Please update to 3.1.0a3 http://docs.platformio.org/en/stable/installation.html#development-version

Also, need to re-init project.

Thanks a lot for the report! 👍

@ivankravets Yeap, but not completely fixed.

I get new version by: pip install -U https://github.com/platformio/platformio/archive/develop.zip
create new project for clion.
But..., new error:

Error:Configuration Debug
Syntax error in cmake code at
  C:/Users/Ivan/Documents/test/CMakeListsPrivate.txt:51
when parsing string
  C:\Users\Ivan\Documents\test\src
Invalid character escape '\U'.

@ivankravets
Yeap, fixed 👍

[ivankravets]

Happy Coding with PlatformIO! :)

[ivankravets]

Don't forget that you need perform "Rebuild C/C++ Index" each time when add new library or change project settings.

[MeGaPk]

@ivankravets In Clion you mean "Reload Cmake project"?

And i have question, why after "pio lib instal ..." need use "pio init" for add this library to CMake file?

[ivankravets]

If you add new library, you need to run PLATFORMIO_REBUILD_PROJECT_INDEX target.

pio init commands work in both directions: as project generator, also as a way to update existing project. This complicated system. We don't use make or Cmake. We have own Python-based build system based on SCons tool.

So, when you run pio init we launch 100% real build environment and gather all required data for the specific IDE.

[MeGaPk]

@ivankravets just in my case:
I install new lib, but my Clion don't see new library... its very strange for newbie, like me.
By google, i found (not easy), need just use pio init... But for newbie, this is hell :).

[ivankravets]

Hm.. We write about it in documentation :) Firstly, need to check docs, then google.

We had a discussion with JetBrains as for the this issue. Need to write some plugin that will monitor PlatformIO's Library storages and platformio.ini file. If there are new folders or project file is changed, need to regenerate project index.

We do these in PlatformIO IDE where all work from a box without "google" :)
