Logs

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':flutter:copyFlutterAssetsRelease' (type 'Copy').
  - Gradle detected a problem with the following location: '/home/strongville/[...]/flutter/.android/Flutter/build/intermediates/library_assets/release/out'.
    
    Reason: Task ':flutter:bundleReleaseLocalLintAar' uses this output of task ':flutter:copyFlutterAssetsRelease' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
    
    Possible solutions:
      1. Declare task ':flutter:copyFlutterAssetsRelease' as an input of ':flutter:bundleReleaseLocalLintAar'.
      2. Declare an explicit dependency on ':flutter:copyFlutterAssetsRelease' from ':flutter:bundleReleaseLocalLintAar' using Task#dependsOn.
      3. Declare an explicit dependency on ':flutter:copyFlutterAssetsRelease' from ':flutter:bundleReleaseLocalLintAar' using Task#mustRunAfter.
    
    Please refer to https://docs.gradle.org/8.1/userguide/validation_problems.html#implicit_dependency for more details about this problem.

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --debug option to get more log output.
> Run with --scan to get full insights.

* Get more help at https://help.gradle.org

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

Thanks for the report.
Can you take a look at below links and see if they help in your case ?

This seems to be a workaround that requires amending the files generated by the Flutter SDK (same files that shouldn't be added to version control), is this correct?

These lines were added to .android/Flutter/build.gradle:

afterEvaluate {
    bundleDebugLocalLintAar.dependsOn copyFlutterAssetsDebug
    bundleReleaseLocalLintAar.dependsOn copyFlutterAssetsRelease
}

This solves the exception previously shown above. Is there a way for this to be included by default when generating files on Flutter SDK? I see the referred comment was posted several months ago, is there a blocking issue or major refactor awaiting?

Personally, I'd like to depend on as less workarounds as possible, to be able that the team members can configure the project more easily.

Also, to be able to use AGP 8.0 we require Gradle 8, so, for this case, downgrading Gradle versions to the one where this is a warning instead of an exception, isn't a choice either, unfortunately.

darshankawar · 2023-06-30T05:29:51Z

Thanks for the update. Keeping this issue open based on the error received and above feedback.

camsim99 · 2023-07-06T18:14:52Z

To whoever takes this bug: this is probably a problem we have with other tasks. When fixing this bug, identify anything in the code that can allow us to audit the rest of our code for similar problems.

bartekpacia · 2023-07-13T22:50:36Z

To add some more info: the problem lies in the wrongly-setup dependencies between Flutter Gradle Plugin's own Gradle tasks. The issue and comments @darshankawar linked to above are good starting points for someone to start working on it. The final result will be probably similar to #121958 (this is the PR that fixes a similar error for full-Flutter apps).

@strongville

This seems to be a workaround that requires amending the files generated by the Flutter SDK...

I have the same problem, so thank you so much for that workaround. It helped me with the DEBUG build.

However, there is a problem with the RELEASE build.
Android Studio's gradle project sync failed with exception
Could not get unknown property 'copyFlutterAssetsRelease' for project ':flutter' of type org.gradle.api.Project

here
afterEvaluate { bundleReleaseLocalLintAar.dependsOn copyFlutterAssetsRelease }

Unfortunately, I have no idea how to fix this. Possibly you faced the same problem?
Thanks you!

I modified the compilation script, temporarily compiled successfully

SoftickSupport · 2023-09-04T09:46:20Z

@sunchangtan thank you so much! it helped.

afterEvaluate {
    bundleDebugLocalLintAar.dependsOn copyFlutterAssetsDebug
    bundleReleaseLocalLintAar.dependsOn copyFlutterAssetsRelease

Where exactly does this go? I tried adding this to my build.gradle as a workaround but I get this error

`A problem occurred configuring root project 'Timing'.

A problem occurred configuring project ':flutter'.
Could not get unknown property 'copyFlutterAssetsDebug' for extension 'flutter' of type FlutterExtension.
`

SoftickSupport · 2023-09-18T11:04:01Z

@jnstahl Use the workaround from sunchangtan. It helps.

SoftickSupport · 2023-09-30T15:29:16Z

@sunchangtan @jnstahl
I added the double quotes to the original workaround:

afterEvaluate {
    bundleDebugLocalLintAar.dependsOn "copyFlutterAssetsDebug"
    bundleReleaseLocalLintAar.dependsOn "copyFlutterAssetsRelease"
}

Now, I don't need to change Flutter sources.
Unfortunately, the double quotes only helped me with my Jenkins (Linux) build.
I still need to change Flutter sources on my Windows work PC.

I hope this will be helpful.

leon2017 · 2023-10-08T12:09:15Z

project build.gradle add this:

subprojects { sub ->
    sub.afterEvaluate { proj ->
        if (proj.name == 'flutter') {
            def flutterProject = project(':flutter')
            flutterProject.afterEvaluate {
                bundleDebugLocalLintAar.dependsOn "copyFlutterAssetsDebug"
                bundleReleaseLocalLintAar.dependsOn "copyFlutterAssetsRelease"
            }
        }
    }
}

#137370 should land shortly, and fixed this issue in my local reproduction. There are multiple workflows to run add to app projects though, so please let me know if it doesn't fix it for you

Fixes #129471. Does so by doing a very similar thing that is done by #121958, but for a task that is specific to the add to app build process.
