终端将被任务重用，按任意键关闭。

修改配置文件：tasks.json

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++ build active file",
            "command": "/usr/bin/g++",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },

            "presentation": {
                "echo": true,
                "reveal": "always",
                "focus": false,
                "panel": "new", //这里shared表示共享，改成new之后每个进程创建新的端口
                "showReuseMessage": true,
                "clear": false
            },

            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
    
    }

添加的配置是：

"presentation": {
                "echo": true,
                "reveal": "always",
                "focus": false,
                "panel": "new", //这里shared表示共享，改成new之后每个进程创建新的端口
                "showReuseMessage": true,
                "clear": false
            },
