"Build files not found" on Flutter for Windows build

[marcoancona]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

I am running a build for Windows of my Flutter app. The build step seems to work correctly by the subsequent step of MSIX bundling fails.

The error is Build files not found at C:\Users\builder\clone/build/windows/runner/Release, first run "flutter build windows" then try again. This seems suspicious because the build has indeed worked according to previous logs and because the path combines slashes and backslashes.

Expected results

The build of MSIX succeeds.

Actual results

== Building for Windows ==

> flutter.BAT config --enable-windows-desktop
Setting "enable-windows-desktop" value to "true".

You may need to restart any open editors for them to read new settings.

> flutter.BAT build windows --release

Hi @marcoancona, to configure the misx, please add msix_config to your pubspec.yaml

[himesh-cm]

It should work alright now. Please try to re-run the build again and let us know if you still face any issues.

Hi @marcoancona, I'm tentatively closing the discussion since we haven't heard back from you. You can open the discussion again by replying to this message.
