    This happens on both iOS and Android when using 2018.2.17f1.
    Last successful build was made with 2018.2.16f1.

    Code (CSharp):
    1. #if UNITY_EDITOR && UNITY_CLOUD_BUILD
    2. using System.Collections.Generic;
    3. using System.IO;
    4. using System.Text;
    5. using UnityEditor;
    6. using UnityEngine;
    7.  
    8. public static class PreBuildProcessor
    9. {
    10.     public static void PreprocessBuild(UnityEngine.CloudBuild.BuildManifestObject manifest)
    11.     {
    12.         ...
    13.     }
    14. }
    15. #endif
    I tried to changing PreprocessBuild to PreExport but problem still exist.

    What should I try next?

    Same thing, tried a Linux build:
    26900: [Unity] ERROR: export method 'Derelicts.CloudBuild.PreExportLinux' not found, aborting. Please make sure you are using the correct function signature.


    This used to work with Unity 2017.x (now testing 2018.2.17f1). I also see the following peculiar error in the log, maybe related to this? https://forum.unity.com/threads/clo...ot-find-file-define-unity_cloud_build.586858/

    6250: [Unity] /define:RELEASE

6252: [Unity] /define:UNITY_CLOUD_BUILD

    We are also having this issue. I've temporarily removed the pre-export config but then we're having other issues.

    Seems that the UNITY_CLOUD_BUILD define isn't working correctly. Removing the "#if" temporarily solved the issue for me, running 2018.3.0f2

    Could you check the failed build logs if any of them have the following error message?

    "Assembly 'Library/ScriptAssemblies/Assembly-CSharp-Editor.dll' will not be loaded due to errors"

    Please note that the pre-export method is not detected when Assembly-CSharp-Editor.dll cannot be loaded because any editor scripts placed inside the Assets/Editor folder are compiled into Assembly-CSharp-Editor.dll. So, if this DLL is not loaded, the method inside it is never found.

    If you see this in the logs by any chance, I'd recommend you solve the reference conflicts that are preventing those DLLs from being loaded properly.
