CMake Error: file failed to open for reading (Permission denied) in extensions.cmake when running Twister in CI/CD pipeline

Problem
I'm encountering a CMake permission error when running Zephyr's Twister test framework in my CI/CD pipeline. The test execution fails with the following error:
CMake Error at zephyr/cmake/modules/extensions.cmake:1080 (file):
file failed to open for reading (Permission denied):

Environment
OS: Windows (CI/CD Runner)
Zephyr Version: 3.6
Twister Command: python zephyr/scripts/twister --device-testing --hardware-map "map.yml" -T app/examples -e build -O app/twister-out -c -vv

Expected Behavior
Twister should successfully build and run tests in the CI/CD pipeline without permission errors.

Support Required:
What configuration or workaround is required to resolve the windows permission issues with Twister in CI/CD

Thanks in advance for your support!

Hi Team,

Just following up on the issue reported regarding the CMake permission error encountered while running Zephyr's Twister test framework in our Windows-based CI/CD pipeline.

As a quick recap:

Zephyr Version: 3.6
Command Used:
python zephyr/scripts/twister --device-testing --hardware-map "map.yml" -T app/examples -e build -O app/twister-out -c -vv
Issue:
CMake Error at zephyr/cmake/modules/extensions.cmake:1080 (file): file failed to open for reading (Permission denied)
Expected Behavior:
Twister should build and run tests without permission issues in the CI/CD environment.
Would appreciate any guidance or configuration suggestions to resolve this.

Thanks again for your support!

Best regards,

Hi Zephyr Team,

I hope this message finds you well. I wanted to follow up on my discussion posted last week regarding a CMake permission error we're experiencing with Twister in our Windows CI/CD environment.

Quick Summary:

Issue: CMake Error at zephyr/cmake/modules/extensions.cmake:1080 - file failed to open for reading (Permission denied)
Environment: Windows CI/CD Runner, Zephyr v3.6
Command: python zephyr/scripts/twister --device-testing --hardware-map "map.yml" -T app/examples -e build -O app/twister-out -c -vv

This issue is blocking our automated testing pipeline, and any guidance on Windows-specific configurations or potential workarounds would be greatly appreciated. I understand the community is busy, but if anyone has encountered similar permission issues with Twister on Windows or has suggestions for troubleshooting, I'd be very grateful for your insights.

Thank you for your time and continued support of the Zephyr project!

Best regards,
Namrata Gagare

The first thing that comes to my mind is that the file paths becoming too long for Windows to properly handle.

I suggest you to check the build.log under twister-out to get more detailed information regarding the failure.

Hi,

Thank you for responding.

The build.log does not specify anything related to long file paths.
We initially faced long file path issue which we fixed by adding --short-build-path in twister cmd locally. We will enable this on CI/CD environment and continue our investigation. I will get back to you in next week.

Thanks,
