[Bug] Gradle build fails on Unity 2021 when custom gradle templates are enabled

[kashif789us]

[REQUIRED] Please fill in the following fields:

• Unity editor version: 2021.2.6f1
• Firebase Unity SDK version: 8.6.2
• Source you installed the SDK: .unitypackage
• Problematic Firebase Component: Analytics
• Other Firebase Components in use: None
• Additional SDKs you are using: Facebook, None
• Platform you are using the Unity editor on: Mac
• Platform you are targeting: Android
• Scripting Runtime: IL2CPP

[REQUIRED] Please describe the issue here:

My APK fails during building gradle with following error:

CommandInvokationFailure: Gradle build failed.
/Applications/Unity/Hub/Editor/2021.2.6f1/PlaybackEngines/AndroidPlayer/OpenJDK/bin/java -classpath "/Applications/Unity/Hub/Editor/2021.2.6f1/PlaybackEngines/AndroidPlayer/Tools/gradle/lib/gradle-launcher-6.1.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "assembleRelease"

Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8

FAILURE: Build failed with an exception.

• What went wrong:
  Could not determine the dependencies of task ':unityLibrary:compileReleaseAidl'.

Could not resolve all task dependencies for configuration ':unityLibrary:releaseCompileClasspath'.
Could not find com.google.firebase:firebase-analytics-unity:8.6.2.
Required by:
project :unityLibrary
Could not find com.google.firebase:firebase-app-unity:8.6.2.

Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?
What's the issue repro rate?

Yes, 100% when I enable mainTemplate.gradle and disable Auto Resolution in Android Resolver Settings.

What happened? How can we make the problem occur?

1. Run Analaytics Quick start in Unity 2021.2.6f1.
2. Enable mainTemplate.gradle, launcherTemplate.gradle, baseProjectTemplate.gradle and gradleTemplate.properties
3. Build APK.

It builds fine If I don't enable gradle scripts and enable Auto Resolution.
It is also building without any problem on older Unity versions with custom gradle files.

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.

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?

[korsour]

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?
