The pre- and post-export methods let you trigger actions before and after your Unity Project is built. These methods must exist as code in your Project in the Assets/Editor folder. If the Editor folder doesn’t exist in your directory, create it.
Important: The UnityEngine.CloudBuild.BuildManifestObject class is only available when running in Cloud Build (as in, not locally). To compile your code locally, wrap your pre- and post-export methods in an
#if UNITY_CLOUD_BUILD block.
You set pre- and post-export methods in the build target’s Advanced Options.
To use a pre-export method, create a public static method in your Unity Project that contains the code you want executed before the Unity Editor exports your Project.
public static void PreExport()
通过将 BuildManifestObject 对象指定为方法签名中的参数，即可使 Cloud Build 将当前编译的编译清单传递到导出前方法。随后可以在导出项目之前更改项目设置或 Player 设置。
public static void PreExport(UnityEngine.CloudBuild.BuildManifestObject manifest)
Unity Cloud Build 调用该方法时，它会将 BuildManifestObject 对象作为可选参数传递（其中的 BuildManifestObject 是当前编译的编译清单）。
有关更多信息，请参阅 ScriptableObject 格式的编译清单。
To use the post-export method, create a public static method in your Unity Project that contains the code you want executed after the Unity Editor exports your Project.
public static void PostExport(string exportPath)
Unity Cloud Build 调用该方法时，它将传递字符串：
Note: If you’ve tagged any methods in your code with the Unity PostProcessBuildAttribute, those methods are executed before any methods configured as post-export methods in Unity Cloud Build.
