I cannot get to work code autocompletion in Clion.

I have followed this guide ( and installed PIO Core, then I have created a new blink project. I have managed it to work from command line.
(Just created a main.cpp with "blink" content and executed pio run -t upload. It works nice).

However I need autocompletion in CLion. I have added a line
add_executable(myproject src/main.cpp)
into CMakeLists.txt, but i doesn't help.

Could you try to repeat pio init --ide clion when you modify src or lib folder? Restart CLion, it should work.

Currently experiencing this issue. Running PLATFORMIO_REBUILD_PROJECT_INDEX causes CLion 2018.3.1 to forget pio and platformio commands. Running pio init --ide clion does re-init the project, but code completion still throws errors such as Arduino.h being nonexistent. 😢

Fixed in 9f4dde4

Please run in CLI pio upgrade --dev and re-init project. Does PLATFORMIO_REBUILD_PROJECT_INDEX work now?
