Problem signing Android build with provided keystore

I'm trying to sign an Android application as part of the Unity Cloud Build process.

These are the steps I've currently completed:

1. Generate a keystore and key using the Unity utility
2. Create Unity Cloud Build configuration, targeting Android
3. Update build Signing Credential configuration to use utilize previously generated keystore and key
4. Trigger clean build

This is the resulting log entry of the error causing the build to fail.

[Unity] ERROR: Execution failed for task ':validateSigningRelease'.
[Unity] ERROR: > Keystore file '/BUILD_PATH/[APP].[BUILD_CONFIG]/Temp/gradleOut/bvr/[GUID].keystore' not found for signing config 'release'.​

I've been trying to locate documentation regarding the signing process, without any luck. Is there any additional steps required to enable signing of Android applications?

 

Solved by downgrading the the Unity Version from Latest 2019.1 BETA to Latest 2018.3

 

Hi. I'm having the some issue with 2019.1 but I would not like to have to downgrade.
Anyone knows of a workaround ?
I tried to include the keystone in the project root but it didn't work.

 

I'm having exact same problem with 2019.1.0f1 version. Local build works fine though..

 

I'm not convinced it's 2019.1 as opposed to something I'm doing wrong.

Does anyone have any diagnostic steps they've developed for this sort of problem?

 

Just on the off chance this really is a bug, I filed one.

 

I'm having the same issue with 2019.1.0f2 cloud builds. Last week it worked fine with 2018.3.

 

Hello,

we're having this same issue with local builds after updating to Unity 2019.1.0f2 (we were on 2018.3.6f1 previously).
Just submitted the bug report, that case number is 1147233

 

Yes. It's 652241. So now you can all see the self-effacing way I engage a product support team.

 

I'll do that in a few hours if nobody else gets to it before me.

Edit: I started one. Do you need me to DM you a link or something?

 

Disabling Cloud Diagnostics didn't help.. Still the same error:
> Keystore file '/BUILD_PATH/[APP-NAME].default-android/Temp/gradleOut/bvr/fee0ead1-be61-4298-b18a-c68fef6ea4d0.keystore' not found for signing config 'release'.

 

I'm going to try disabling all services, now.

 

Here's an interesting ending to that build...

Code (csharp):

I've stripped my build down to the bare minimum I can get away with, at the moment. It didn't help.



Here's a link to the log. I'm assuming there's something secret, in there, or I'd upload it. I'm also assuming unity workers can get past security and see the logs.

@victorw, @Yury-Habets: If you need it sent directly to you, please let me know.

In addition to disabling cloud diagnostics having no effect, I also cannot find that error anywhere in the full logs. In fact, I cannot find the string "TOK" anywhere in there. I'd like to know what the builds that work do to make sure that temporary keystore file is generated...

 

Like, is there an event I can just hook into to copy my .keystore where it needs to be?

 

Another project, that I converted from 2018 to 2019 fails also. The error is related to IAP though:
13: [Unity] Assets/Plugins/UnityPurchasing/script/IAPConfigurationHelper.cs(12,91): error CS0246: The type or namespace name 'ProductCatalog' could not be found (are you missing a using directive or an assembly reference?)
14: [Unity] Assets/Plugins/UnityPurchasing/script/CodelessIAPStoreListener.cs(21,19): error CS0246: The type or namespace name 'ProductCatalog' could not be found (are you missing a using directive or an assembly reference?)

And as always, local builds works fine..

 

I solved that problem. gitignore file was configured incorrectly to not include bin folder.. Anyways, now I got same error than in other project:

> Keystore file '/BUILD_PATH/[APP_NAME].default-android/Temp/gradleOut/bvr/855150c4-6148-4c7b-bd87-d9ff35b067b4.keystore' not found for signing config 'release'.

 

I spent about an hour banging my head against the pre-export event, figuring out that the answer must be "no". I can't seem to find anywhere that tells me where the keystore file is supposed to be, so I can't copy it there. I can't seem to find anywhere that lets me tell the build which keystore to use, so I can't aim the build at where it is.

