Changing from #feature/stage to normal results in error

1

I’ve tried modifying
platform = https://github.com/platformio/platform-espressif32.git#feature/stage
to
platform = https://github.com/espressif/arduino-esp32.git

The change resulted in the inability to build a project:

Processing esp32doit-devkit-v1 (framework: arduino; platform: https://github.com/espressif/arduino-esp32.git; board: esp32dev)

This is not PlatformIO platform, but Espressif’s Arduino core for the ESP32. You probably want platform = https://github.com/platformio/platform-espressif32.git or just platform = espressif32 with framework = arduino to use PlatformIO’s Arduino-Core releases, as seen in Releases · platformio/platform-espressif32 · GitHub

You are very right indeed.
I didn’t pay enough attention.

I actually had platform = https://github.com/platformio/platform-espressif32.git#feature/stage before this screw-up.
I saw that arduino-esp-core got updated and I wanted to get that new release.
