On tonights stream, we started doing some work on the Cake.BuildSystems.Module, which is part of the Cake-Contrib GitHub Organisation:
https://github.com/cake-contrib/Cake....
On the stream, we were able to review a PR into this repository to add support for grouping of log messages in GitHub Actions (which was provided by Nils) and ship version 4.2.0.
Once this was done, we started looking at what is required to update the Module to use the latest version of Cake, since doing this provides the ability to write out to the step summary of a GitHub Actions workflow. We stubbed out an implementation of the ICakeReportPrinter, to take advantage of this, but this will need some more work, which I am hoping to continue next week.
