如何使vscode不等待完成preLaunchTask?

Mike Lischke:

我在Visual Studio代码中有一个调试设置,在其中运行一个外部二进制文件,该文件可以执行我的JS文件(使用duktape)。调试适配器当前仅支持附加请求(不启动),因此我必须先运行二进制文件,然后才能调试JS脚本。

为了避免必须手动启动该应用程序,我为其创建了一个任务,并将其设置在launch.json文件中:

{
    "version": "0.2.0",
    "configurations": [{
        "name": "Attach MGA",
        "type": "duk",
        "preLaunchTask": "debug mga",
        "request": "attach",

        "address": "localhost",
        "port": 9091,

        "localRoot": "${workspaceRoot}",

        "stopOnEntry": false,
        "debugLog": true
    }]
}

任务的定义如下:

{
    "version": "0.1.0",
    "command": "<absolute path to>/mga",
    "isShellCommand": false,
    "showOutput": "always",
    "suppressTaskName": true,
    "tasks": [{
        "taskName": "debug mga",
        "args": ["--debugger", "main.json"]
    }]
}

现在的问题是,vscode等待预启动任务完成,而应用程序则等待调试器附加。赶上22。

如何避免vscode等待启动前任务完成?

更新

同时,我已经阅读了vscode任务页面,并提出了此任务配置。不过,这对我不起作用

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "launch-mga",
            "type": "shell",
            "command": "<absolute path to>/mga",
            "args": [
                "config/main.json",
                "--debugger"
            ],
            "isBackground": true,
            "problemMatcher": {
                "owner": "custom",
                "pattern": {
                    "regexp": "_____"
                },
                "background": {
                    "activeOnStart": true,
                    "beginsPattern": "^.*Waiting for debug connection.*$",
                    "endsPattern": "^.*blah.*$"
                },
            },
        }
    ]
}

启动的应用程序将打印等待消息,然后无限期地等待调试连接。也许问题与使用C ++编写的应用程序(有点像终端应用程序那样的Node.js)有关?

这对我有用。

请注意,所有这些都是必需的,即使它们都不重要:

  • problemMatcher.pattern.regexp
  • problemMatcher.pattern.file
  • problemMatcher.pattern.location
  • problemMatcher.pattern.message
  • problemMatcher.background.activeOnStart
  • problemMatcher.background.beginsPattern
  • problemMatcher.background.endsPattern
{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "label": "build-extras",
      "type": "shell",
      "isBackground": true,
      "command": "./script/build-extras",

      // This task is run before some debug tasks.
      // Problem is, it's a watch script, and since it never exits, VSCode
      // complains. All this is needed so VSCode just lets it run.
      "problemMatcher": [
        {
          "pattern": [
            {
              "regexp": ".",
              "file": 1,
              "location": 2,
              "message": 3
            }
          ],
          "background": {
            "activeOnStart": true,
            "beginsPattern": ".",
            "endsPattern": ".",
          }
        }
      ]
    }
  ]
}
