PostExport error: "parameters do not match signature"

    I'm running into an issue when attempting to use the PostExport static function of CloudBuild. The logs show an error on my PostExport static function "parameters do not match signature". I've looked at a number of examples and they use
    Code (CSharp):
    1.  [PostProcessBuild]
    2.     public static void PostExport(BuildTarget buildTarget, string path)
    even though the CloudBuild advanced features documents state that it
    and doesn't mention [PostProcessBuild] or [PostProcessBuildAtrribute]

    I'm clearly not understanding what I'm missing from the equation. Any suggestions?





    Code (CSharp):
    1.  
    2. using UnityEngine;
    3. using UnityEditor;

    16.         string BuildNumber = manifest.GetValue<string>("buildNumber");
    17.         PlayerSettings.bundleVersion = string.Format("{0}.{1}_{2}", PlayerSettings.bundleVersion, BuildNumber, CommitID);

    19.         Debug.Log( string.Format( "New version number <{0}>", PlayerSettings.bundleVersion ) );

    The "Pre and Post" tab of the advanced settings guide mentions the PostProcessBuildAtrribute in the note at the bottom. If you add a method with the PostProcessBuildAtrribute attribute attached to it, that method will automatically be invoked by Unity during the build process without needing to configure the post-export on the Cloud Build advanced settings. If you configure a post-export method in the Cloud Build advanced settings however, it will be invoked AFTER any PostProcessBuildAtrribute methods and has a different signature than the PostProcessBuildAtrribute methods.

    The signature for a PostProcessBuildAtrribute looks like:
    Code (CSharp):
    1. [PostProcessBuildAttribute]
    2. public static void OnPostprocessBuild(BuildTarget target, string pathToBuiltProject);
    The signature for the Cloud Build specific post-export method looks like:
    Code (CSharp):
    1. public static void CloudBuildPostExport(string pathToBuiltProject);

    That's exactly what I thought, but I got the same error when using

    Code (CSharp):
    1. public static void CloudBuildPostExport(string pathToBuiltProject);
    without any [PostProcess] settings,which is why I was so confused.

    I'll try it that way again.

    postExportMethod 'PostprocessBuildPlayer.OnPostprocessBuild'


    public static void OnPostOnPostprocessBuild

    Your names don't match up.

    For future reference (since this has happened to us a few times and we always seem to forget), if something else during your post process throws an exception, then it will be caught at this point and reported as this exception. If you look in the CloudBuild Full Log, somewhere just above this exception should be the real one.
