Error: The PlatformIO task detection

1

Hello.
Every time I compile a program, I got the message below, what does it mean and how do I fix it ?

Error: The PlatformIO task detection didn’t contribute a task for the following configuration:
{

  • “type”: “PlatformIO”,*
  • “task”: “Build”,*
  • “problemMatcher”: [*
  •    "$platformio"*
  • ],*
  • “group”: “build”,*
  • “label”: “PlatformIO: Build”*
    }
    The task will be ignored.

Programs compile and works ok.
/Jens

Please read [Potential dupe] Error: The PlatformIO task detection didn't contribute a task and try the suggested steps:

  • Close VS-Code
  • Delete the .pio folder in your project
  • Delete the .vscode folder in your project
  • Restart VS-Code

If the error still occurs:

  • Close VS-Code
  • Delete C:\Users\<user>\.platformio folder
  • Restart VS-Code
  • Wait until PlatformIO reinstallation is finished

Deleting the .pio and .vscode folders did not solve the “problem”
I am not too keen to delete the .platformio folder, because I do not have the fully overview of what will happen to my libraries.
Thanks for responding. :+1:

What do you mean with “your libraries”?
If you didn’t store your private libraries within the .platformio folder, nothing will happen.

PlatformIO will reinstall it’s missing parts.

Okay. In the .platformio folder I have a lib folder, this folder contains 6 subfolders
(BlinkLed, Charlieplex, JLed, NmraDcc, U8g2, Useless)
I dont use them anymore, so I think it is ok to remove them or I can install them correctly later.

I am wondering how these libraries came into the .platformio folder.
Perhaps this is a relic from old times when global libraries were still used.

Usually libraries are installed per project (via the lib_dep setting in the platformio.ini file) and will end up in the projects .pio/libdeps/<envname>/<libname> folder.

Have deleted the C:/users/JJ/.platformio folder
Restarted PIO and waited for the new install to complete and restart.
Still the same Message / error when compiling !

Got a new message (OUTPUT tab) when starting PIO:
[5/5/2025, 11:40:10 AM] Unable to resolve configuration with compilerPath “C:/Users/JJ/.platformio/packages/toolchain-atmelavr/bin/avr-gcc.exe”. Using “C:/Users/JJ/.platformio/packages/toolchain-gccarmnoneeabi/bin/arm-none-eabi-gcc.exe” instead.
