无法在 VS Code 中多次使用预启动任务

Question

我试图多次使用预启动任务来执行我的 launch.json 文件中的两个不同任务。不幸的是，它只执行我的 launch.json 文件中的最后一个预启动任务。我的 tasks.json 中的任务使用相同的命令（"g++"）来编译我的程序，但它们的参数不同（那是因为我需要先将我的源代码编译成 "O"文件，然后将 "O" 文件编译成 "exe" 文件），所以我正在寻找一种方法，如何仅使用一个预启动任务在 launch.json 文件中执行这两个任务.还有其他想法吗？

tasks.json:

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "0.1.0",
    "tasks": [
        {
            "taskName": "CompileToOfile",
            "command": "g++",
            "args": [
                "-c","${fileBasename}",
                "-o","${fileBasenameNoExtension}.o",
                "-I","/Users/Acer/MinGW64/include",

            ],
            "isShellCommand": true
        },
        {
            "taskName": "CompileWGDBWBGI",
            "command": "g++",
            "args": [
                "${fileBasenameNoExtension}.o",
                "-o",
                "${fileBasenameNoExtension}.exe",
                "-L","/Users/Acer/MinGW64/lib32",
                "-L","Users/Acer/MinGW64/x86_64-w64-mingw32/lib32",

                "-lole32",
                "-m32"
            ],
            "isShellCommand": true
        }
    ]
}

launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(Windows) Launch",

        },

                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

Answer 1

您只能有一个 preLaunchTask，但您可以将 "dependsOn": "CompileToOfile" 添加到您的 CompileWGDBWBGI 任务中，然后将其用作您的 preLaunchTask。这样，在每次执行 CompileWGDBWBGI.

之前执行 CompileToOfile
