Does PyGradle work with Python3.8 - re.py line 145 enum no attribute IntFlag

[jshingler]

Okay, ... Still a newbie to python, ... I use gradle in professional life, ... I was excited to see python plugin for gradle, ...

been looking into this off and on for 2 days, .... thought maybe I was doing something wrong, ... starting to think that maybe pygradle doesnt work work Python3.8?

See output below.

gradle build

Even set it up in a NEW Docker container just to make sure something in my environment wasn't the problem.

this enum problem you just need to force version, I found it somewhere in the issue a while ago.
python {
... other config ...
forceVersion('pypi', 'flake8', '3.2.1')
forceVersion('pypi', 'six', '1.13.0')
}

For anyone still struggling, yes with some effort pygradle does work with Python3.8.
See pygradle_python3_example for details: https://github.com/alghoshal/pygradle_python3_example/blob/main/README.md
Also my comment on another issue: #351 (comment)

For the enum bit, that's primarily a flake8-3.6 dependency on enum34, which is not supported in Python-3.

See fixDownloadedIvyModules.sh (Line No 25) for removal of the dependency from the flake8-3.6.0.ivy file:
