Python error while installing ESP-IDF on eclipse

[Hasan Shadi]

I was trying to install ESP-IDF on eclipse 2019 version on windows 8.1 . First it gave me an error about the CMake version that it is a bit old or something, However, I searched deeply on the internet and found that ESP-IDF requires at least 3.5.0 of CMake version. So, I installed the exact version which is 3.5.0 of CMake. After that, I had another error which is not obvious, saying that a file is missing and nothing is described about that file:

    startupinfo)

And then, after some work, I reopened eclipse to try again and install the esp-idl tools again from the help menu. I got this error about CMake version, since I have a supported version, I don't know what is going on. This is the result:

Hi Hasan,

The problem could be with one of these.
1. It's getting failed while running "git describe --tags" command, so I'm guessing GIT is not in the PATH variable. To avoid this issue, while installing the tools from eclipse, it will ask for the GIT executable path - have you specified this correctly?
2. esp-idf version - make sure you're on esp-idf v4.0 and above

A couple of others things:
1. Use the latest idf-eclipse-plugin https://github.com/espressif/idf-eclips ... tag/v1.0.1
2. You can ignore CMake warning
3. Provide the error log if you still have the issue after fixing git path https://github.com/espressif/idf-eclips ... #error-log

Thanks
