Great to hear Joseph! Regarding the test errors that you observe, as Ralph
has also noted, we are aware of them, hence the -DskipTests flag in the
commands I have shared with you. For reference, you can check our CI
pipelines on GitHub <https://github.com/apache/logging-log4j2/actions> and
Jenkins
<https://ci-builds.apache.org/blue/organizations/jenkins/Logging%2Flog4j/activity>.
Some of those failures, particularly in release-2.x branch, are
Windows-specific. A majority of the active Log4j developers don't have
access to a Windows development machine, hence, given you have a Windows
machine, we would really appreciate it if you can spare some time to
investigate and maybe even fix them!
