vscode自定义任务问题匹配器找不到与regex匹配的文本

Question

下面是我在.vscode目录中的整个tasks.json文件

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",

                    }
                },
                {
                    "owner": "ld65-c",
                    "fileLocation": "autoDetect",
                    "pattern": {
                        "regexp": "^ld65:\\s+(warning|error|Warning|Error): (\\d+.*)$",

                {

                    "fileLocation": [
                        "relative",

                        "regexp": "^(.*)\\((\\d.*)\\):\\s+(warning|error|Warning|Error):\\s+(.*)$",
                        "file": 1,
                        "line": 2,
                        "severity": 3,
                        "message": 4
                    }
                }
            ]
        },
        {
            "label": "clean",
            "type": "shell",
            "command": "make",
            "args": [
                "clean"
            ],
            "group": "build",
            "presentation": {
                "reveal": "always",
                "echo": true,
                "showReuseMessage": false,
                "clear": true
            }
        }
    ]
}

下面是我正在处理的文本输出的结尾：

cl65 -C src/cmn-src-atarixl-xex.cfg --start-addr 0x4000 -Ln build/bin/cfgame.lbl --ld-args --dbgfile,build/bin/cfgame.dbg --mapfile build/bin/cfgame.map -o build/bin/cfgame.xex build/cf_fileUtils.o build/cf_font.o build/cf_mapEditor.o build/cf_pixmapViewer.o build/cf_tileMap.o build/cf_types.o build/cf_utils.o build/gr7utils.o build/gr12utils.o build/main.o build/pmg.o build/splash.o C:/cc65/lib/atarixl.lib

检测到的问题出现得更早，但它也找到了找到的2个未解析的外部文本。但是，它在输出中找不到与未解析的外部文本相关的特定信息。我在相同的输出上使用regex101.com测试了我的regex。我已经尝试了一些变体-主要是在定义问题匹配器的json中的一些差异。

目标是将未解决的外部项作为引用实际符号名称的单个问题列出。

我已经阅读了其他相关的帖子和答案，并尝试了不同的方法，因此"owner“参数被设置为字符串'ld65-a‘等。

我还尝试更改了定义问题匹配器的顺序，将未解析的外部匹配器移到数组中的第一项-这似乎并不重要。

我意识到还有其他方法来运行make任务，但我需要与gnu make集成，这似乎是一种合理的方法。也许在这方面有一个更好的想法--例如，在我的vscode工作区上运行gnu make。

Unresolved匹配器是一个多行问题匹配器

        {
          "owner": "ld65-a",
          "fileLocation": ["relative", "${workspaceFolder}"
          ],
          "severity": "error",
          "pattern": [
            {
              "regexp": "^(Unresolved external)\\s+'([^']+)'.*:$",
              "message": 1,
              "code": 2
            },
            {
              "regexp": "^\\s+(.*)\\((\\d+)\\)$",
              "file": 1,
              "line": 2
            }
          ]
        },
