Git operation fails while downloading mbed library

Mbed Studio Bugs

When creating a new project or updating a library in an existing project, the download of the mbed library fails. A portion of my mbed-studio.log:

I am able to workaround this with mbed-cli.

Hi Jonathan,

Thank you for reporting this issue. I’m glad that a temporary mbed-cli workaround works for you. We believe that it may happen because of the version of git installed on your system. Can you check and let us know the version of git you have got installed? Please feel free to also send us logs to studio@mbed.com. It will help us in investigating this issue.

Mbed Studio is shipped with Git but is using it only when Git is not present on the system or the version of it is too old.
In upcoming minor release of Mbed Studio we improved Source Control and Library Management. We switched also to always use bundled version of Git. You can expect that release soon.

Thanks,
Arek - Mbed Studio team

I am using version 2.24.1.2 available from Chocolatey Software | Git 2.39.0

My Git setup has not changed recently. Git operations with Mbed Studio were working a few weeks ago.

Hi Jonathan,

Version 2.24.1.2 of Git for Windows has a bug where its handling of invalid file paths is unnecessarily strict. The mbed-os repository history has an invalid file path that was added and removed a long time ago, so this version of Git cannot clone mbed-os.

The issue is reported in Git-for-Windows here: Git 2.24 breaks existing repositories: filename in tree entry contains backslash · Issue #2435 · git-for-windows/git · GitHub.

Work-arounds:

  • Disable the NTFS protections in Git (see the GitHub issue)
  • Downgrade Git to 2.24.0

Or continue using mbed-cli for now and wait for the next Mbed Studio version as suggested by Arek.

Hope that helps,
Matthew - Mbed Studio team

Thanks for the info! As a note, I just hit this installing mbed studio on a clean machine (where I had also just installed Git for Windows from their download page). So, anyone spinning up new machines or setups on Windows is probably going to hit this. Good to know that there are workarounds.

Downgrading Git worked for me. Thanks.

In case anyone else comes across this, Git for Windows 2.25.0 has just been released and includes a fix for this issue.
