MSBuild执行任务无阻塞 [英] MSBuild exec task without blocking

问题描述

有人会碰巧知道一种可以阻止该MSBuild任务的把戏吗?我真的只想打开资源管理器并继续构建脚本.目前，它在执行任务时处于阻塞状态，直到关闭浏览器窗口.

Would anyone happen to know a trick that will keep this MSBuild task from blocking? I really just want the explorer to open and the build script to keep on going. Currently it blocks at the Exec task until the explorer window is closed.

<Target Name="OpenExplorer">
    <Exec Command='explorer.exe "$(DestinationDir)"' IgnoreExitCode="true" />
</Target>

谢谢！

编辑:我希望避免为此创建自定义任务.也许存在一些命令行魔术可以放在Command的行内?

I was hoping to avoid creating a custom task for this. Perhaps some command line magic exists that could be placed inline for the Command?

推荐答案

您不能使用本机Exec来做到这一点.但是您可以编写自己的异步触发代码，例如 此示例 :

You can't do it with the native Exec. But you can write your own that fires asynchronously, as in this example:

  public class AsyncExec : Exec {
    protected override int ExecuteTool(string pathToTool,
                                       string responseFileCommands,
                                       string commandLineCommands) {
      Process process = new Process();
      process.StartInfo = GetProcessStartInfo(pathToTool, commandLineCommands);
      process.Start();
      return 0;
    }

    protected virtual ProcessStartInfo GetProcessStartInfo(string executable,
                                                           string arguments) {
      if (arguments.Length > 0x7d00) {
        this.Log.LogWarningWithCodeFromResources("ToolTask.CommandTooLong", new object[] { base.GetType().Name });
      }
      ProcessStartInfo startInfo = new ProcessStartInfo(executable, arguments);
      startInfo.WindowStyle = ProcessWindowStyle.Hidden;
      startInfo.CreateNoWindow = true;
      startInfo.UseShellExecute = true;
      string workingDirectory = this.GetWorkingDirectory();
      if (workingDirectory != null) {
        startInfo.WorkingDirectory = workingDirectory;
      }
      StringDictionary environmentOverride = this.EnvironmentOverride;
      if (environmentOverride != null) {
        foreach (DictionaryEntry entry in environmentOverride) {
          startInfo.EnvironmentVariables.Remove(entry.Key.ToString());
          startInfo.EnvironmentVariables.Add(entry.Key.ToString(), entry.Value.ToString());
        }
      }
      return startInfo;
    }
  }

随后可以运行:

<AsyncExec Command="..." />
