Can't build a project that contains ScriptedImporter

Hey guys, I have a problem with Unity and I wasn't able to find any solution.

I have a project that contains ScriptedImporter for my own file format. It all works in the editor but when I want to build actual exe file I get following errors:

Code (csharp):

1. Assets\Plugins\OBLImporter.cs(3,32): error CS0234: The type or namespace name 'AssetImporters' does not exist in the namespace 'UnityEditor.Experimental' (are you missing an assembly reference?)
2. Assets\Plugins\OBLImporter.cs(7,28): error CS0246: The type or namespace name 'ScriptedImporter' could not be found (are you missing a using directive or an assembly reference?)
3. Assets\Plugins\OBLImporter.cs(6,2): error CS0246: The type or namespace name 'ScriptedImporterAttribute' could not be found (are you missing a using directive or an assembly reference?)
4. Assets\Plugins\OBLImporter.cs(6,2): error CS0246: The type or namespace name 'ScriptedImporter' could not be found (are you missing a using directive or an assembly reference?)
5. Assets\Plugins\OBLImporter.cs(9,40): error CS0246: The type or namespace name 'AssetImportContext' could not be found (are you missing a using directive or an assembly reference?)
6. Assets\Plugins\OBLImporter.cs(9,26): error CS0115: 'OBLImporter.OnImportAsset(AssetImportContext)': no suitable method found to override

So how do I solve this problem?

 

remove the experimental in unity 2020


using UnityEditor.AssetImporters;

 

Problem here looks like you have scripts that are making use of UnityEditor namespace that are not in an 'Editor' folder.

 

I'm having this problem, too.

I currently have the scripts listed in my 'Editor' folder in my project assets and when I attempt to build I get the same errors.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using System.IO;
4. using UnityEditor.AssetImporters;
5. using UnityEngine;
6.  
7. [ScriptedImporter(1, "pdf")]
8. public class PDFImporter : ScriptedImporter
9. {
10.     public override void OnImportAsset(AssetImportContext ctx)
11.     {
12.         byte[] bytes = File.ReadAllBytes(ctx.assetPath);
13.         PDFAsset pdfa = new PDFAsset(bytes);
14.  
15.         ctx.AddObjectToAsset("main", pdfa);
16.         ctx.SetMainObject(pdfa);
17.     }
18. }

I had some code attempting to grab PDFs in my Resources folder, but it wouldn't work until I added a custom importer for them. Could have changed the extension, but the goal is to reduce the amount of work when adding new PDFs to the build because there are going to be many of them.

When running the code in Unity it works just fine, but when I go to build it throws these same errors.

Currently running Unity 2021.1.5f1

 

The above script MUST be inside of or under a folder named

Editor

.

Is it?

Yes, they said that, I'm having the same issue.

I fixed this by wrapping the whole file in #if UNITY_EDITOR #endif but this definitely seems like a bug.
