Hi @kashif789us,

Thanks for reporting this issue. I was also able to replicate this issue using the quickstart with the same Unity version. Here is the error message I got for reference:

I'll be marking this as a bug for now. Let me discuss this with the team, and we'll get back to you once we have updates.

Unity editor version: 2021.2.0f1
Firebase Unity SDK version: 8.7.0
Source you installed the SDK: .unitypackage
Problematic Firebase Component: Analytics / App / Auth / Crashlytics / Database / Firestore / Storage
Additional SDKs you are using: Error is replicated in an empty project with only Firebase
Platform you are using the Unity editor on: PC
Platform you are targeting: Android
Scripting Runtime: IL2CPP

Hello, I am getting the same issues on a slightly different editor and Firebase version.
The build breaks with the Custom Main Gradle Template enabled. In the Gradle file every dependency that has "-unity" causes it to fail during build.
I was able to comment them out 1 by 1 and build successfully, but that's not the point.

Sample failure message:
FAILURE: Build failed with an exception.

• What went wrong:
  Could not determine the dependencies of task ':launcher:lintVitalRelease'.

Could not resolve all artifacts for configuration ':launcher:debugRuntimeClasspath'.
Could not find com.google.firebase:firebase-app-unity:8.7.0.

Hi all,

Thanks to @deetmo, this appears to be a regression from the Unity side.

https://issuetracker.unity3d.com/issues/android-template-variable-star-star-dir-unityproject-star-star-is-not-properly-substituted-when-exporting-a-gradle-project?_ga=2.122711496.294034660.1640030138-1623586750.1636598340

Their fix has been integrated to 2022.1.0a13 but it is still in-review for 2021.2.

If you are experiencing this issue, here are some workarounds

• Downgrade Unity to 2021.1
• Use the workaround @deetmo provided here. [Bug] Unity 2021.2 gradle fails to resolve local maven path googlesamples/unity-jar-resolver#478 (comment)

It would be rather challenging to provide a patch for this in EDm4U but we'll see what we can do.

Hi, all

can anyone suggest to me a solution for the same?

Still relevant for Unity 2022 and 2023. I managed to make it work on 2021, but not on the latest ones. I've spent 4 days already on it and became a master in gradle files configuration, but still can not fix it. Any help?

@CodeProf14 I tried that also, but it still doesn't work!

Let me know if u find any solution

Same here after trying to upgrade to Unity 2022

If you are still having this issue and can't update Unity, place this script into an Editor folder:

using System.IO;
using UnityEditor;
using UnityEditor.Build;
using UnityEditor.Build.Reporting;
using UnityEngine;

    private string originalMainTemplateContents = null;

    public void OnPreprocessBuild(BuildReport report)
    {
        originalMainTemplateContents = null;

        if (File.Exists(GradleMainTemplatePath))
        {
            originalMainTemplateContents = File.ReadAllText(GradleMainTemplatePath);
            string projectDir = Path.GetDirectoryName(Application.dataPath);
            Debug.Log($"To fix a bug, replacing **DIR_UNITYPROJECT** with \"{projectDir}\" in the gradle template file \"{GradleMainTemplatePath}\"."
                  " This fix can be removed after updating to Unity 2021.2.8 or later");
            string fixedContents = originalMainTemplateContents.Replace("**DIR_UNITYPROJECT**", projectDir);
            File.WriteAllText(GradleMainTemplatePath, fixedContents);
        }
    }

    public void OnPostprocessBuild(BuildReport report)
    {
        if (!string.IsNullOrEmpty(originalMainTemplateContents))
        {
            File.WriteAllText(GradleMainTemplatePath, originalMainTemplateContents);
            originalMainTemplateContents = null;
        }
    }
}

Same here after migration from 2021.3.16 to 2022.3.2

I encountered a similar issue with Unity Editor version 2021.3.9f1 and all other 2021 Unity versions while building the APK. However, after some troubleshooting, I found a workaround that might be helpful to others facing the same problem.

Solution:

1. Unity Version: I experienced the issue with Unity LTS version 2021.3.9f1 and other 2021 versions.
2. Successful Build: After switching to Unity LTS version 2022.3.9f1, the build process worked without any problems.

I hope this information is helpful for others facing the same problem. Please let me know if you need any further details.

I got error while build in Unity android port (and two more similar errors for files: firebase-messaging-unity-11.6.0.pom and google-signin-support-1.0.4.pom):

But the problem is that I have these files! They are located along one of the paths from the search list. in the generated directory:
c:\Unity\projects\X\Assets\GeneratedLocalRepo\Firebase\m2repository\com\google\firebase\firebase-app-unity\11.6.0\firebase-app-unity-11.6.0.pom

Why am I getting an error? What could be the reason?
