Task.json "Matches multiple schemas when only one must validate."

[roa-nyx]

Issue Type: Bug

I am creating tasks.json entries similar to https://github.com/...

My final tasks.json is:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "watch-app",
            "dependsOn": [
                "watch-app-cs",
                "watch-app-js"
            ],
            "problemMatcher": []
        },
        {
            "label": "watch-app-cs",
            "type": "shell",
            "options": {
                "cwd": "./App"
            },
            "command": "dotnet",
            "args": [
                "watch",
                "run"
            ],
            "presentation": {
                "group": "watch-app"
            }
        },
        {
            "label": "watch-app-js",
            "type": "shell",
            "options": {
                "cwd": "./App"
            },
            "command": "npm",
            "args": [
                "run",
                "watch"
            ],
            "presentation": {
                "group": "watch-app"
            }
        }
    ]
}

And it appears to work, however when I have the tasks.json file open the { above "label": "watch-app" has a green squiggly underline and hovering over it gives me "Matches multiple schemas when only one must validate."

Am I doing something wrong? Or should this actually be treated as valid?

Just updated to 1.31.0 and getting this too. Error occurs for the 3rd task for me:

{
    "label": "label-name",
    "dependsOn": "npm: start", "npm: "dev-server"],
}

If I add a "type" prop the error seems to go away. Is "type" is required now? If so what should it be set to for compound tasks? I tried both "shell" and "process" and neither worked.

I was referenced this doc when creating my tasks.json: https://code.visualstudio.com/docs/editor/tasks#_compound-tasks

First i add "presentation.group" in existing tasks.json, before work perfectly. I tried and understood that I didn't need it, deleted these lines and the launch attempt led to a similar error. I am nothing change in tasks.json and restart vscode. Fixed. Magic.

Thank you for filing this!

[alexr00]

I tested out several configurations, but the task schema is complex and I may have missed something. Let me know if this solves your cases!

[roa-nyx]

Apologies @alexr00 I'm confused by your last comment. Has this fix been released so I can test it? Is this task currently in a state that you need feedback, or is it closed/will be fixed in next release? I haven't seen any update come through on VSCode (still on 1.31.0).

[alexr00]

The fix is in the VS Code Insiders build. You can try it out there now, or you can wait for the February release. If you do try out the Insiders build it would be great if you could confirm that the validation error is gone since it will give me a chance to make further fixes before the February release if needed 😊

[roa-nyx]

Ok, sweet. I'll maybe try that later today if I can get the insiders build to install SxS with the stable release.

I have the same problem with the Production version. I've loaded up my project in VSCode Insiders and it appears to be working. I don't have the warning in my Tasks.json on the Insiders build.

I've just updated to 1.32.1 production build and still getting the warnings. Is that to be expected? I've included a copy of my tasks.json file in case it helps you.

I'm getting this issue also, and in addition changes I make to tasks.json aren't reflected in the list of tasks presented on the debug window - I have to restart vscode in order to be able to run new tasks.

@david-waterworth, can you open a new issue with your repro steps? @noppej, you shouldn't still be getting the Matches multiple schemas warning. Thanks for providing the tasks.json. I will take a look.

[noppej]

@alexr00 ... Thank you. I am traveling today, but if you need more info, let me know and I will forward asap.

[alexr00]

@noppej, I tested with your tasks.json, and I don't see any warnings. I'm wondering if you have an extension installed that is also providing a schema for tasks.json? Can you try disabling all your extensions then reloading?

[noppej]

Hi @alexr00 ... you called it :) I disabled (with reload) my extensions one by one, and the culprit appears to be the C/C++ extension from Microsoft. When I disabled it, the warning goes away. Then re-enabling it, brings the warning back. Any suggestions on how I can pursue this further?

[alexr00]

I can see why it's happening with that extension. It contributes a task definition that conflicts with the default task definition: https://github.com/Microsoft/vscode-cpptools/blob/master/Extension/package.json#L46 I will follow up with them to understand why that exists.

Hi Alex, I've just installed a fresh vcode 1.32.3 on ubuntu LT16. I have no vcode extension at all. I use a single compilation task in my tasks.json and I've got this issue too. Thanks for helping me in working around with this issue. Cheers ! Sylvain

Below my tasks.json :

{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "label": "build gdk1", // Make this the default build command. "group": { "kind": "build", "isDefault": true }, // Show the output window only if unrecognized errors occur. "presentation": { "echo": true, "reveal": "always", "focus": false, "panel": "shared" }, "command":[
"make"
] , // No args "args": [ "clean", "all" ], // Use the standard less compilation problem matcher. "problemMatcher": { "owner": "cpp", "fileLocation": [ "relative", "${workspaceRoot}" ], "pattern": { "regexp": "^(.):(\d+):(\d+):\s+(warning|error):\s+(.)$", "file": 1, "line": 2, "column": 3, "severity": 4, "message": 5 } } } ] }

[alexr00]

@vynilas I can reproduce. Thanks for sharing your tasks.json.

[vynilas]

Thanks for your feedback. BTW, FYI, there's only a warning, but the task is not performed at all. Cheers !

[vynilas]

Moreover, this tasks.json works flawlessly on vcode v1.32.1 , Electron 3.1.3

[alexr00]

I checked on v 1.32.1 and it has the same warning with your tasks.json.

Weird !! (See below) This vcode instance embeds C/C++ MS intellisense 0.21.0 and austin C++ intelissense v0.22
