Gradle task dependency issues

[ansman]

This is a re-open of #5083 as the issue is still happening

@argzdev @mrober Still reproduce in 2.9.7

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':app:generateCrashlyticsSymbolFileRelease' (type 'GenerateSymbolFileTask').
  - Gradle detected a problem with the following location: '/home/vsts/work/1/s/app/build/intermediates/merged_native_libs/release/out/lib'.
    
    Reason: Task ':app:generateCrashlyticsSymbolFileRelease' uses this output of task ':app:mergeReleaseNativeLibs' 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:mergeReleaseNativeLibs' as an input of ':app:generateCrashlyticsSymbolFileRelease'.
      2. Declare an explicit dependency on ':app:mergeReleaseNativeLibs' from ':app:generateCrashlyticsSymbolFileRelease' using Task#dependsOn.
      3. Declare an explicit dependency on ':app:mergeReleaseNativeLibs' from ':app:generateCrashlyticsSymbolFileRelease' using Task#mustRunAfter.
    
    For more information, please refer to https://docs.gradle.org/8.2.1/userguide/validation_problems.html#implicit_dependency in the Gradle documentation.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

This is possibly only an issue when enabling the configuration cache

Another seems to be that if you are building multiple variants in a single invocation, the InjectBuildIdsTask uses the output from all merge native libs tasks.

As a workaround you can add this (for Kotlin build scripts)

afterEvaluate {
    // This provides a workaround for https://github.com/firebase/firebase-android-sdk/issues/5629
    tasks.withType<InjectBuildIdsTask>().configureEach {
        mustRunAfter(tasks.withType<MergeNativeLibsTask>())
    }
}

Hi, I have re-checked and looks like all issues with InjectBuildIds fixed.
We use crashlytics gradle 2.9.9

Please note, that additional fixed provided in scope of this issue:
#5122

Thanks for your time!

Thanks for confirming!
