从C＃运行build.ps1时获取Cake脚本输出

Question

使用Powershell引导程序（build.ps1）运行Cake脚本时，会获得一些详细的控制台输出，您可以使用-Verbosity选项对其进行进一步配置。

但是，当我从可执行文件（基本上是我们自己的CLI）中运行脚本时，尽管已订阅了所有Powershell数据流，但我并未从cake上获得控制台输出。

有没有办法解决这个问题？

用于执行和获取脚本事件的Powershell代码：

public class PowerShellCommandService: IPowerShellCommandService
{
    public void ExecutePowershellScript(string script)
    {
        Console.WriteLine($@"Executing script: {script}");
        using (var localRunspacePool = RunspaceFactory.CreateRunspacePool())
        {
            localRunspacePool.Open();

            using (var engine = System.Management.Automation.PowerShell.Create())
            {
                engine.RunspacePool = localRunspacePool;
                engine.AddScript(script);
                engine.Streams.Debug.DataAdded += Debug_DataAdded;
                engine.Streams.Information.DataAdded += Information_DataAdded;
                engine.Streams.Error.DataAdded += Error_DataAdded;
                engine.Streams.Verbose.DataAdded += Verbose_DataAdded;
                var asyncResult = engine.BeginInvoke();

                Console.WriteLine("Starting script from CLI... ");
                var stopwatch = Stopwatch.StartNew();
                while (!asyncResult.IsCompleted && stopwatch.ElapsedMilliseconds < 240000)
                {
                    Thread.Sleep(500);
                }
                stopwatch.Stop();
                if (stopwatch.Elapsed.TotalSeconds > 240)
                {
                    Console.WriteLine($"Script timed out after {stopwatch.Elapsed.TotalSeconds}s. Asking Powershell to stop.");                        
                    engine.Stop();
                    Console.WriteLine("Stopped. Script execution aborted..");
                    //engine.BeginStop((test) => Console.WriteLine("Stopped."), state);
                }
                else
                {
                    Console.WriteLine($"Script completed in {stopwatch.Elapsed.TotalSeconds}s.");
                }
            }
        }
    }

    private void Verbose_DataAdded(object sender, DataAddedEventArgs e)
    {
        if (sender is PSDataCollection<VerboseRecord>)
        {
            var collection = sender as PSDataCollection<VerboseRecord>;
            Console.WriteLine(collection[e.Index]);
        }
    }

    private void Debug_DataAdded(object sender, DataAddedEventArgs e)
    {
        if (sender is PSDataCollection<DebugRecord>)
        {
            var collection = sender as PSDataCollection<DebugRecord>;
            Console.WriteLine(collection[e.Index]);
        }
    }

    private void Error_DataAdded(object sender, DataAddedEventArgs e)
    {
        if (sender is PSDataCollection<ErrorRecord>)
        {
            var collection = sender as PSDataCollection<ErrorRecord>;
            Console.WriteLine(collection[e.Index]);
        }
    }

    private void Information_DataAdded(object sender, DataAddedEventArgs e)
    {
        if (sender is PSDataCollection<InformationRecord>)
        {
            var collection = sender as PSDataCollection<InformationRecord>;
            Console.WriteLine(collection[e.Index]);
        }
    }
