[MenuItem("bat/merge")]
public static void merge(){
    Process p = GetNewProcess("git_merge.bat")
    p.Exited =(obj,e)=>{
        if(p.ExitCode == -1) return;
        Debug.Log(p.ExitCode);
        ...
        // following code would not run
        Debug.Log(PlayerSettings.bundleVersion);
        if(Application.isPlaying)...
    }
    p.Start();
}

There is no exception being thrown. It seems like if I try to get some Editor-related value, the process will be terminated.

CodePudding user response：

Most of Unity API is only accessible from the Unity main thread.

The event p.Exited is most likely not invoked on that thread but async.

=> You will need to have a "Main thread dispatcher" running in the Unity main thread and awaiting your result

Usually you do this on runtime using a MonoBehaviour but in this case here it is an editor script so you could e.g. go for

[MenuItem("bat/merge")]
public static void merge()
{
    Process p = GetNewProcess("git_merge.bat");
    p.Exited  = (obj, e) =>
    {
        // Instead of directly executing your code you instead 
        // move it into a callback function
        void MainThreadCallback()
        {
            // Since you want to execute this only once remove the callback
            EditorApplication.update -= MainThreadCallback;

            // I would put this first just for debugging reasons ;)
            Debug.Log(p.ExitCode);
            if (p.ExitCode == -1) return;

            Debug.Log(PlayerSettings.bundleVersion);

            if (Application.isPlaying)
            {
                //...
            }
        }

        // Then you tell the editor to call your callback 
        // with the next global editor update
        EditorApplication.update  = MainThreadCallback;
    };
    p.Start();
}
