Build script cannot find "MenuItem"

I tried to do a setup script for my builds. The menu item gets displayed. As soon as I click on the Item, it is fetching some results for my platform but then crashes with errors like:

Code (CSharp):

1. Assets/Scripts/ProjectBuilder.cs(8,6): error CS0246: The type or namespace name `MenuItem' could not be found. Are you missing an assembly reference?
2.  
3. Assets/Scripts/ProjectBuilder.cs(11,9): error CS0246: The type or namespace name `BuildPlayerOptions' could not be found. Are you missing an assembly reference?
4.  
5. Assets/Scripts/ProjectBuilder.cs(12,9): error CS0841: A local variable `buildPlayerOptions' cannot be used before it is declared
6.  
7. Assets/Scripts/ProjectBuilder.cs(14,9): error CS0103: The name `BuildPipeline' does not exist in the current context
8.  

I do not know why it is unable to find those classes after clicking that menu item. I am using Unity 2018.1.2f1 . See below the complete build script. It is basically copied from https://docs.unity3d.com/ScriptReference/BuildPipeline.BuildPlayer.html (Or also https://docs.unity3d.com/Manual/BuildPlayerPipeline.html)

Code (CSharp):

1.  
2. using UnityEditor;
3. using System.Diagnostics;
4. public class ProjectBuilder {
5.     [MenuItem("CustomScripts/Build Android")]
6.     public static void BuildAndroid()
7.     {
8.         BuildPlayerOptions buildPlayerOptions = new BuildPlayerOptions();
9.         buildPlayerOptions.scenes = new[] { "Assets/MainScene.unity" };
10.         buildPlayerOptions.locationPathName = "builds/AndroidBuild";
11.         buildPlayerOptions.target = BuildTarget.Android;
12.         buildPlayerOptions.options = BuildOptions.None;
13.         BuildPipeline.BuildPlayer(buildPlayerOptions);
14.     }
15. }
16.  

Does anyone know what is going wrong? Seems to be a beginners mistake somekind of..

 

That was a beginners question indeed. If you get those errors you have to put the script inside the editor folder. "Assets/Editor/ProjectBuilder.cs" did the trick.

 

Thanks for posting the answer.

 

Thanks for the answer.

 

Wow! Its extremely useful! Thx so much!

 

Thanks!

 

Thanks a lot

 

Thanks a lot

 

Thanks

 

Thank you.

 

BUt i got the same error even i put y script in editor folder

 

were you able to fix this problem.

 

if the same thing happens then click on that error and then automatically a file will be marked in 'Project" TAB and delete that file and build your project again. that worked for me

 

For my project I had to use Assets/Scripts/Editor.
Maybe since I have all scripts in Assets/Scripts.

 

If you want to have it in custom folder you can create a assembly definition in that folder : Create > Assembly Definition
And in the asset properties only select Editor in platforms section.

I found this while creating unit tests.

Thank you all!

 

Thank you very much

 

amazing how the actions of one person can change the lives of so many. Thanks for the solution!

 

That you so much!!!!!!

 

So helpful! Thank you!

 

I faced with build-compile errors where editor-assembly was setup incorrectly.
In case if you have editor-assembly check `Editor` checkbox in `Platforms` section.
