VSCode启动自动运行tasks.json打开终端配置不生效如何解决

问题场景 #

需要实现VSCode打开工作区时自动启动多个指定路径的终端，参考官方实现方案编写.vscode/tasks.json配置后，手动触发任务可以正常生成对应终端，但设置了folderOpen自动运行规则后，启动VSCode打开工作区时任务不会自动执行。
原配置片段如下：

{
  "label": "create terminals",
  "runOptions": { "runOn": "folderOpen", },   // 预期打开文件夹时自动运行，实际未生效
  "dependsOn": [ "foo", "bar" ],
},
{ "label": "foo", "type": "shell", "command": "/bin/zsh", "options": { "cwd": "${workspaceFolder}/foo/", }, "isBackground": true, "problemMatcher": [], "presentation": { "echo": false, "panel": "dedicated", "focus": false, "reveal": "never", "group": "terminals" } },
{ "label": "bar", "type": "shell", "command": "/bin/zsh", "options": { "cwd": "${workspaceFolder}/bar/", }, "isBackground": true, "problemMatcher": [], "presentation": { "echo": false, "panel": "dedicated", "focus": false, "reveal": "never", "group": "terminals" } }

配置预期效果：启动时自动执行create terminals聚合任务，拉起foo、bar两个子任务，分别在工作区下的foo、bar目录启动zsh终端，终端后台运行、不自动抢占焦点、不主动弹出终端面板。

修复步骤 #

• 补全tasks.json的合法结构，原配置片段缺少外层必填的版本号和任务数组包裹，完整可运行的配置如下：

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "create terminals",
      "runOptions": { "runOn": "folderOpen" },
      "dependsOn": ["foo", "bar"]
    },
    {
      "label": "foo",
      "type": "shell",
      "command": "/bin/zsh",
      "options": { "cwd": "${workspaceFolder}/foo/" },
      "isBackground": true,
      "problemMatcher": [],
      "presentation": {
        "echo": false,
        "panel": "dedicated",
        "focus": false,
        "reveal": "never",
        "group": "terminals"
      }
    },
    {
      "label": "bar",
      "type": "shell",
      "command": "/bin/zsh",
      "options": { "cwd": "${workspaceFolder}/bar/" },
      "isBackground": true,
      "problemMatcher": [],
      "presentation": {
        "echo": false,
        "panel": "dedicated",
        "focus": false,
        "reveal": "never",
        "group": "terminals"
      }
    }
  ]
}

• 首次配置完成后，手动执行一次该任务。VSCode会弹出安全确认提示，询问是否允许当前工作区的任务在打开文件夹时自动运行，选择允许即可，后续打开工作区就会自动执行任务拉起对应终端。

如果之前误选了拒绝选项，可打开命令面板执行Tasks: Manage Automatic Tasks in Folder命令，重新为当前工作区开启自动任务权限。

• 若上述操作后仍不生效，检查全局设置：打开VSCode设置页，搜索task.allowAutomaticTasks，确认配置值为on或auto，不要设置为off。
