Android workaround

So, I found a way to fix this problem in local builds and CI builds:
Create any “Editor” folder in Assets
Create C# script and copy code from below

using System.IO;
using System.Threading.Tasks;
using UnityEditor;
using UnityEditor.Build;
using UnityEditor.Build.Reporting;

public class AndAnotherOneFixForFirebase : IPostprocessBuildWithReport, IPreprocessBuildWithReport
{
    public int callbackOrder => 0;

    public void OnPostprocessBuild(BuildReport report)
    {
        if (report.summary.platform != BuildTarget.Android)
            return;

        DeleteSpecificAar();
    }

    private static void DeleteSpecificAar()
    {
        string pathToAar = "Assets/Plugins/Android/com.google.firebase.firebase-common-ktx-20.3.3.aar";

        if (File.Exists(pathToAar))
        {
            File.Delete(pathToAar);
            AssetDatabase.Refresh();
            UnityEngine.Debug.Log("Specific .aar file deleted successfully.");
        }
        else
        {
            UnityEngine.Debug.LogWarning("Specified .aar file not found.");
        }
    }

    public void OnPreprocessBuild(BuildReport report)
    {
        WaitForBuildStart(report);
    }

    private static async void WaitForBuildStart(BuildReport report)
    {
        if (report.summary.platform != BuildTarget.Android)
            return;

        string pathToAar = "Assets/Plugins/Android/com.google.firebase.firebase-common-ktx-20.3.3.aar";

        await WaitForFile(pathToAar);
        
        if (File.Exists(pathToAar))
        {
            File.Delete(pathToAar);
            AssetDatabase.Refresh();
            UnityEngine.Debug.Log($"{pathToAar} deleted.");
        }
        else
        {
            UnityEngine.Debug.LogWarning($"{pathToAar} not found.");
        }
    }

    private static Task WaitForFile(string path)
    {
        return Task.Run(() =>
        {
            while (!File.Exists(path))
            {
                Task.Delay(500).Wait();
            }
        });
    }
}

It seems the bug in download_artifacts.gradle. I have a project and among transitive dependencies for different libraries there are versions: firebase-common:20.1.0, 20.2.0, 20.3.3 in project. and download_artifacts.gradle finally resolves them all as "firebase-common:+ " and it means it got last 20.4.0 version, that has conflict with firebase-common-ktx-20.3.3.

if I change resolution strategy to patching mainTemplate.gradle then all works fine and gradle resolves different dependencies (20.1.0, 20.2.0, 20.3.3) as 20.3.3 as expected, because it’s highest version for this package through all libraries.
