Build fails with CleanCommand super()-call

While trying to upgrade the BitBake recipes for python-semver (Python 2 and Python 3) from version 2.8.1 to 2.9.1, I’ve encountered the following error which seems to have been introduced by commit https://github.com/python-semver/python-semver/commit/017e29633562acc8ae9a76c7c8389424263dafd0#diff-2eeaed663bd0d25b7e608891384b7298L39-R39.

Here is the relevant BitBake log for Python 3.7:

And here is the corresponding log for Python 2.7:

Looking at the documentation for super() in Python 3 and Python 2 makes me wonder if super(CleanCommand, self).run() might be a typo and should have been super(Clean, self).run().

Changing super(CleanCommand, self).run() to super(Clean, self).run() apparently solves the problem for Python 3. For Python 2, the error message stays more or less the same:

ERROR: Execution of '/yocto/build/3.0-zeus/bbb/tmp/work/cortexa8hf-neon-poky-linux-gnueabi/python-semver/2.9.1-r0/temp/run.do_configure.2883' failed with exit code 1:

After applying CleanCommand.run(self) from #226, BitBake is able to build python-semver again. 😃

Below is the identical output of BitBake for both Python 2 and 3:

DEBUG: Executing shell function do_configure
running clean
semver.egg-info/ removed ...
DEBUG: Shell function do_configure finished
DEBUG: Executing python function do_qa_configure
DEBUG: Python function do_qa_configure finished

@menschel-d Cool! 👍 Thanks to @scls19fr for the quick merge! 👍
