Hi @Thoria94. Are you able to build the project from command line instead of Eclipse?

I suspect that this directory name is causing the issue: "Kütüphane". Please check that you haven't set it somewhere by mistake.

Hello @dobairoland, thank you for quick answer. I solved this problem 5 mins ago by updating my git version 2.21 to 2.29 after that my issue is gone. I hope this works for anyone who needs.

Let me add some info. It's recommended to use path for projects without special characters, because of encoding problems with some versions of Python and 3rd party tools.

Another option is to solve the problem is to enable "Use Unicode UTF-8 for worldwide language support" feature in the Windows ad described here: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/windows-setup.html

"System Administrator can enable the support via Control Panel - Change date, time, or number formats - Administrative tab - Change system locale - check the option “Beta: Use Unicode UTF-8 for worldwide language support” - Ok and reboot the computer."

Update regarding integration with Eclipse: ESP-IDF Tools Windows Installer 2.6+ contains support for installation of preconfigured Eclipse with ESP plugin. You can download the newer version of the installer here:
