iOS Cloud Build - Fails - No Meaningful Errors and Confusing Stack Trace

We've been working on getting one of our applications building in Cloud Build for best part of a week and we've simply not been able to get a single build working on iOS. There has never been a clear error message in the log whatsoever so we're just trying every permutation with nothing to go on and we've just about run out of things to try now.

Description of issue: The build fails but there are no real errors shown. There's a stack trace with a bunch of Editor related stuff which I *think* is stopping the build but I have no idea how it relates to our project or what we would do to fix it.

Unity version: 5.5.0f3

XCode version: 8

Source control: Git

Local build platform: iOS 10 (via Mac OS Sierra)

Build target: iOS

Relevant plugins being used: Google Play Game Services. A custom plugin to add sqlite3 to the Xcode project. Fabric (with Crashlytics). Keen reporter.

Project name: Iolani Palace App

This is what I consider to be the "relevant chunk" of the build log.

Since there are no real errors, I don't know what the "relevant chunk" of the build log is for sure. So I've uploaded the entire thing here, just in case : https://www.dropbox.com/s/nevf8rl3xcn3f31/CloudBuild.txt?dl=0

It does build locally from a fresh checkout.

 

Hello,

Looking at your project, I can see several compiler errors, for example

To list a few

Are you sure that this builds locally after a fresh check out?
Do you have everything in your project checked into your source control?

Thanks!

The project on CloudBuild is not in the same state it was when I built this and got this error log. One of the other developers has been trying to strip things out of the project to see if they can narrow down what the problem is.

The logs I've reported are accurate for build #14 on Cloud Build.

Yes, I'm quite certain that the project builds locally.

 

Okay, the logs for build #14 show "Abort trap: 6" - this means Unity crashed.

Are you using any PostProcessSceneAttributes? (https://docs.unity3d.com/ScriptReference/Callbacks.PostProcessSceneAttribute.html)

- Sophia

 

We're not using PostProcessSceneAttributes but there is one script which uses [PostProcessBuild] which I guess is the predecessor to it.

EDIT: Removed a false lead.

Code (csharp):

1.  
2. There's this which is my own script we use to set up sqlite3, but we've had the same build problem since long before I added that.
3.  
4. [code]
5. [PostProcessBuild]
6.     public static void OnPostprocessBuild(BuildTarget buildTarget, string path)
7.     {
8.         if (buildTarget == BuildTarget.iOS)
9.         {
10.             string projPath = path + "/Unity-iPhone.xcodeproj/project.pbxproj";
11.  
12.             PBXProject proj = new PBXProject();
13.             proj.ReadFromString(File.ReadAllText(projPath));
14.  
15.             string target = proj.TargetGuidByName("Unity-iPhone");
16.  
17.             proj.AddFileToBuild(target, proj.AddFile("usr/lib/libsqlite3.dylib", "Frameworks/libsqlite3.dylib", PBXSourceTree.Sdk));
18.  
19.             File.WriteAllText(projPath, proj.WriteToString());
20.         }
21.     }
22.  

 

Today I tried removing anything which begins with [PostProcess so that I can get all of the new ones and the old ones. There were a few from Google Analytics and Fabric as well as my own posted above. I rebuilt to see what would happen. Exactly the same result.

So I guess we can conclude that [PostProcess stuff is not the problem.

Any help on this?

 

Bump!
