How to cause build to fail

I am trying to cause the build to fail with an editor script when it detects a prefab in the scene. I have the prefab detection working fine but I am unable to figure out how to actually get the build to fail.

Debug.LogError() gets an error in the console output, build still successful.

Throwing a BuildFailedException gets an error in the console output, build still successful.

I want the build to fail and stop right when my editor script detects the prefab. I'm using IProcessScene and OnProcessScene() as the method of prefab detection.

How do you get the build to fail?

 

Try Debug.LogException. I'm not sure, but usually it prevents to enter to play mode.
Although it may be not possible. https://feedback.unity3d.com/sugges...tprocessbuild-buildpipeline-dot-cancelbuild-1

 

Build still continues and completes reporting "succeeded".

 

I just wonder, since you know you got error, why you are building project? It is manual process anyway. Or you have some automation in place?

 

I am creating an editor script that detects a specific condition and will cause the build to fail as a result.

 

Bump. I found a way to do it but there's a problem. The error appears not just while building but compiling.

I used OnValidate() function:

Code (CSharp):

1. bool debug;
2.  
3. private void OnValidate()
4.     {
5.         if (debug)
6.         {
7.             Debug.LogError("Build failed because one of your CharacterSpawner is in debug mode! " +
8.                 "Scene: " + SceneManager.GetActiveScene().name + " GameObject: " + gameObject.name);
9.         }
10.     }

It forces build to fail but the error occurs at other times as well. How can I make it only happen while building?
