Execution failed for task ':app:checkDebugAarMetadata'.

[cgfischer]

I have a flutter application that has been building reliably but today fails to build with this error (see details below). I successfully built this application yester on several Windows 10 development machines. The same code now fails (starting July 1) on those same development machines even though the code didn't change and now new software was installed (unless there was an automatic Windows update?).

The build failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetifier to solve the incompatibility.

Hi @cgfischer
Please provide complete flutter run -v, your pubspec.yaml, your build.gradle a minimal reproducible code sample that does not use 3rd party plugins, your complete flutter run -v logs running the minimal code sample

Thank you

[cgfischer]

I was able to resolve this by updating the compile SDK version to 30 and updating a hand full of plugins to more recent versions. I’m still not sure why this was necessary and found the unexpected road bump somewhat frustrating.