Anyone else have any ideas?

 

Same problem here, no solution found.

Also noticed that if you configure Unity to use the default debug keystore, and add another keystore in cloud build settings and configure the cloud build target to use that, then the build succeeds, but is signed with the wrong (debug) keystore. This happened after upgrading our project to 2019.1. Previous 2018.x version worked fine.

 

That's an interesting bit of data.

 

Having same issue with with 2019.1.0f2

 

Worked thanks for the quick fix!!

 

It works! Thanks @victorw

 

Yep. Build works. Thanks for fixing it.

 

Was this fix only for Unity Cloud Builds by any chance? In our case Android builds are failing locally, this is still happening with latest version of Unity (as far as I can tell no updates/patches have been made anyway)

 

I never had this issue on local builds. Do you have that exact same error (keystore not found) on local build?

 

Yes - I've just sent them another bug report reproducing the issue in a blank project (case #1150462 ).
You get this error when setting signing assets through script (in a pre-build function, for example) - I'm guessing Unity Cloud builds do the exact same thing under the hood.

Steps to reproduce:
- Create a blank project
- Create a keystore and set it in player settings
- Drop this editor script in the project:

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3. using UnityEditor.Build;
4. using UnityEditor.Build.Reporting;
5.  
6. public class SetKeystore : IPreprocessBuildWithReport
7. {
8.     public int callbackOrder {  get { return 0; } }
9.  
10.     void IPreprocessBuildWithReport.OnPreprocessBuild(BuildReport report)
11.     {
12.         UnityEditor.PlayerSettings.Android.keystoreName = "Path/to/test.keystore";
13.         UnityEditor.PlayerSettings.Android.keystorePass = "123456";
14.         UnityEditor.PlayerSettings.Android.keyaliasName = "test";
15.         UnityEditor.PlayerSettings.Android.keyaliasPass = "123456";
16.     }
17. }
18.  

- Build

the error only happens in 2019.1.0f2 - I've tested with 2018.3.12f1 and it worked fine.

 

How would I enter the absolute path? I can only browse to the keystore via fileselector, and it's then converted to a relative path implicitly.

 

I had to copy the keystore to a place outside the project hierarchy. Then choosing it via fileselector produced a full qualified path and the build ran through fine. Within the hierarchy it was always stripped to a relative path (which usually makes sense, of course)

 

Thanks Habitoti! I had the same problem, all local build, not cloud.

After upgrading to 2019.1.5f1, I got the "keystone file not found" in some Temp directory. I managed to fix this by entering a full path outside the project in Build Settings -> Player Settings -> Project Keystore

 

local build: I run into this don't know if it will work for someone else..
using the same keystore and keystore path: https://ibb.co/SVJmfsJ

i.e one can see in the image attached that Keystore path is already defined, i still redifined it by clicking on browse keystore.

A bit awkward i know...

 

Thanks..!! I solved it !

 

We were using relative paths for our build scripts and solved the problem by using Path.GetFullPath() method.

Code (CSharp):

1. PlayerSettings.Android.keystoreName = relativePath;
2. -->
3. PlayerSettings.Android.keystoreName = Path.GetFullPath(relativePath);

 

It's work

 

Thanks for this info, I've been trying to setup a Jenkins System to automate our builds and had been struggling to figure out why my Android release builds were failing! This thread and the full path to keystore solution got it working on my Unity 2019.1.14f1 setup.

 

I solved this by re-selecting the .keystore file again. After that, the ProjectSettings.asset file changed one line.

from:
AndroidKeystoreName: Assets/Keystore.keystore
To:
AndroidKeystoreName: '{inproject}: Assets/Keystore.keystore'

I guess in Unity 2018 the Project setting writes only the path of the .keystore file. After 2019 it added a '{inproject}: to mark the .keystore file is in the project. In some way or other, my unity updated without modifying the ProjectSettings.asset file which caused this issue.
