Summary
Unix-style line endings in files are being converted to windows-style (CRLF) line endings when Git checkout is performed on Bamboo Windows elastic agent.
Environment
- Windows elastic agent
- Git for Windows
Cause
The default value for Git for Windows for core.autoclrf is true after installation. Bamboo stock elastic images use the default for the Git for Windows installer. This means that when a Git checkout is performed on a Windows machine the LF line endings are converted to CRLF.
Solution
If this is not desirable there are a few options:
Option 1:
Configure a custom Bamboo elastic agent image with core.autoclrf set to false globally before snapshotting it:

Option 2:
Set git config --global core.autoclrf false in a Script task before the source-code checkout on builds that execute on Windows agents.
Option 3:
Add a .gitattributes to your repository which controls line ending styles and end of line normalization through the text and eol attributes:
