Bug Build fail due to compiler errors (UWP)

Hello everyone,

I am trying to make a UWP build after the fact that this project can build out to Android without any problems. After switching platform from Android to UWP, all builds fail with this error log. The log does not explain why it failed, instead it just tells me it failed to build due to compiler errors.

I checked the Editor logs, and found nothing useful there to explain why it failed.

Can someone help guide me where or why this build is failing on UWP? I switched the platform to Windows' executable, and it works just fine. I don't know where else I could look into to understand why this fails to build. Building for Android and Windows executable works, only the UWP does not work. I need to create a UWP build for this project (Hard requirement).

Unfortunately, I have no way of simplifying this project down for a bug report, but I can say that I have previously successfully build UWP project before (In a different project that is only for UWP). I am still unclear as to why this would fail on me.

I went as far as to create a empty scene, make that the only scene to build, and still continue to receive the same message as shown in the image below.

I am using Unity 2019.4.31f1 LTS.

Here's my build settings


Here's the error message I received in

 

@Regretful123 Does a new/empty project build to UWP for you, for comparison?

 

Created a new empty game project using the version above with the exact build settings as shown in the picture above, I can export the empty project out.
Still, it bugs me that I cannot find the script that's breaking the build.

Edit: What it sounds like here is that somewhere in the recompiling code, a preprocessor condition was not handled properly... How can I make this exposed/visible?
This is what brought up the preprocessor for a bit -

Code (CSharp):

1. ...
2. [ScriptCompilation] Recompiling all scripts because: Recompiling scripts for player build.
3. BuildPlayer: start building target 21
4. [ScriptCompilation] Recompiling all scripts because: Recompiling scripts for editor because player build failed.
5. DisplayProgressNotification: Build Failed
6. ...

 

Not sure, but you could use the bisection/divide-and-conquer approach (an organized approach to trial-and-error) https://en.wikipedia.org/wiki/Bisection_(software_engineering). This can be time consuming on large projects and not ideal, but is a path forward.

 

I fear for the worst. Going to clone this project and then just start slowly removing plugin/script/scene until the compiler works.

 

I used JeffD's divide and conquer technique. As it turns out, the root cause to prevent the build was coming from one of the plugins "AppCenter". This is no longer a bug with Unity, instead this is a bug with Microsoft's plugin. We were unable to update the plugin, so we ended up having to remove the plugin to get the project exported. Eventually, I'd like to come back to this and understand why the plugin would cause the compile to fail.

 

I've minimized the project down to the barebone to expose the problem.

Please see the case number 1398676 from FogBugz. Let me know if you have any more question.

As to answer to this thread problem, the culprit was that I had two Newtonsoft.Json plugin. One was natively in the Assets/Plugin folder where I need to access. I was unaware that AppCenter also have their own Newtonsoft.json plugin in the AppCenter plugin's folder. The combination of those two plugin exist in the same project was the result of the build failing. However, this doesn't explain why Unity Editor suppresses this message that I needed to see.

I would have expected to see this message.

Thanks @JeffDUnity3D and @Tautvydas-Zilys! Hope to see this patch on the next version!
