Android App Bundle (.aab) FileNotFoundException when building

Hi,
I just updated the Unity to version 2018.3.0f2 and tried building the .aab file from my project. Unity said the build was successful, but it also threw this error and there is no build.

Any ideas how to solve this or what could be the issue?

FileNotFoundException: Temp/gradleOut/build/outputs/bundle/release/gradleOut.aab does not exist
System.IO.File.Move (System.String sourceFileName, System.String destFileName) (at /Users/builduser/buildslave/mono/build/mcs/class/corlib/System.IO/File.cs:318)

UnityEngine.GUIUtilityrocessEvent(Int32, IntPtr)

 

Same thing happening here, there is no aab file in Temp/gradleOut/build/outputs/bundle/release/.

 

Hi,

Are you using a custom gradle file ? (Player Settings > Checkbox named "Custom Gradle Template")

I had this exact same error, that i eventually managed to fix by updating the content of my mainTemplate.gradle file (which is located in Assets/Plugins/Android ), after comparing it with the default gradle template of Unity 2018.3.1f1 :

[path to Unity]/PlaybackEngines/AndroidPlayer/Tools/GradleTemplates/mainTemplate.gradle


I was so excited by the idea of being able to build an aab file (android aab files allow users to get smaller, more optimized downloads) that i completely forgot to double check the content of the new gradle template

The following thread appeared to be a livesaver to me :

https://forum.unity.com/threads/gradle-error-during-android-building.569113/

(check ScottyB's post)

 

so how do u fixed this error i got this one
FileNotFoundException: Temp\gradleOut\build\outputs\bundle\release\gradleOut.aab does not exist

 

Hi @GodManOmar777, what is your version of unity ?

You need to update the content of your mainTemplate.gradle file (which is located in Assets/Plugins/Android ), by comparing it with the default gradle template of your Unity :

[path to Unity]/PlaybackEngines/AndroidPlayer/Tools/GradleTemplates/mainTemplate.gradle

 

2019.1.3

 

Ok, can you post the contents of your mainTemplate.gradle file ? (please use the "Insert code" button)

thanks that did work your a lifesaver

 

You're welcome : )

I would recommend to put google() before jcenter(), and to use 'com.android.tools.build:gradle:3.2.0'.

Best Regards,

Franck.

Thanks spleendays, you save my life.

 

You are welcome.

 

saved my day! thanks spleendays

 

No problem williambelll

 

This thread was a topmost in google, so I decided to leave a comment.

For those who can't possibly use gradle:3.2.0 and have to use gradle:3.6.0 check out this thread
https://forum.unity.com/threads/bundle-release-launcher-aab-does-not-exist-2019-4-16f1.1025302/

In short, this helped me https://stackoverflow.com/questions...enerated-filename-for-app-bundles-with-gradle

 

Hi, I am working project on Unity version 2020.2.6f1. But when I build AAB for my project, the build gets failed & gets an Error Log.

Here is the Error log :
FileNotFoundException: Temp/gradleOut/launcher/build/outputs/bundle/release/launcher-release.aab does not exist.

Please Help to Resolve this problem.

 

Hello,

Are you using a custom gradle file ? (File > Build Settings > Player Settings > Checkbox named "Custom Gradle Template")

If it's the case, here is a quickfix :

Locate the custom gradle template file (the path is shown below the checkbox), make a backup copy of this file for further analysis / adjustments, and delete it. It will be automatically re-generated by Unity.

Custom gradle template file path :

[PATH TO YOUR UNITY PROJECT]/Assets/Plugins/Android/mainTemplate.gradle


Then, if needed, perform a "Force Resolve" :

Assets > External Dependency Manager > Android Resolver > Force Resolve

This will update the mainTemplate.gradle file contents adequately.


You may also need to make manual adjustments to this file depending on the contents of your backup copy of this file.


A while ago I had this exact same error, that i eventually managed to fix by manually updating the contents of my custom mainTemplate.gradle file, after comparing it with the default gradle template of Unity, located at :

[PATH TO YOUR INSTALL OF UNITY]/PlaybackEngines/AndroidPlayer/Tools/GradleTemplates/mainTemplate.gradle

Best Regards,

Franck

 

None of the above worked for me but I found solution here which suggested to use this code. However, I had to change "launcher-release.aab" with "gradleOut-release.aab" and "launcher.aab" with "gradleOut.aab".

 

Thanks for the feedback.

 

I am using unity 2020.3.14f, I resolved this issue by just removing baseProjectTemplate from my project. Hope it help others as well.

 

Wow I go the Solution!!
Just add the following files in Plugin Folder
https://drive.google.com/drive/folders/1Fbosfmgn4f-bwWgkFAmOZPYjMOrDfsL5?usp=sharing

 

Hello, that folder isn't public :/

 

This post is very suspicious.

 

i got the same issue and i solved it. the above are only gradle files to help others, everyone can understand it.

 

Thanks Adnan, it worked for me
