Using command variables in task with CMake Tools

Brief Issue Summary

Tried to use this in tasks.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "CMake Build",
            "command": "${command:cmake.build}",
            "type": "shell",
            "group": "build",
            "problemMatcher": []
        }
    ]
}

Or

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "CMake Build All",
            "command": "${command:cmake.buildAll}",
            "type": "shell",
            "group": "build",
            "problemMatcher": []
        }
    ]
}

Expected:

CMake Tools to build project as when running “CMake: Build” or “CMake: BuildAll” command from command palette.

Apparent Behavior:

Got error: For “CMake Build”:

[rollbar] Unhandled exception: Unhandled Promise rejection: build TypeError: Cannot read property 'fsPath' of undefined {}

For “CMake Build All”:

[rollbar] Unhandled exception: Unhandled Promise rejection: buildAll TypeError: str.replace is not a function {}

After “CMake Build All” task CMake tools becomes broken, and even from CMake side panel gives an error:

A CMake task is already running. Stop it before trying to build.

I think the example at the beginning of the issue (which you used) is the old way of attempting to do this. Try to apply the below changes to your example and let us know how that works: “command”: “build”, “type”: “cmake”,

Also, if(or when) command variable feature becomes working, it would be nice to publish the command IDs for CMake Tools somewhere in documentation. Because I wasn’t able to find it anywhere except CMake Tools’s sources.
