Configuration

Operating system: macOS Sonoma Version 14.2

PlatformIO Version (platformio --version): PlatformIO Core, version 6.1.16

Description of problem

Here's my directory structure:

arduino
├── platformio.ini
├── arm_atmega1280.ino
├── receiver_esp8266.ino
├── remote_esp8266.ino
└── servo_debug.ino

I'm wondering if there's a way to specify the environment to run a different file?
Or can I specify a file to compile and upload?

By the way, this is for my project darkchess-robot. Thanks for your help!

Steps to Reproduce

1. cd to arduino directory
2. Run pio run -e remote, then it prints error message.
3. Run pio run -e receiver, then it also prints error message.

Actual Results

Error message by step 2:

Error: Nothing to build. Please put your source code files to the '/my/workspace/dir/arduino' folder.

Error message by step 3:

Error: Nothing to build. Please put your source code files to the '/my/workspace/dir/arduino' folder

Expected Results

Successfully compile and upload to board.

If problems with PlatformIO Build System:

The content of platformio.ini:

[platformio]
src_dir = .

[env:remote]
platform = espressif8266
board = esp07
framework = arduino
src_filter = +<remote_esp8266.ino>

[env:receiver]
platform = espressif8266
board = esp07
framework = arduino
src_filter = +<receiver_esp8266.ino>

[env:arm]
platform = atmelavr
board = ATmega1280
framework = arduino
src_filter = +<arm_atmega1280.ino>

[env:debug]
platform = atmelavr
board = ATmega1280
framework = arduino
src_filter = +<servo_debug.ino>
