Error running `utils/update-checkout --clone-with-ssh`

James_Dempsey · June 23, 2024, 8:51pm

I am attempting to follow the Getting Started instructions at swift/docs/HowToGuides/GettingStarted.md at main · swiftlang/swift · GitHub.

When I run utils/update-checkout --clone-with-ssh

I get the error listed below attempting to checkout out the icu project.

Is this a known error?
Is there a workaround?

Thanks in advance for any assistance.

The above exception was the direct cause of the following exception:

bug update-checkout utils unexpected error swift 6.0

### Description https://github.com/apple/swift/blob/main/docs/HowToGuides/Get…tingStarted.md#cloning-the-project Hi! I just tried following the `cloning-the-project` steps on a new (vanilla) `swift` checkout (from latest `main`). I'm seeing some errors on console: ``` Traceback (most recent call last): File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/multiprocessing/pool.py", line 125, in worker result = (True, func(*args, **kwds)) File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/multiprocessing/pool.py", line 48, in mapstar return list(map(*args)) File "/Users/rick/Developer/swift-project/swift/utils/update_checkout/update_checkout/update_checkout.py", line 376, in obtain_additional_swift_sources shell.run(['git', '--git-dir', File "/Users/rick/Developer/swift-project/swift/utils/swift_build_support/swift_build_support/shell.py", line 257, in run raise eout Exception: ['git', '--git-dir', '/Users/rick/Developer/swift-project/icu/.git', '--work-tree', '/Users/rick/Developer/swift-project/icu', 'checkout', 'maint/maint-69'] ``` I tried running `cloning-the-project` again and see similar errors: ``` [icu] + git checkout maint/maint-69 [icu] error: Your local changes to the following files would be overwritten by checkout: [icu] .ci-builds/.azure-exhaustive-tests.yml [icu] .ci-builds/.azure-pipelines.yml [icu] .ci-builds/data-filter.json ... [icu] error: The following untracked working tree files would be overwritten by checkout: [icu] .appveyor.yml [icu] .ci-builds/.azure-valgrind.yml [icu] .github/workflows/icu_ci.yml ... [icu] ic ``` Anyone seen these errors before or know the steps to work around and test building `swift` locally? I'm on Apple Silicon BTW. Thanks! ### Reproduction ```shell mkdir swift-project cd swift-project git clone https://github.com/apple/swift.git swift cd swift utils/update-checkout --clone-with-ssh ``` ### Expected behavior `utils/update-checkout` succeeds and installs deps with no errors. ### Environment ```shell uname -a Darwin C97RX2X127.local 23.2.0 Darwin Kernel Version 23.2.0: Wed Nov 15 21:55:06 PST 2023; root:xnu-10002.61.3~2/RELEASE_ARM64_T6020 arm64 ``` ```shell sw_vers ProductName: macOS ProductVersion: 14.2.1 BuildVersion: 23C71 ``` ```shell git --version git version 2.39.3 (Apple Git-145) ``` ```shell git remote -v origin git@github.com:apple/swift.git (fetch) origin git@github.com:apple/swift.git (push) git branch * main git rev-parse HEAD e7475c89edb66a26d762c6e9a24c9bdb1a80b87a ``` ### Additional information _No response_

I believe it's this one.

Thank you @vanvoorden. The workaround listed in the issue of skipping checking out the ICU project avoided the error.

@James_Dempsey Want to help land this diff to update the instructions?

James_Dempsey · June 24, 2024, 7:59pm

@vanvoorden I'm not sure what I am able to do since I don't have commit access to the repository. I left a review note that the workaround worked for me on macOS as of yesterday.
