VSCode problemMatcher $gcc 似乎不见了

The VSCode problemMatcher $gcc seems to be gone

我的任务配置为使用 $gcc problemMatcher。这曾经工作正常,但现在 vscode 抱怨:

{
    "resource": "/home/src/example/.vscode/tasks.json",
    "owner": "_generated_diagnostic_collection_name_#0",
    "code": "1",
    "severity": 4,
    "message": "Value is not accepted. Valid values: \"$msCompile\", \"$lessCompile\", \"$gulp-tsc\", \"$jshint\", \"$jshint-stylish\", \"$eslint-compact\", \"$eslint-stylish\", \"$go\", \"$lessc\", \"$node-sass\", \"$tsc\", \"$tsc-watch\".",
    "startLineNumber": 11,
    "startColumn": 31,
    "endLineNumber": 11,
    "endColumn": 37
} 

如您所见,$gcc 不在有效值列表中。怎么会?

这是我的 VSCode 版本:

我在启用 ms-code.cpptools 时注意到同样的错误,它消失了。
