The task provider for "C/C++" tasks unexpectedly provided a task of type "shell".

[sarahkittyy]

VSCode version:

1.45.0-insider
a0fe37870c42e0704a492cdc6b8550b4cf23f63c
x64

vscode-cpptools version: 0.28.0-insiders

Here is my tasks.json.

{
	"version": "2.0.0",
	"tasks": [
		{
			"label": "gen",
			"type": "shell",
			"command": "cmake",
			"args": [
				"-DCMAKE_BUILD_TYPE=DEBUG",
				".."
			],
			"options": {
				"cwd": "build"
			}
		},
		{
			"label": "make",
			"type": "shell",
			"command": "make",
			"args": [
				
			],
			"group": {
				"kind": "test",
				"isDefault": true
			},
			"dependsOn": "gen",
			"options": {
				"cwd": "build"
			}
		},
		{
			"label": "run",
			"type": "shell",
			"command": "./build/infidungeon",
			"args": [
				
			],
			"group": {
				"kind": "build",
				"isDefault": true
			},
			"dependsOn": "make"
		}
	]
}

If I change my code, or otherwise sometimes completely randomly, when I run task run, I get this message:

And when I hit, "Show output" I see:

The task provider for "C/C++" tasks unexpectedly provided a task of type "shell".
The task provider for "C/C++" tasks unexpectedly provided a task of type "shell".

Is something wrong with my tasks.json? I can't replicate this consistently? This does not happen when all extensions are disabled.

[taunusflieger]

Similar behavior here with ROS

The task provider for "catkin_cmake" tasks unexpectedly provided a task of type "catkin_make".
The task provider for "catkin_cmake_isolated" tasks unexpectedly provided a task of type "catkin_make_isolated".

This is there since one of the last Insider updates. My version

If I run task instead of build task, the issue will not appear.
And when I click "Show All Tasks" under drop-down list of normal run task, it shows again.

Same issue for me,

Commit: d69a79b73808559a91206d73d7717ff5f798f23c

but it will not appear on my vscode stable.

Version: 1.44.2 (system setup)
Commit: ff915844119ce9485abfe8aa9076ec76b5300ddd
C/C++ 0.28.0-insiders2

[sean-mcmanus]

@Primimy If the bug occurs on 1.45-insiders but not 1.44.2 (both with 0.28.0-insiders2) then that suggests it's a VS Code bug and not a bug with out C/C++ extension.

[alexr00]

In this extension's call to registerTaskProvider it registers a C\C++ task provider.

vscode-cpptools/Extension/src/LanguageServer/extension.ts

Lines 174 to 180 in ef120e8

	taskProvider = vscode.tasks.registerTaskProvider(taskSourceStr, {
	provideTasks: () => getBuildTasks(false),
	resolveTask(task: vscode.Task): vscode.Task | undefined {
	// Currently cannot implement because VS Code does not call this. Can implement custom output file directory when enabled.
	return undefined;
	}
	});

However, then it provides tasks of type shell not of type C\C++, which is unexpected. It used to work because VS Code was just blindly accepting all tasks. With the recent changes to the task quick pick to make it faster, it can't do that. I added this error message recently so that folks would notice this problem.

The quickest and most correct way for this extension to stop having this error would be to provide tasks of type C\C++. This will fix:

• The error in this bug
• Problems with these tasks showing in the "recent" section of the task picker that shows when you Run Task

That said, I'll make a small change to not show the notification in this case. Then, I'll see what can be done about the task not showing in the "recent" section.

+1.
After today's VSCode update, everytime I build with Platformio I see the "There are task errors. See the output for details"
After clicking the "Show Output" button it reports: The task provider for "C/C++" tasks unexpectedly provided a task of type "shell".

[sean-mcmanus]

We have a fix with https://github.com/microsoft/vscode-cpptools/releases/tag/0.28.0-insiders3 . We plan to release 0.28.0 on Monday (or maybe Tuesday).

[thomastech]

Thank you for the quick fix. Installed 0.28.0-insiders3. Issue resolved.

• Thomas

[Trafalgar99]

Good job,thank you.

[Gorgeous2017]

@sean-mcmanus

Nice.

But the terminal always displays the Terminal will be reused by tasks, press any key to close it. when tasks done.

Look like this:

I remember it didn’t appear before. It is a bug?

[imba-tjd]

@Gorgeous2017 It did appear before. It's basically similar to "press any key to continue"

Actually, if you don't configure a right path for gdb, this error will occur.

[astojanovic-tvz]

What if I'm not using GDB? I use MS C++.

[muhammad-osaid-tekfocal]

For those having hard time figuring this out,

1. Open VS Code and Go to extensions, right click C/C++ then click Extension Settings
2. Scroll down to last and "C-Cpp: Update channel" will be third last drop down list
3. Change from default to insiders. (this will be auto saved)
4. The downloading will start and will ask you to reload once completed AND you are done. :)
5. Try restarting VS code if step 4 does not asks you to reload. Be patient and pray for your internet speed till you see the reload message.

[lyq1996]

+1 Same problem here.

[astojanovic-tvz]

Thanks muhammad-osaid-tekfocal, it works like a charm! :)

[mangkoran]

is it okay to revert back to default update channel after updating?

[thomastech]

It's OK to revert back to the default Update Channel after installing the insiders release. The insider version will remain until a newer official release is available on the default Channel.

• Thomas

[sean-mcmanus]

@ayams02 We had a bug that prevented auto-downgrading from 0.28.0-insiders3 to 0.27.1 when the updateChannel changes to "Default" (#5464), but that should be fixed for future Insider releases...and we should be releasing 0.28.0 soon anyway.

[sean-mcmanus]

Fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/0.28.0 .

[thomastech]

Yoo-hoo! Platformio now reports it has 0.28.0 installed. @sean-mcmanus, Thank You.

• Thomas

[PogoRollo]

As of about an hour ago I have 0.28.0 installed and the issue is gone.
Thanks @ all the contributors!

[timeneverdie]

Fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/0.28.0 .

The default template of launch.json and task.json may be not correct as before. I generate many times to get the fine version to debug like before. I don't why, but this is the truth. Wish you could find out the real problem which causes this error. Thanks.
