I’ve suddenly started to encounter these types of “errors”. I have no idea why or how.

All I am doing is hitting CTRL+ALT+B.
I have also tried CTRL+SHIFT+B and it has the same result.

What happened ?

This is my platformio.ini :


[env:esp32-evb]
platform = https://github.com/platformio/platform-espressif32.git
board = esp32-evb
framework = arduino
board_build.flash_mode = qio
upload_port = /dev/ttyUSB0
monitor_port = /dev/ttyUSB0
monitor_speed = 115200
upload_speed = 115200
build_flags = -DCORE_DEBUG_LEVEL=5

#libraries
lib_deps =  https://github.com/me-no-dev/ESPAsyncWebServer.git
            https://github.com/me-no-dev/AsyncTCP.git

I have made new projects and I couldn’t get rid of these.
I have tried deleting .vscode and restarting VSCode,

I don’t have tasks.json inside .vscode.
I have created one and copied what I found here: Redirecting...

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "PlatformIO",
            "task": "Monitor",
            "problemMatcher": [
                "$platformio"
            ],
            "presentation": {
                "panel": "new"
            }
        }
    ]
}

And I still got those.

Same issue here.
For me this error came from a totally unrelated project, that I happened to have open, while building mine.
Removing the .vscode/tasks.json in that other project solved the issue for me.

Now I am wondering, how the Build button knows, which project to build. Does somehow visit them all, if I have multiple projects opened?

Yeah, VSCode does some weird things at times… if I have another project open as part of a multi-root workspace, if one of those other projects has a gulp task configured, but the current one doesn’t, VSCode whines about not being able to find the gulp task (which doesn’t exist :man_facepalming:).

That’s ingenious solution! Thank you so much, @jnweiger
The warning message was not critical but annoying…

I have about a dozen of projects in parallel for years and never encountered this problem.
Today it popped up suddenly. It took me some time to imagine which “other project” makes VScode crazy.

Thanks for sharing your solution.
