Jenkins Unity build exits without and log output

Question

I'm trying to setup Jenkins to build my Unity project but am running into some problems. The editor command line is called successfully but then waits for about 1min30sec and exits with a code of 1. I'm sure that the environment variable is real since I use it to call the editor in the first place. To get more info about the issue I tried running all the commands manually but alas, nothing.

The unity install folder is in the path.
I am not using the unity3d-builder plugin.

The log is as follows:

 ...
 [Pipeline] withEnv
 [Pipeline] {
 [Pipeline] stage
 [Pipeline] { (Build Windows)
 [Pipeline] bat
 [rojectBright_game-CGUF3OHWBZNNV2VWAACJWLXACIDF7UD33WABSV4VPGISISZS6HYA] Running batch script

 [Pipeline] // withEnv
 [Pipeline] }
 [Pipeline] // node
 [Pipeline] End of Pipeline
 
 GitHub has been notified of this commit’s build result
 
 ERROR: script returned exit code 1
 Finished: FAILURE

And the Jenkinsfile is:

 pipeline {
   agent any
   stages {
     stage('Build Windows') {
       steps {
         bat 'Unity.exe -batchmode -executeMethod BOCBuild.BuildWindows -projectPath "%WORKSPACE%" -logfile'
       }
     }
     stage('Archive Windows') {
       steps {
         archiveArtifacts 'Build\\BOC-Windows*'
       }
     }
   }
 }

And the BOCBuild class is:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEditor;
 
 public class BOCBuild {
     public static void BuildWindows () {
         System.Console.WriteLine("Beginning Windows Build");
         string path = System.Environment.GetEnvironmentVariable("WORKSPACE");
         if (path == null) EditorApplication.Exit(1);
         BuildPipeline.BuildPlayer(EditorBuildSettings.scenes, path + @"\Build\BOC-Windows.exe", BuildTarget.StandaloneWindows64, BuildOptions.None);
         EditorApplication.Exit(0);
     }
 }

Thanks for your help.

With Jenkins you should use the available Unity plugin:

https://wiki.jenkins.io/display/JENKINS/Unity3dBuilder+Plugin

source code:

https://github.com/jenkinsci/unity3d-plugin

Or, alternately, pipe the file C:\Users\\AppData\Local\Unity\Editor\Editor.log to Jenkins, since that's where Unity writes its output.

I cannot use the unity3d-builder as it does not work with the most recent version of jenkins and has not been updated in 2 years. I am looking for a pure jenkins only solution if possible.

With the current -logfile argument, Unity is supposed to pipe its output to stdout. There is no localappdata unity editor folder.

Then it's likely caused by your command lacking the "-quit" argument.

Remember to add "-nographics" if you run Jenkins as a headless user (i.e: macOS or limited windows user).

Also, it's possible Unity might pipe some messages to stderr as well so add "2>&1" just to be sure.

Final command would be:

 "Unity.exe -quit -batchmode -nographics -execute$$anonymous$$ethod BOCBuild.BuildWindows -projectPath "%WOR$$anonymous$$SPACE%" -logfile 2>&1"

EDIT: You should crash if the build fails. $$anonymous$$aybe even print the error.

 string error = BuildPipeline.BuildPlayer(EditorBuildSettings.scenes, path + @"\Build\BOC-Windows.exe", BuildTarget.StandaloneWindows64, BuildOptions.None);
 if( string.IsNullOrEmpty( error ) )
     EditorApplication.Exit( 0 );
 else
     EditorApplication.Exit( 1 );

Damn this comment editor sucks.
