我在Visual Studio Code中设置了一个构建代码的任务(类似于如何设置VSCode来编译C++代码？),但正则表达式与g ++的输出不匹配.有什么我做错了吗？这是在MacOS Sierra上.

我有一个名为ItemAssignmentMatrix.cpp的源文件,第15行有一个错误行.

thisisanerror;

我的tasks.json problemmatcher模式regexp看起来像这样:

{
    "version": "0.1.0",
    "command": "make",
    "isShellCommand": true,
    "showOutput": "always",
    "echoCommand": true,
    "suppressTaskName": true,
    "tasks" : [
        {
            "taskName": "clean",
            "args": ["-f" "${workspaceRoot}/Makefile" "clean"]
        },
        {
            "taskName": "build",
            "isBuildCommand": true,
            "args": ["-f" "${workspaceRoot}/Makefile"],
            // Use the standard less compilation problem matcher.
            "problemMatcher": {
                "owner": "cpp",
                "fileLocation": ["relative", "${workspaceRoot}"],
                "pattern": {
                    "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            }
        }
    ]
}

当我执行此任务时,我的Makefile(使用g ++)输出一个错误行,如:

g++ …
