VS 代码自定义问题匹配器不起作用

Question

我在为手表任务设置problemMatcher时遇到问题。regex似乎是正确的，但即使在控制台中显示错误，它也不会在问题选项卡中显示任何错误。我错过了什么？

"problemMatcher": {
"owner": "typescript",
"fileLocation": "autoDetect",
"pattern": [
{
"regexp": "(ERROR|WARNING) in (.+)\(",
"severity": 1,
"file": 2
},
{
"regexp": "^(\d+):(\d+) (.+)$",
"line": 1,
"column": 2,
"message": 3,
"loop": true
}
],
"background": {
"activeOnStart": false,
"beginsPattern": "Type checking in progress\.\.\.",
"endsPattern": "Time: \d+ms"
}
}

终端输出：

> Running compilation in watch mode
> Building component registry...
> Component registry built
> Starting type checking service...
> Type checking in progress...
> Type checking in progress...

从文档

除了问题匹配器上的background属性外，任务本身还必须标记为isBackground，以便任务在后台继续运行。
