Not able to Build Android

[VikasAgrawal-04]

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

Just Build The application and it will fail at Building android.

Expected results

Build should be successful as it's working on my local device.

Actual results

It's failing to build the android aab. And I am using /Library/Java/JavaVirtualMachines/zulu-21.jdk/Contents/Home for Java version and tried upgrading to 23.jdk but gave me incompatible version for gradle but works on my Mac with java 23 version.

Hello @VikasAgrawal-04,
I found below error message in your logs:

* What went wrong:
Could not open settings generic class cache for settings file '/Users/builder/clone/android/settings.gradle' (/Users/builder/.gradle/caches/8.1.1/scripts/6w4sibxqp3f4qjgf89olt5q7b).
> BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 65

Based on discussions online, this issue is likely due to Java 21 not being supported. Some users have resolved it by either downgrading to JDK 11 or upgrading their Gradle version.

Here’s a relevant StackOverflow thread:

Additionally, a similar issue was reported for React Native Android, which may apply to your Flutter app as well:

Please can you try adjusting your JDK or Gradle version to resolve the issue?

Hey @VikasAgrawal-04,
I just checked through your team builds and can see your recent build creates android but the publishing step failed with below message:

Google Play failed to upload artifacts. Version code 93 has already been used.: {
    "error": {
        "code": 403,
        "message": "Version code 93 has already been used.",
        "status": "PERMISSION_DENIED"
    }
}

You can either add --build-number=UPDATED_VERSION_CODE use an updated version code not in the stores currently in your pubspec.yaml file. You can also retrieve the latest version code in the stores and increment it as described here - https://docs.codemagic.io/knowledge-codemagic/build-versioning/.
