Run a specific launch from task in vscode

Solution 1:

You can use the extension Launch Configs

In the extension settings (settings.json) you setup a command to start a launch config

"launches": {
    "StartLaunch": "Start Launch (Project Folder)"
}

In you tasks.json call this task with a variable ${command:commandID} somewhere in the task strings.

${command:launches.StartLaunch}

You can use a dummy shell echo task
