Pre-Export Method Failure with no details

I attempted an iOS build using Unity Cloud Build successfully. I then attempted to add in a Pre-Export Method, but it keeps failing with no explanation.

Code (CSharp):

1. 29602: [Unity] ERROR: preExportMethod 'UnityCloudBuild.OnPreExportIOS' failed, aborting.

After reading previous topics related to this, I believe the reason may be because the method can't be found, but I'm not sure why that is. I don't receive any of the Debug logs I manually added, which is another reason I think it can't be found.

My code is as follows:

Code (CSharp):

1.  
2. using UnityEngine;
3. using UnityEditor;
4.  
5. public class UnityCloudBuild : MonoBehaviour
6. {
7.     public static void OnPreExportIOS()
8.     {
9.         Debug.Log("UnityCloudBuild - OnPreExportIOS started");
10.  
11.         FileUtil.DeleteFileOrDirectory("Assets/StreamingAssets/Bundles");
12.         FileUtil.DeleteFileOrDirectory("Assets/StreamingAssets/Bundles.meta");
13.         Debug.Log("UnityCloudBuild - Going to Refresh");
14.         AssetDatabase.Refresh();
15.     }
16. }
17.  
18.  

This is saved within a script in my project, under Assets/Scripts/UnityCloudBuild/UnityCloudBuild.cs

And in the Advanced Options > Pre-Export I enter it as: UnityCloudBuild.OnPreExportIOS

The build has failed after about 2 hours both times, so it's a bit frustrating not knowing why. Any suggestions would be great.

 

Thank you. That was my exact error. Not sure how I missed that when reading through the documentation!

 

The docs also state that you optionally can add a parameter of type "UnityEngine.CloudBuild.BuildManifestObject",
But i cant seem to be able to use that CloudBuild namespace. Any news about this?
On the cloud build page it uses the same example, which is a bit irritating.

 

You need to wrap the whole class in a compiler directive, the BuildManifestObject is only available on the cloud build servers apparently.

For example

#if UNITY_CLOUD_BUILD
using UnityEngine;
using UnityEditor;
using System;

public class CloudBuildHelper : MonoBehaviour
{
public static void PreExport(UnityEngine.CloudBuild.BuildManifestObject manifest)
{
PlayerSettings.bundleVersion = $"1.0.{manifest.GetValue("buildNumber", "unknown")}";
}
}
#endif

 

Hi friends, does that manifest provide the build number specifically listed in the cloud build history? Or is it whatever is set within the project. I would prefer to automatically use the cloud build numbering system.

 

Just going to assume assembly definition files don't work with this. Because that would appear to be the case.

Edit: Actually nevermind, cloud build just randomly failed, building again succeeded

 

Hi friends, I attempted to add Pre-Export method to retrieve the build number from the cloud build. But I keep receiving build failed.

Below are the errors





In both iOS and android
Advanced Options > Pre-Export I enter it as: AutoIncrementVersionCodeInCloudBuild.PreExport

Below are my codes

Code (CSharp):

1.  
2. #if UNITY_CLOUD_BUILD
3. using System;
4. using UnityEngine;
5. using UnityEditor;
6. using System.Collections;
7. using System.Collections.Generic;
8.  
9. public class AutoIncrementVersionCodeInCloudBuild : MonoBehaviour
10. {
11.     public static void PreExport(UnityEngine.CloudBuild.BuildManifestObject manifest)
12.     {
13.         string buildNumber = "";
14.         buildNumber = manifest.GetValue<String>("buildNumber");
15.         Debug.LogWarning("Prebuild launched build number to " + buildNumber);
16.         DebugTool.ClientLog("Setting build number to " + buildNumber);
17.     }
18. }
19. #endif

Any suggestions would be appreciate.

 

Your pre-export function can't be in a class that's derived from a MonoBehaviour. If you remove the MonoBehaviour part it should work ok.

 

Thanks for the advice, I also remove the DebugTool.ClientLog, and the build can work fine without having any errors
