json - 我可以在 vs 代码中为一种以上的语言配置 task.json 文件吗？

Question

我想在 VS Code 中配置一个 tasks.json 文件来运行 python 和 java 代码只需按下:

Ctrl + Shift + B

Python 和 Java 已配置，但需要两个不同的 tasks.json 文件。
但我只能在 tasks.json 文件夹中保留一个 .vscode 文件。
如何在 tasks.json 文件中合并两个配置文件？
对于 Python:

{
  "version": "2.0.0",
  "tasks": [{
    "label": "Compile and run",
    "type": "shell",
    "command": "",
    "args": [
      "/usr/bin/time",
      "-v",
      "--output",
      "sys.txt",
      "timeout",
      "5",
      "python3",
      "${relativeFile}",
      "<",
      "input.txt",
      ">",
      "output.txt",
    ],
    "group": {
      "kind": "build",
      "isDefault": true
    },
    "problemMatcher": {
      "owner": "py",
      "fileLocation": [
        "relative",
        "${workspaceRoot}"
      ],
      "pattern": {
        "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
        "file": 1,
        "line": 2,
        "column": 3,
        "severity": 4,
        "message": 5
      }
    }
  }],


}

对于 Java:

{
  "version": "2.0.0",
  "tasks": [{
    "label": "Compile and run",
    "type": "shell",
    "command": "",
    "args": [
      "/usr/bin/time",
      "-v",
      "--output",
      "sys.txt",
      "timeout",
      "5",
      "java",
      "${relativeFile}",
      "<",
      "input.txt",
      ">",
      "output.txt",
    ],
    "group": {
      "kind": "build",
      "isDefault": true
    },
    "problemMatcher": {
      "owner": "java",
      "fileLocation": [
        "relative",
        "${workspaceRoot}"
      ],
      "pattern": {
        "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
        "file": 1,
        "line": 2,
        "column": 3,
        "severity": 4,
        "message": 5
      }
    }
  }],
}

很简单，您只需合并 "tasks":[] 数组并唯一地命名您的任务。任务数组可以包含任意数量的任务对象，有些也可以相互依赖。 More info on VSCode Tasks
在这里，当您使用 this 和 CTRL + SHIFT + B 时，它​​将显示选择任务的选项。

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Compile and run Python",
            "type": "shell",
            "command": "",
            "args": [
                "/usr/bin/time",
                "-v",
                "--output",
                "sys.txt",
                "timeout",
                "5",
                "python3",
                "${relativeFile}",
                "<",
                "input.txt",
                ">",
                "output.txt"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "problemMatcher": {
                "owner": "py",
                "fileLocation": ["relative", "${workspaceRoot}"],
                "pattern": {
                    "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            }
        },
        {
            "label": "Compile and run Java",
            "type": "shell",
            "command": "",
            "args": [
                "/usr/bin/time",
                "-v",
                "--output",
                "sys.txt",
                "timeout",
                "5",
                "java",
                "${relativeFile}",
                "<",
                "input.txt",
                ">",
                "output.txt"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "problemMatcher": {
                "owner": "java",
                "fileLocation": ["relative", "${workspaceRoot}"],
                "pattern": {
                    "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            }
        }
    ]
}

由于无法根据文件扩展名 ( See Issue here ) 告诉 VSCode 运行哪个任务。
您始终可以为构建任务创建键盘快捷键并执行它，而无需从弹出窗口中选择它。例如，对于下面的 tasks.json，您可以通过将其添加到 keybindings.json 文件来创建快捷方式。

[{
  "key": "ctrl+alt+h",
  "command": "workbench.action.tasks.runTask",
  "args": "Compile and run Python" // this text should match exactly with task "label"
}]
