[Bug]: Task ':app:lintAnalyzeDebug' uses this output of task ':app:copyReactNativeVectorIconFonts' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.

Which package are you using?

@react-native-vector-icons/*

What platform(s) does this occur on?

Fix:

Under "android.applicationVariants.all { def variant ->" in "fonts.gradle" add:

def lintAnalyzeTask = tasks.findByName("lintAnalyze${targetName}") lintAnalyzeTask?.dependsOn(copyReactNativeVectorIconFonts)

@makhoulshbeeb Can you migrate to @react-native-vector-icons/* v11.x

It copies the fonts in a different way that solves this issue

[MatthieuCutin]

Hi @johnf, I'm facing the same issue with react-native-vector-icons v10.2.0.

I can't migrate to @react-native-vector-icons/ v11.x since I'm using react-native-vector-icons as a dependency of React Native Elements.

Is there a way to properly copy the fonts without migrating?

[johnf]

@MatthieuCutin Would you be able to share a repro?

We've come across this issue in 10.x a few times, but it's hard to nail down why it affects some folks and not others

For anyone still facing this issue, the following solved it for a project I work on and may work for you. In my case we had a different task that was flagged as being dependent oncopyReactNativeVectorIconFonts, but the error was nearly identical:

* What went wrong:
A problem was found with the configuration of task ':app:copyReactNativeVectorIconFonts' (type 'Copy').
  - Gradle detected a problem with the following location: '{PROJECT_PATH}/android/app/build/intermediates/ReactNativeVectorIcons/fonts'.

    Reason: Task ':app:generateReleaseStoreLintVitalReportModel' uses this output of task ':app:copyReactNativeVectorIconFonts' 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 ':app:copyReactNativeVectorIconFonts' as an input of ':app:generateReleaseStoreLintVitalReportModel'.
      2. Declare an explicit dependency on ':app:copyReactNativeVectorIconFonts' from ':app:generateReleaseStoreLintVitalReportModel' using Task#dependsOn.
      3. Declare an explicit dependency on ':app:copyReactNativeVectorIconFonts' from ':app:generateReleaseStoreLintVitalReportModel' using Task#mustRunAfter.

    For more information, please refer to https://docs.gradle.org/8.10.2/userguide/validation_problems.html#implicit_dependency in the Gradle documentation.

To fix this, as the "Possible solutions" section indicates, you can try to declare an explicit dependency on the :app:copyReactNativeVectorIconFonts task for the :app:generateReleaseStoreLintVitalReportModel task. In OPs case, the task would be :app:lintAnalyzeDebug, but the solution is the same.

Within ./android/app/build.gradle, try adding the following to declare the dependency for the task:

android {
    // ...existing code...

    tasks.whenTaskAdded { task ->
        // Change the task name here to the task from your error message, for OP this would be 'lintAnalyzeDebug'
        if (task.name == 'generateReleaseStoreLintVitalReportModel') { 
            task.dependsOn 'copyReactNativeVectorIconFonts'
        }
    }
}

This code snippet ensures that the generateReleaseStoreLintVitalReportModel task depends on the copyReactNativeVectorIconFonts task, which should resolve the issue.

Hope that helps!

Please upgrade to RNVI 12.x which takes a different approach. You'll need to follow the migration guide
