftPM seems to be used only for the Version type, which should be easily reproducible in the AWSSDKSwiftCLI project.

So, investigate removing SwiftPM entirely as a dependency of the CLI tools.

Additional Information/Context

No response

AWS SWIFT SDK version used

main

Compiler and Version used

Moving to Blocked while we wait to see if build failures due to this issue stop occurring.

Closing the ticket as no new preview build was observed with this cause the week of 8/19/24.
