Description

Hi,

there is no extended CI coverage to non-linux archs to indicate the lib can run on any of the non-linux architectures. It is currently broken on MS-Windows (see #246) and most probably has always been?

Moreover, the the build indicator on the front page although it indicates that the build is passing, it point to a 404 on the travis website.

In addition to this, the test suit fails to run on python greater than 3.10, due to the removal of a deprecated package path in python from collections.Mappings to collections.abc.Mappings. This is another indication that the travis suite (which I assume picks up the latest python version) is not working?

To reproduce on Linux run

[~/src/libpython-clj]$ python --version
Python 3.10.11

[~/src/libpython-clj]$ clj -M:jdk-17:test

As such, I'd like to make a suggestion to fix the above issue and extend the CI coverage across all mainstream architectures and python versions, PR to follow.

Research direction

The issue names the Travis CI suite and clj -M:jdk-17:test as the reproduction entry point; start by inspecting the CI configuration and running that command on the reported Python versions. Check the instance-abc-classes failure and the front-page build indicator. Done means CI covers the requested architectures and Python versions, the test suite passes, and the build link no longer returns 404.
