I'm also suing dunfell branch, I did a small modification in
my_distro_version.bbclass:

def my_distro_version(d):
>     import subprocess
>     project_path = d.getVar('MY_LAYER_BASE', True)
>     cmd = "git describe --tags"
>     proc = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True,
> cwd=project_path)
>     out, err =  proc.communicate()
>     return out.decode("utf-8").rstrip()
> MY_DISTRO_VERSION := "${@my_distro_version(d)}"



Then in meta-mylayer/conf/distro/my_distro.conf I used:

> INHERIT += "my_distro_version"
> DISTRO_VERSION := "${MY_DISTRO_VERSION}"


It seems to be working now :-)


Thank you for the support :-)


cheers,
